Relation to Mining. Antimony rarely occurs in its native metallic form in nature. It easily combines with other elements, usually including sulfur, to form over 100 different minerals. Of these minerals, only stibnite …

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.

Many countries will have to rely on recovering antimony from refractory ores and metallurgical residues. For the purpose of efficient and selective antimony recovery with minimal economic cost and environmental impact, researchers proposed various …
