Antimony Element Facts

The name "antimony" is derived from two Greek words: 'anti' and 'monos' which mean 'not alone.'. The name was given because antimony is rarely found native; it is usually combined with sulfur or with heavier metals such as copper, lead and silver. Antimony was used as a catalyst in CFC production.Web

Antimony | U.S. Geological Survey

The most common antimony ore mineral is stibnite (Sb2 S3 ), but more than 100 other minerals also contain antimony. The presence of antimony in surface waters and groundwaters results primarily from rock weathering, soil runoff, and anthropogenic sources. Global emissions of antimony to the atmosphere average 6,100 metric tons per year.Web

Study on Pre-removal Antimony from Antimony–Gold

Antimony has a negative effect on the gold extraction from antimony–gold concentrate, and it is necessary to remove antimony in advance. For a high calcium low antimony–gold concentrate (Ca–Sb–Au ore), this study proposed to pre-remove antimony using slurry electrolysis in HCl–CaCl 2 system. The results indicated that the optimal …Web
