Antimony Recovery from End-of-Life Products and Industrial … Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3).

Antimony-rich gold ores are the ultimate challenge for gold recovery. Unlike other refractory ores, stibnite doesn’t just trap gold—it actively sabotages extraction, forming chemical barriers that block leaching and foul up solutions. Learn why these ores are gold’s toughest companions and what makes them so uniquely difficult to crack.

Oxidation roasting is often used in sulfide ore smelting. It is used to remove the sulfur ore, arsenic, antimony, and other harmful impurities in ore. In oxidation roasting, the sulfide ore is first decomposed into low-valence sulfide and sulfur, and then the oxide is formed. The oxidation roasting of some sulfide ores is exothermic.
