- Abstract
Heading into 2022, energy experts debated the speed and timing of a return to "normal" energy demand following a tumultuous 2020–2021 as the world responded to the COVID-19 pandemic. As vaccines became widely available in the first half of 2021, optimism grew in the energy economy as demand quickly headed back to pre-pandemic levels. In many cases, energy demand increased faster than supply, causing significant run-ups in prices, as well as supply chain constraints. These problems were compounded when Russia invaded Ukraine causing more disruption to energy supplies. Overall, the higher energy prices and the greater demand spurred increases in local drilling and production of oil and natural gas. In addition, the federal administration maintains an emphasis on a transition to carbon-neutral energy sources, most acutely seen in the electric utility sector with a continued shift away from coal to more renewable sources.

- Abstract
This thesis examines the local economic and health impacts of natural resource extraction on communities and the effectiveness of large energy subsidies using microdata from Mongolia for 2008-2018. The results are presented in three stand-alone empirical chapters. Chapter 2 examines the economic impacts of the mining industry's indirect linkages on household expenditure patterns in a quasi-experiment setting. Households benefit from mining activities by increasing their expenditures on food, health care, and electricity by reducing their expenditures on education, non-food goods, and services. However, increased mining activities do not adversely affect health and educational outcomes because of improved access to health and education services. Chapter 3 investigates the impact of mining-induced pollution on individuals' likelihood of reporting illnesses, employing a novel instrumental variable. Individuals who reside within five kilometers of mining activities are more likely to report illness. This is true for all age groups, although the effect is most severe for younger children. Small-scale mines and gold mines cause greater health risks than larger and other types of mines. Chapter 4 evaluates the effectiveness of large electricity subsidies in reducing fossil fuel use, such as coal, and improving ambient air quality. The subsidy program achieves its intended goal of reducing illness, but it affects household electricity consumption behavior, which might further help the transition from coal to electricity and reduce air pollution. The results reported in this thesis generate findings important for policymaking in resource-rich developing countries. First, household disaggregated expenditure analysis can provide useful information about household consumption decisions, which can be used for policy formulation to increase the benefits of mining activities to local communities. Second, pollution control and mitigation are essential in resource-producing regions

- Abstract
En el desarrollo de este trabajo se estudia la situación de la industria minera frente a la problemática medioambiental actual, por medio de una revisión extensa de la literatura de las que se incluyeron a lo largo del trabajo citas relevantes de informes, revistas y otros documentos de interés. Se identifican factores impulsores y alternativas que las empresas pueden implementar para la reducción de emisiones de CO2 y otras sustancias o para mitigar los daños producidos, tales como, mejoras en sus procesos, electrificación de vehículos y otras innovaciones de transporte, compensaciones y captura de carbono, o el uso de hidrógeno. También se identifican obstáculos técnicos, de experiencia y financiación que van a influir en la velocidad de la integración de tecnologías de descarbonización. Una vez hecho este trabajo de investigación, se seleccionan datos bibliográficos y analíticos de la producción de oro en la República Dominicana y por medio de la metodología de Análisis de Ciclo de Vida (ACV), utilizando el software SimaPro como herramienta, se evalúan las cargas del uso de combustibles fósiles en equipos móviles y electricidad en otros equipos de procesamiento de minerales. A partir del análisis realizado se plantean recomendaciones en forma de propuestas viables que ayuden la reducción del dióxido de carbono de las fuentes de energía, y, por tanto, a mitigar los impactos identificados. A su vez, se persigue que estas propuestas puedan servir de guía a otras empresas mineras, productores de energía independientes e instituciones de desarrollo sobre cómo acelerar la integración de las energías renovables en el sector minero., In the development of this work, the situation of the mining industry in the face of current environmental problems is studied by means of an extensive review of the literature, including relevant quotes from reports, journals and other documents of interest. Drivers and alternatives that companies can implement to reduce emissions of CO2 and other substances or to mitigate the damage produced are identified, such as improvements in their processes, electrification of vehicles and other transport innovations, carbon offsets and carbon capture, or the use of hydrogen. It also identifies technical, experience and funding barriers that will influence the speed of integration of decarbonization technologies. Once this research work is done, bibliographic and analytical data on gold production in the Dominican Republic is selected and by means of the Life Cycle Analysis (LCA) methodology, using SimaPro software as a tool, the burdens of the use of fossil fuels in mobile equipment and electricity in other mineral processing equipment are evaluated. Based on the analysis, recommendations are made in the form of viable proposals to help reduce carbon dioxide from energy sources and, therefore, mitigate the identified impacts. In turn, these proposals are intended to serve as a guide to other mining companies, independent power producers and development institutions on how to accelerate the integration of renewable energies in the mining sector.

- Abstract
Background: The health and safety of the miners in the South African mining industry are guided by the regulations and standards which are anticipated to promote a healthy work environment and fatalities. It is of utmost importance for the miners to comply with these regulations/standards to protect themselves from potential occupational health and safety risks, accidents, and fatalities. Purpose: The purpose of this study was to develop and validate strategies to enhance compliance with the Health and safety standards within the mining industries of Limpopo province in South Africa. Methods: A mixed-method exploratory sequential research design was adopted. The population consisted of 5350 miners. Purposive and total sampling was used to select the participants in the qualitative strand and stratified random sampling in the quantitative strand. Semi-structured interviews were conducted among the occupational health nurse practitioners and the health and members of the health and safety team. Thematic analysis was used to generate an understanding of the interviews. In the quantitative strand, a survey was conducted using a self-administered questionnaire. Data were analysed using SPSS version 26.0. A descriptive statistical test was used in the analysis of data including frequencies, means, and standard deviation. Cronbach's alpha test was used to measure internal consistency. Results: The integrated results revealed that there are diverse experiences related to health and safety standards compliance among the mineworkers. The main findings were challenges related to leadership compliance and also related to the cost of maintaining safety, Miner's behaviour-related challenges; the impact of non-compliance on the overall health of the miners was also described, the conflict between production and safety. As a result, strategies to enhance compliance of health and safety standards at the selected mining industries in Limpopo province, South Africa were developed. Con

- Abstract
La literatura sugiere que los residuos resultantes de la actividad minera no son completamente explotados y, como resultado, estos quedan acumulados y sin ningún uso o aplicación. En Castellgalí, localidad situada en Cataluña, se procesa calcarenita para la elaboración de roca ornamental, lo cual deja una gran cantidad de residuos de tamaño de grano muy fino producidos a causa de las operaciones de corte. Esta roca es rica en calcita y puede ser usada como un agente fundente en la fabricación de vidrio o como un componente principal para la producción de cemento. Por este motivo, esta investigación analiza el tratamiento que se le podría dar a la roca para ser usada para la fabricación de ambos productos. La composición química del residuo ha sido analizada con fluorescencia de rayos X (FRX), la cual mostró que la roca está principalmente constituida de SiO2 y CaO y, subsecuentemente, ha permitido realizar una formulación para la fabricación de vidrio y cemento al mezclarlo con diferentes componentes para obtener una composición teórica apropiada. Adicionalmente, para poder fabricar vidrio varios autores usaron residuos mineros y tuvieron que añadir CaCO3 puro. En esta investigación, se usaron residuos de Barruecopardo (Salamanca, España) para formular vidrio con la adición del residuo de la roca ornamental de Castellgalí. Para saber la viabilidad de dicha producción, se ha calculado de la trabajabilidad del vidrio con formulas de Fluegel, las cuales toman en cuenta la temperatura y viscosidad del vidrio. Por otro lado, para la obtención de cemento, ya que la roca es abundante en calcita, ésta fue mezclada con dos bauxitas: una rica en hierro y otra rica en aluminio. Se ha obtenido que, en ambos casos, un cemento con buenas propiedades podría ser fabricado. Sin embargo, aunque buenos productos pueden ser fabricados con los residuos de Castellgalí, estos tendrían ciertas características a tener en consideración. El vidrio producido tendría una tonalidad oscura, el c, The literature suggests that tailings resulting from the mining industry are not fully exploited and, as a result, these are left in-situ without any further use or application. Such tailings could be used for the fabrication of products such as glass or cement. In Castellgalí, Catalonia, calcarenite ornamental rocks are processed and a large quantity of fine-sized waste is produced as result of the sawing process. This rock is calcite-rich and could be used as a flux agent for the manufacturing of glass and as a main component for the production of cement. Therefore, this research analyses the treatment that could be given to this rock to be used in the manufacture of glass and cement. The chemical composition of the rock wastes from Castellgalí has been obtained through X-Ray fluorescence (XRF), showed that this rock is mainly composed of SiO2 and CaO and subsequently, allowed us to made a glass and cement formulation by mix it with the different components to obtain a theoretical suitable composition. Moreover, in order to fabricate glass several authors used tailings from many activities and they added pure CaCO3. In this research we used the tailings from the Barruecopardo mine (Salamanca, Spain) to formulate glass with the addition of the Castellgalí waste. To know how feasible its production is, the glass workability has been calculated with the formulas by Fluegel, which account for temperature and viscosity. On the other hand, since calcite is the main component of this rock, it was mixed with two different bauxites: one rich in iron, and another one rich in aluminum. In both cases, a good cement could be fabricated. A cement with a suitable chemical composition for produce Portland cement was obtained. Even though good products could be fabricated with the calcarenite waste from Castellgalí, they would be far from perfect. Glass produced would have a dark tone, this would need to be accounted for if it is used from construction. Nevertheless, this research

- Abstract
[SPA] Esta tesis doctoral se presenta bajo la modalidad de compendio de publicaciones. Actualmente, la gran minería del cobre chilena se encuentra frente a nuevos problemas y desafíos a superar. El principal problema, es de carácter medio ambiental, debido a que la mayor parte de la producción es por procesos de flotación, lo que implica aumentar la generación de relaves, ocasionando drenajes ácidos que generan la movilidad de elementos pesados al medio ambiente. Otro desafío importante, es diversificar las extracciones de otros elementos (como ocurre actualmente con el molibdeno) para impulsar la exportación de productos básicos y aumentar el empleo. Además, se deben tratar recursos que hoy en día no se están aprovechando a escala industrial, un ejemplo son los minerales de cobre negro, estos recursos generalmente no se incorporan en las pilas de lixiviación. Estos minerales exóticos tienen cantidades considerables de Mn (aproximadamente 29%), lo que representa un atractivo comercial. Para abordar este desafío, se realizaron investigaciones a nivel laboratorio, de extracción de cobre y manganeso desde cobres negros mediante procesos de lixiviación. Se evaluaron diferentes aditivos y concentraciones de estos mediante la aplicación de modelos estadísticos de regresión cuadrática, evaluando efectos lineales, interacciones y curvaturas. Además, se diseñaron y probaron con éxito nuevos procesos de extracción. Finalmente, se pudo demostrar que para la disolución de Mn ya sea desde nódulos marinos o cobres negros, se obtienen resultados positivos al adicionar Fe en el sistema, siendo un parámetro óptimo de trabajo una razón de MnO2/Fe de 1/2, logrando extracciones sobre el 70% en tiempos de 20 min. Para la disolución de Cu desde sulfuros secundarios, se puede concluir que los mejores resultados se obtienen al trabajar a elevadas concentraciones de cloruro, siendo poco relevante la concentración de H2SO4. Por otra parte, para la disolución de calcopirita, trabajar en un me, [ENG] This doctoral dissertation has been presented in the form of thesis by publication. Currently, the great copper mining is facing new problems and challenges to overcome. The main problem is environmental, because most of the production is due to flotation processes, which implies increasing the generation of tailings, causing acid drains that generate the mobility of heavy elements to the environment. Another important challenge is to diversify the extractions of other elements (as is currently the case with molybdenum) to boost the export of basic products and increase employment. In addition, resources that are not currently being used on an industrial scale should be treated, an example is black copper ores, these resources are generally not incorporated into the extraction circuits or are not treated, whether in stocks, platforms leaching or waste. These exotic minerals have considerable amounts of Mn (approximately 29%), which represents a commercial appeal. To address this challenge, research was carried out at the laboratory level, for the extraction of copper and manganese from minerals through leaching processes. Evaluating different additives and concentrations thereof, applying the use of statistical models of quadratic regression, evaluating linear effects, interactions and curvatures. And in other cases, creating new extraction processes. Finally, it was discovered that for the dissolution of Mn either from marine nodules or black copper, very positive results are obtained by adding Fe in the system, an optimal working parameter being a ratio of MnO2/Fe of 1/2, achieving extractions above 70% in times of 20 min. For the dissolution of Cu from secondary sulphides, it was found that the best results are obtained when working at high concentrations of chloride, the concentration of H2SO4 being insignificant. On the other hand, for the dissolution of chalcopyrite, working in a chlorinated medium incorporating high concentrations of MnO2 (ratios of MnO

19. COVID-19 Energy Sector Status Report, May 4, 2020
- Abstract
To assist Utah residents and businesses during the COVID-19 pandemic, the Governor's Office of Energy Development (OED) and the Utah Geological Survey (UGS) are partnering to compile information on the status of Utah's energy and mineral sectors. The COVID-19 pandemic is creating unprecedented market uncertainty, disrupting supply chains, and significantly altering the overall demand for energy and materials here in Utah and abroad. After over a month of shelter-in-place orders, the energy and mining sector is facing many challenges; including declining demand for goods, resources and services, overproduction, limited financing opportunities, project postponements and cancellations, insufficient quantities of personal protective equipment (PPE) for essential personnel, consumer uncertainty, and disrupted supply chains. We are seeing the true impact of COVID-19 on the industry and are now beginning to identify the short-term energy outlook, while managing uncertain long-term projections for late 2020 and beyond.

20. COVID-19 Energy Sector Status Report, June 10, 2020
- Abstract
To continue assisting Utah residents and businesses during the COVID-19 pandemic, the Governor's Office of Energy Development (OED) and Utah Geological Survey (UGS) are partnering to provide up-to-date information on the status, impacts, and efforts underway to support Utah's energy and mineral sectors. The energy and mineral sectors in Utah are continuing to face varying degrees of market uncertainty and disruption due to the COVID-19 pandemic. While production and employment numbers are still below average, some industries are beginning to show an upward trend after reaching record lows in April 2020. On May 15, Gov. Gary R. Herbert issued an Executive Order moving the majority of Utah's counties to the Low Health Risk Status (Yellow), helping alleviate some of the challenges to local businesses. In addition to the relaxing of restrictions and opening of businesses, coordination efforts between the Utah Department of Public Safety and Utah's oil, gas, and mining industries has resulted in increased testing operations and distribution of safety equipment along the Wasatch Front, Uinta Basin, and central Utah. As Utah's energy and mineral sectors recover, continued support is needed as outlooks, partnerships, and safety protocols are established to address the impacts of the COVID-19 pandemic.

- Abstract
Recent analyses indicate a historical decline of 11 feet in Great Salt Lake water levels due to human development and use of water in its watershed; a decline most recently accentuated by the recent drought of the 2000s and near-record low lake water levels in 2016 and 2018. A preliminary assessment of future conditions in Great Salt Lake’s Watershed suggests this trend may continue with lake water levels continuing to decline. The worldwide decline and loss of similar saline lakes provides further perspective on the possibility, the consequences, and the opportunities the State of Utah must consider as it evaluates the resiliency of Great Salt Lake and that of the communities located on its shoreline.

- Abstract
Strategy No. 1: Allow irrigators or other water users to send unneeded water downstream without being penalized or risk losing their water rights. The Issue: Presently, Utah Water Law discourages conservation of water by penalizing water right owners who do not use the full quantity of their water rights, providing no incentive for users to use less water. Water in Utah is owned by the public and governed by the Prior Appropriation Doctrine. Developed in the 19th century to advance western settlement and resolve disputes between competing parties, the Prior Appropriation Doctrine's primary function is to promote and manage the use of scarce, and therefore valuable, water resources. The law discourages wasting water and conditions the issuance of water rights on the requirement that water be put to use in a way that benefits society, commonly known as "beneficial use."

- Abstract
The purpose of this report is to assess the potential costs of declining water levels in Great Salt Lake and its wetlands. A multitude of people, systems, and wildlife rely on Great Salt Lake and value the services it provides. Declines in lake levels threaten current uses, imposing risks to livelihoods and lake ecosystems. This report synthesizes information from scientific literature, agency reports, informational interviews, and other sources to detail how and to what extent costs could occur at sustained lower lake levels. Water diversions from the rivers that feed Great Salt Lake have driven historical declines in lake levels. Current and future water stressors, without intervention to protect or enhance water flows to Great Salt Lake, have the potential to deplete water levels even further. Declines in lake levels threaten the business, environmental, and social benefits that Great Salt Lake provides and could result in substantial costs to surrounding local communities and the State of Utah. This report traces the pathways and resulting costs that could arise due to declines in water levels in Great Salt Lake. The potential costs evaluated in this report include those caused by reduced lake effect, increased dust, reduced lake access, increased salinity, habitat loss, new island bridges, and the spread of invasive species.

- Abstract
The Utah Department of Natural Resources Division of Forestry, Fire and State Lands (FFSL) first developed a mineral leasing plan (MLP) for sovereign lands on the Green and Colorado Rivers in 1998. The 1998 MLP provided a brief history of mineral ownership and leasing, inventoried mineral resources, examined existing resource conflicts on the rivers, and outlined management direction (FFSL 1998). The 1998 MLP has been amended six times since the date of final approval. This 2020 Green and Colorado Rivers MLP has been developed to update, consolidate, and replace the 1998 plan and all associated amendments. This plan is not intended to assert State of Utah ownership or adjudicate or resolve any ownership or title issues. It is intended to be used as a management tool only for lands owned by the State of Utah. Issues related to ownership and title may be resolved formally or informally in separate proceedings.

- Abstract
The existence of architecture that evokes defining moments of possibilities where its users are able to transcend the unseen tying threads of the system. Moments that create a new awareness to the narrative presented; the overarching segmented mining history of South Africa. Divulging the tragic and sanguine realities surrounding this controversial field, by exposing the tension that exists between mines, miners and the fragility of its support systems. Focusing on singular prominent examples throughout history, to convey a narrative by means of structure and spatial experiences. Leaving the conclusion of the narrative to the user. In hopes to help develop a better society by revealing truths and providing a home for initiatives that support objectives surrounding mine communities, polluted landscapes and sustainable new methods in these areas.

- Abstract
Utah's diverse energy industry plays a significant role in the state's economy. It encompasses traditional fossil fuels and renewable resources. The mining sector produces crude oil, natural gas, and coal. Power producers generate electricity from hydropower, geothermal, solar, wind, and biomass resources and distribute it within the state and across the western U.S. Five refineries process crude oil from Utah, Colorado, Wyoming, and Canada, and Utah has the only licensed and operating uranium mill in the country. Dozens of firms manufacture machinery for mining and the oil and gas fields as well as turbines, generators, transformers, and other electrical equipment. There are more than 60 petroleum wholesalers and 30 fuel dealers across the state. Solar installation and energy efficiency activities support thousands of jobs.

- Abstract
The purpose of this report is to assess the potential costs of declining water levels in Great Salt Lake and its wetlands. A multitude of people, systems, and wildlife rely on Great Salt Lake and value the services it provides. Declines in lake levels threaten current uses, imposing risks to livelihoods and lake ecosystems. This report synthesizes information from scientific literature, agency reports, informational interviews, and other sources to detail how and to what extent costs could occur at sustained lower lake levels. Water diversions from the rivers that feed Great Salt Lake have driven historical declines in lake levels. Current and future water stressors, without intervention to protect or enhance water flows to Great Salt Lake, have the potential to deplete water levels even further. Declines in lake levels threaten the business, environmental, and social benefits that Great Salt Lake provides and could result in substantial costs to surrounding local communities and the State of Utah. This report traces the pathways and resulting costs that could arise due to declines in water levels in Great Salt Lake. The potential costs evaluated in this report include those caused by reduced lake effect, increased dust, reduced lake access, increased salinity, habitat loss, new island bridges, and the spread of invasive species.

- Abstract
Recent analyses indicate a historical decline of 11 feet in Great Salt Lake water levels due to human development and use of water in its watershed; a decline most recently accentuated by the recent drought of the 2000s and near-record low lake water levels in 2016 and 2018. A preliminary assessment of future conditions in Great Salt Lake’s Watershed suggests this trend may continue with lake water levels continuing to decline. The worldwide decline and loss of similar saline lakes provides further perspective on the possibility, the consequences, and the opportunities the State of Utah must consider as it evaluates the resiliency of Great Salt Lake and that of the communities located on its shoreline.

- Abstract
Strategy No. 1: Allow irrigators or other water users to send unneeded water downstream without being penalized or risk losing their water rights. The Issue: Presently, Utah Water Law discourages conservation of water by penalizing water right owners who do not use the full quantity of their water rights, providing no incentive for users to use less water. Water in Utah is owned by the public and governed by the Prior Appropriation Doctrine. Developed in the 19th century to advance western settlement and resolve disputes between competing parties, the Prior Appropriation Doctrine's primary function is to promote and manage the use of scarce, and therefore valuable, water resources. The law discourages wasting water and conditions the issuance of water rights on the requirement that water be put to use in a way that benefits society, commonly known as "beneficial use."

46. COVID-19 Energy Sector Status Report, June 10, 2020
- Abstract
To continue assisting Utah residents and businesses during the COVID-19 pandemic, the Governor's Office of Energy Development (OED) and Utah Geological Survey (UGS) are partnering to provide up-to-date information on the status, impacts, and efforts underway to support Utah's energy and mineral sectors. The energy and mineral sectors in Utah are continuing to face varying degrees of market uncertainty and disruption due to the COVID-19 pandemic. While production and employment numbers are still below average, some industries are beginning to show an upward trend after reaching record lows in April 2020. On May 15, Gov. Gary R. Herbert issued an Executive Order moving the majority of Utah's counties to the Low Health Risk Status (Yellow), helping alleviate some of the challenges to local businesses. In addition to the relaxing of restrictions and opening of businesses, coordination efforts between the Utah Department of Public Safety and Utah's oil, gas, and mining industries has resulted in increased testing operations and distribution of safety equipment along the Wasatch Front, Uinta Basin, and central Utah. As Utah's energy and mineral sectors recover, continued support is needed as outlooks, partnerships, and safety protocols are established to address the impacts of the COVID-19 pandemic.

- Abstract
To assist Utah residents and businesses during the COVID-19 pandemic, the Governor's Office of Energy Development (OED) and the Utah Geological Survey (UGS) are partnering to compile information on the status of Utah's energy and mineral sectors. The COVID-19 pandemic is creating unprecedented market uncertainty, disrupting supply chains, and significantly altering the overall demand for energy and materials here in Utah and abroad. After over a month of shelter-in-place orders, the energy and mining sector is facing many challenges; including declining demand for goods, resources and services, overproduction, limited financing opportunities, project postponements and cancellations, insufficient quantities of personal protective equipment (PPE) for essential personnel, consumer uncertainty, and disrupted supply chains. We are seeing the true impact of COVID-19 on the industry and are now beginning to identify the short-term energy outlook, while managing uncertain long-term projections for late 2020 and beyond.

- Abstract
Las nanopartículas metálicas (MNPs) presentan una amplia relación superficie-volumen que proporciona propiedades únicas y mejoradas en comparación con el material macroscópico. Una de sus aplicaciones consiste en la adsorción de contaminantes, motivo por el cual la síntesis de MNPs de diferentes metales utilizando diversas metodologías está en amplio desarrollo. En este trabajo se propone la obtención de nanopartículas metálicas de diversos metales mayoritarios (Al, Fe, Zn, Cu, Cd y Pb) así como de otros metales más minoritarios (Ce, Nd, Pr, Dy y Sm) procedentes de aguas del drenaje ácido de minas (acidic mining drainage, AMD). Para ello, inicialmente se simularán dichas aguas utilizando patrones de diferentes metales. Se sintetizarán NPs con dos procedimientos diferentes: en uno se utilizarán reactivos químicos para la reducción del metal y para la estabilización de las nanopartículas metálicas (se utilizaría NaBH4 como reductor), mientras que en el otro se realizará mediante extractos naturales y reactivos sostenibles para el medio ambiente. El objetivo es comprobar si ambos procedimientos son equiparables y, por lo tanto, se haría una aportación a la
