Antimony - an overview ScienceDirect Topics
3.2.1 Antimony. Antimony (Sb) is a metalloid that is mainly used in flame retardants, lead-acid batteries, chemicals, and ceramics. Three largest mining world producers of antimony as of 2021 are China, Russia, and Tajikistan (U.S. Geological Survey, 2022).The main sources of antimony are sulfide ores, where Sb occurs as a mineral stibnite (Sb 2 S 3, specific gravity of 4.6 g/cm 3).
