Dynamic material flow analysis of antimony resources in China
2023年10月1日 Antimony is a hard, lustrous, silvery-grey metal. Antimony is unevenly distributed throughout the crust of the Earth, with China (32%), Russia (23%) and Bolivia (21%) as the top three countries in terms of their antimony reserves (Ding et al., 2021).It is extremely difficult to beneficiate antimony since the average abundance of antimony is only about 2–5

METHODS FOR PROCESSING OF ANTIMONY-CONTAINING
remove antimony from ores and concentrates containing gold. The use of one or another method of processing antimony-containing ores and concentrates depends on the antimony content in them and its form of location (Table 1). Antimony metallurgy is intended for the production of metallic antimony by pyrometallurgical and hydrometallurgical methods.

Antimony Recovery from End-of-Life Products and Industrial
2016年2月8日 The history of antimony goes back to as early as 3100 BC, when it was used by the Egyptians as cosmetic in the form of black Sb 2 S 3 [].Antimony was later used by alchemists in the form of antimony oxychloride SbOCl, which acted as a powerful emetic and thus became known as “mercury of life” or “algarot” [].The etymology of the current name “antimony” is still
