>Focus on: Antimony, an Obscure but Vital Critical Mineral
The extraction of antimony involves both underground and surface mining methods, depending on the ore deposit's characteristics. After extraction, the ore undergoes crushing and flotation processes to concentrate the antimony content. The concentrate then goes through a smelting process to produce antimony metal or antimony oxide.
