For the increasingly important preservation of existing structures, strengthening with carbon reinforced concrete has proven to be an effective option in recent years. With the CARBOrefit® process, this type of flexural strengthening has been approved by the building authorities in Germany. Thin layers of carbon reinforced concrete are applied to existing concrete structures for repair or to increase the load-bearing capacity. The materials, the dimensioning and the procedure, including the boundary conditions, are described in the general technical approval with the number Z-31.10-182 (DIBt, 2021) and are presented in this article. In addition, the requirements for contractors are specified., Paper 243

The use of textile reinforced concrete (TRC) as a strengthening measure is a simple way of maintaining existing concrete structures and ensuring their long-term load-bearing capacity and serviceability. This method offers clear economic and technical advantages over conventional methods such as shotcrete, particularly for heritage structures. The thin strengthening layers are barely visible and preserve the original visual appearance, while introducing only a small amount of additional weight and moisture. A large number of listed buildings, complex shell structures and even bridges, have been repaired or strengthened using this construction method. The most important of these practical applications are presented here., Paper 241

In 2016 more than 1.35 billion smartphones have been manufactured (TrendForce Corp. 2017). Smartphones can contain up to 60 different elements and the summarized metal weight of the 2016 production is very likely more than 50,000 tons (The Royal Society of Chemistry 2017, 911Metallurgist 2013). However, at present, very few of the elements contained in these devices are recycled at recycling rates of more than 50%. For most elements, the recycling rates are significantly lower than 50%, and the recycling rates of rare earths, indium, tantalum or gallium are even below 1% (Compound Interest 2015)! The major challenge of mobile phone recycling is the complex composition of the devices made of many individual components. This is aggravated by the fact that many elements occur in traces only and / or are located in highly complex material composites. To enable more effective recycling of mobile phones, it is imperative to characterise their components, the presence of elements in it, as well as the crushing behaviour as detailed as possible. In a pilot study, a Nokia mobile phone Model 5228 Type RM-625, crushed with a Universal Granulator UG300 by colleagues of the Professorship of recycling machines of the TU Bergakademie Freiberg, was examined by Mineral Liberation Analysis (MLA). The analysis on three sieve fractions of the comminuted material was carried out with an MLA 650F at the Helmholtz Institute Freiberg for Resource Technology. The samples were scanned in an automated MLA measurement with a grid of EDX spectra (GXMAP mode). A total of 130 different phases were detected during the analysis. More than 100 of these phases occur at levels

‘Automated Mineralogy’ terms an analytical method that is based on a combination of scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). We suggest to use the term ‘Automated Materials Characterisation’ instead in certain cases, since not only minerals but other solid substances can be characterised by this method. The range of solid natural and artificial materials that has been investigated includes minerals, ores, rocks, mineral beneficiation products and tailings, metals, alloys, slags, construction materials, ceramics, glasses as well as recycling and semiconductor materials and even extraterrestrial materials. Automated mineralogical investigations provide the unique opportunity to place quantitative constraints on a multitude of parameters tangible for the development and critical evaluation of beneficiation test work. This includes modal mineralogy, calculated elemental content, elemental distributions, mineral associations, particle and mineral size distributions, particle density distributions as well as liberation [3]. Sample overview images (‘mineral maps’) and images of specific mineral groups can also be extracted from the analysis data. Of particular value is Automated Mineralogy in the field of processing of mineral raw materials. Here, the analyses generate an improved material understanding and are used for evaluation and optimisation of mineral beneficiation processes. Application leads to the reduction of raw material losses coupled with an increased resource and energy efficiency, and thus higher revenue for the operation. Recent research has shown that automated mineralogy data can be used to establish particle-based grade-recovery curves for minerals and elements from feed compositions – and expand the assessment of process efficiencies to include particle distribution probabilities. The value of Automated Mineralogy is widely recognized in the minerals industry. Yet, its application is most widespread in the characterization of noble (Au, PGE) and base metal (especially Cu, but also Ni) ores and processing streams. The two case studies presented here for Li and Co ores serve to illustrate the potential of Automated Mineralogy during the beneficiation of minor commodities (such as Li) and beneficiation products, including by-products (such as Co). Automated Mineralogy is found to be an analytical method suitable to provide robust quantitative mineralogical data on very complex raw materials; current research extends its application to the characterization of recycling materials. The method is already very well established and an essential part of most studies in the field of processing of primary raw materials, whereas in the case of recycling raw materials only a few sample studies indicate the potential of the method.

Mobiltelefone, von denen im Jahr 2016 weltweit über 1,4 Milliarden Geräte hergestellt wurden, können bis zu 60 verschiedene Elemente enthalten (TrendForce Corp., The Royal Society of Chemistry). Gegenwärtig werden allerdings nur sehr wenige der in den Mobiltelefonen enthaltenen Elemente mit Recycling-Raten von mehr als 50 % recycelt (Compound Interest). Bei den meisten Elementen liegt die Recycling-Rate bei deutlich unter 50 % und bei den Seltenen Erden, Indium, Tantal oder Gallium sogar bei unter 1 %! Ein Hauptproblem beim Recycling von Mobiltelefonen ist ihre komplexe Zusammensetzung aus vielen Einzelbauteilen. Erschwerend kommt hinzu, dass viele Elemente kommen nur in Spuren vorhanden sind und / oder sich in hoch-komplexen Materialverbunden befinden. Um ein effektiveres Recycling der Mobiltelefone zu ermöglichen, ist es unumgänglich ihre Bauteile, das Vorkommen der Elemente darin, sowie das Zerkleinerungsverhalten möglichst detailliert zu charakterisieren. In einer Pilotstudie wurde ein, vom Lehrstuhl für Recyclingmaschinen der TU Bergakademie Freiberg, mit einem Universal-Granulator UG300 zerkleinertes Nokia-Mobiltelefon Modell 5228 Typ RM-625 mit Hilfe von Mineral Liberation Analysis (MLA) untersucht. Die Analyse an drei Siebfraktionen des zerkleinerten Materials erfolgte mit einer MLA 650F am Helmholtz-Institut Freiberg für Ressourcentechnologie. Eine erste manuelle Aufnahme von Rückstreuelektronenbildern zeigt unter anderem Metallphasen mit einer Kleinheit von < 0,5 µm. Nachfolgend wurden die Proben in einer automatisierten MLA-Messung mit einem Gitternetz von EDX-Spektren abgerastert (GXMAP-Modus). Insgesamt wurden bei der Analyse ca. 130 verschiedene Phasen detektiert. Mehr als 100 davon treten mit Anteilen von < 1 Gewichtsprozent auf. Ein Vergleich des Modalbestandes der drei Siebfraktionen zeigte eine Anreicherung bestimmter Bauteile in speziellen Fraktionen.

Graphite as a naturally occurring crystalline carbon is required for many different applications such as batteries, refractories, electrical products, pencils, etc. Many new graphite deposits are currently being extracted to help meet the growing demand. It is among the list of critical raw materials by the European Union. Graphite ore is mostly beneficiated using flotation separation techniques. The increasing demand for high grade graphite products with up to 99.99% carbon has led to develop various methods to remove impurities even to ppm range. This paper considers separation and purification techniques that are currently employed for graphite mineral beneficiation and identifies areas in need of further research.

Material examined — Three specimens (two females and one male): Ec-1 (1.IV.2009, collected by F. Marian). Three specimens (one female and two males): Ec-1 (1.X.2008, collected by F. Marian). Remarks — Ecuadorian specimens of Monoschelobates parvus are similar in general appearance to Brazilian specimens (Balogh and Mahunka 1969; Balogh and Balogh 1990), but there is a clear difference: prolamellar lines present versus absent in Brazilian specimens. Sometimes presence or absence of prolamellar lines or their partial development can vary in specimens of one species in Scheloribatidae: for example, prolamellar lines in Scheloribates fimbriatus Thor, 1930 - present (see Subbotina 1978), developed partially (Mahunka 1987), indistinctly visible or absent (data of first author, based on specimens from Western Europe); similar situation is known for Scheloribates (Bischeloribates) mahunkai Subías, 2010 (Ermilov 2013).

Sandmann. Type deposition ��� The holotype is deposited in the collection of the Zoological Institute of the Russian Academy of Sciences, St. Petersburg, Russia; two paratypes are deposited in the collection of the Siberian Zoological Museum, Novosibirsk, Russia; three paratypes are in the personal collection of the first author. Etymology ��� The specific name " hemileiformis " refers to the similarity of the new species to representatives of the subgenus Scheloribates (Hemileius) Berlese, 1916. Remarks ��� Monoschelobates hemileiformis n. sp. can be distinguished from the type species, M. parvus Balogh and Mahunka, 1969 (see Balogh and Mahunka 1969) known from Brazil by the larger body size (448 ��� 498 x 265 ��� 282 versus 254 ��� 279 x 147 ��� 162 in M. parvus), long interlamellar setae, which are considerably longer than lamellar setae (interlamellar and lamellar setae similar in length in M. parvus), well developed notogastral and anogenital setae (minute in M. parvus), and presence of aggenital setae (absent in M. parvus). Roman letters refer to normal setae (e to famulus); Greek letters to solenidia; d �� and d �� ��� solenidion and seta coupled. Single prime (��) marks setae on anterior and double prime (��) setae on posterior side of the given leg segment. Parentheses refer to a pair of setae. P��rez-&dblac;��igo and Baggio (1991) described the second species of the genus Monoschelobates, M. translamellatus P��rez-&dblac;��igo and Baggio, 1991 from Brazil. However, this species clearly differs from the type and the present new species by the presence of well-developed pteromorphs (absent or very small ��� generic character in Monoschelobates). Hence, in our opinion, Monoschelobates translamellatus should be included in the genus Perscheloribates Hammer, 1973. Due to the combination of generic characters (in particular, rudimentary pteromorphs, four pairs of sacculi, ten pairs of short notogastral setae, four pairs of genital setae), the species of the genus Monoschelobates are similar to species of the subgenus Scheloribates (Hemileius). Only a single main difference is monodactylous leg tarsi in Monoschelobates versus tridactylous in Scheloribates (Hemileius). Also, the type species of Monoschelobates, M. parvus, is without aggenital setae. Presence or absence of aggenital setae, and variation in numbers of leg claws are not apomorphic characters, therefore it can be used as subgeneric characters. Hence, possibly, Monoschelobates parvus and M. hemileiformis n. sp. should be included in the subgenus Scheloribates (Hemileius).

Quantitative mineralogy done by automated image acquisition, signal processing and analysis became the principle driving force behind geometallurgical research projects and industrial applications. The same analytical methodology is used in forensic examinations, as well as for petrological, mineralogical and archaeometrical studies. Recent developments in instrumental techniques, new algorithms for image and signal processing and growing computing power form the basis for this enormous development. The level of automation, the reproducibility and 'superhuman' never-tiring endurance have made this methodology virtually indispensable. As a consequence of this development, due to the growing economic impact and foreseeable individual consequences as the result of forensic studies, laboratories using automated quantitative mineralogical methods have to face more and more question relating to: • the accuracy and trueness of measurement, • measurement precision and measurement reproducibility, and • metrological traceability. The routine usage of reference materials (RM) is one of the cornerstones to meet such requirements. The principle of measurement is the combined detection of back-scattered electron intensities and X-ray spectra, both depending basically on chemical properties of the material studied. Automated quantitative mineralogy is consequently no true (primary) phase analytical method (PAM) and has to be traced back to primary PAMs. To identify the RMs needed the quantitative mineralogical measurement needs to be separated into distinct steps and tangible variables that influence the success of these steps. The main steps, excluding sampling, are: 1. sample preparation, 2. image acquisition, 3. X-ray spectra acquisition, 4. X-ray spectra processing, 5. image processing including stereological reconstruction of 3-D features, 6. calculation of derived data like mineral mode, particle size distribution, particle shapes, degree of liberation or the resolution of intergrowth relationships. In general, quality management for steps 2 and 3 is well established and described in standardized procedures and well covered with RMs. However, the lack of suitable RMs affects all the other steps significantly. The largest contribution to the uncertainty budget is sample preparation. The preparation of “in-house” standards will improve the situation, but will not reach the effects of future RMs. RMs to assess the correct and reproducible processing of X-ray spectra and the stereological reconstruction are easier to define and fabricable, but very scarce. The experience of the Freiberg Geometallurgy Laboratory with missing suitable RMs is illustrated and missing inter-laboratory comparability of results is identified as the most serious challenge. First approaches to a solution, focusing on the creation of “in-house” standards as a first step towards a broader approach involving other laboratories worldwide, are presented and critically evaluated.
