Abstract

Antimony (Sb) concentrations were measured in wet atmospheric deposition at 10 high-elevation sites in the Czech Republic (Central Europe) during three winter seasons (2009-2011). Soluble and insoluble Sb forms were quantified in snow (vertical deposition) and rime (horizontal deposition) on mountain summits located equidistantly near the Czech borders with Austria, Germany and Poland. The highest Sb concentrations were found in the soluble form in rime (0.47 μg L -1 ), while the lowest Sb concentrations were those in the insoluble form in snow (0.017 μg L -1 ). The estimated average Sb deposition rate in Central Europe amounted to 1.3. 10 -4  g m -2 yr -1 . Most Sb was deposited in the soluble form in snow (7.9. 10 -5  g m -2 yr -1 ), followed by the soluble form in rime (3.5. 10 -5  g m -2 yr -1 ). The corresponding insoluble fraction contained less Sb, namely 1.2. 10 -5  g m -2 yr -1 in snow and 2.3. 10 -6  g m -2 yr -1 in rime. The average Sb deposition in Central Europe, measured at an altitude of 1000 m a.s.l., was by six orders of magnitude higher compared to Sb deposition in the Arctic (7. 10 -10  g m -2 yr -1 ), and by four orders of magnitude lower compared to Sb deposition in a Sb-Hg mining district in China (7 g m -2 yr -1 ). Using the HYSPLIT model, backward trajectories of air masses indicated that the Sb sources were predominantly situated in Upper and Lower Silesia., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Ltd.

Abstract

The European spot market for ferro-silicon moved down by almost 7% in the week ended Friday January 27, with the price range narrowing downward by €300 per tonne because there was almost no consumer demand, trade sources said. [ABSTRACT FROM AUTHOR]

Abstract

The demand for 'high-tech' element resources (e.g., rare earth elements, lithium, platinum group elements) has increased with their continued consumption in developed countries and the emergence of developing economies. To provide a sound knowledge base for future generations, it is necessary to identify the spatial distribution of critical elements at a broad-scale, and to delineate areas for follow-up surveys. Subsequently, this knowledge can be used to study possible environmental consequences of the increased use of these resources. In this paper, three critical industrial elements (Sb, W, Li) from low-sampling density geochemical mapping at the continental-scale are presented. The geochemical distribution and spatial patterns have been obtained from agricultural soil samples (Ap-horizon, 0–20 cm; N = 2108 samples) collected at a density of 1 site per 2500 km2 and analysed by ICP-MS after a hot aqua regia digestion as part of the GEMAS (GEochemical Mapping of Agricultural and grazing land Soil) soil-mapping project in 33 European countries. Most of the geochemical maps show exclusively natural background element concentrations with minor, or without, anthropogenic influence. The maximum extent of the last glaciation is marked as a discrete element concentration break, and a distinct difference occurs in element concentration levels between the soil of northern and southern Europe, most likely an effect of soil genesis, age and weathering. The Sb, W and Li concentrations in soil provide a general overview of element spatial distribution in relation to complexity of the underlying bedrock and element mobility in the surface environment at the continental-scale. The chemical composition of agricultural soil represents largely the primary mineralogy of the source bedrock, the effects of pre- and post-depositional chemical weathering, formation of secondary products, such as clays, and element mobility, either by leaching or mineral sorting. Observed geochemical patterns of Li, W and Sb can be often linked with known mineralisation as recorded in the ProMine Mineral Database, where elements in question occur either as main or secondary resources. Anthropogenic impact has only been identified locally, predominantly in the vicinity of large urban agglomerations. Unexplained high element concentrations may potentially indicate new sources for high-tech elements and should be investigated at a more detailed scale. • Sb, W, Li concentration of European soils in aqua regia extraction. • Agricultural soil dataset of Europe (GEMAS) allows studying the large scale variations. • Distribution of Sb, W, Li in European soils is clearly dominated by geology and mineralisation. • Data shed light on the new mineral resources, not detected actually by traditional methods.

Abstract

The price for ammonium paratugnstate (APT) in Europe moved lower in the week ended Friday August 23, weighed down by bearish sentiment ahead of the late-August auction for the entire antimony stock held in the defunct Fanya Metal Exchange. Meanwhile, the Chinese APT export price was stable amid market uncertainty. [ABSTRACT FROM AUTHOR]
