Antimony Recovery from End-of-Life Products and Industrial Process …
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). The industrial importance of antimony is mainly derived from its use as flame …

Antimony recoveries are normally better than 90%, whereas gold recovery in the gravity separation circuit is only about 40%. The stibnite concentrate normally grades over 60% Sb and less than 0.4% As. The gold concentrate normally grades 3,000 g Au/t; the distribution of gold losses is 40% in tailings and 20% in the stibnite concentrate.
