Geologists are enlisted by the companies to ...

(e.g., mine tailings, process residues, manufacturing scrap) from the production of lead, copper, gold, and antimony [7]. The large production volumes, especially for copper and lead, mean that these residues have the potential to replace a large portion of the primary antimony production [7]. Secondary antimony sources also include end-of-life

Thus far, only a new chlorine–hydrolysis process has been commercially used by the Hunan Chenzhou Mining Group Co., Ltd. (Hunan Province, China). Fig. 1 shows this new hydrometallurgical process for antimony extraction. This process involves chlorination–oxidation leaching that inhibits the formation of most impurities in solution.

The problem of antimony leaching from a polyethylene terephthalate bottle is very much different from the leaching of antimony from mining wastes. Each process necessitates custom-made treatment methodologies by taking into account various factors including the speciation and concentration. The current review is focused on this aspect.

The purpose of this research was to understand the weathering process and environmental impact of heavy metals and metalloids from the old antimony (Sb) mine sites in Sulzburg. In this study, we examined the mineralogy and whole-rock chemistry and performed soil sequential extraction and water chemical analysis around mine sites.
