Antimony Recovery from End-of-Life Products and Industrial

高达12%返现 Feb 08, 2016 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 retardant in

WO2007115377A1 Process for recovery of antimony and

A process for recovery of antimony and metal values from antimony- and metal value-bearing materials is provided. A coarse (typically >250-µm) concentrate of the antimony- and metal value-bearing materials is provided. The coarse concentrate is then subjected to a process for selective recovery of antimony in the form of solid antimony or an antimony containing solution.

Oct 01, 2000 Recovery of gold from refractory ores requires a pretreatment to liberate the gold particles from the host mineral. In particular, in the case of stibnite (Sb 2 S 3), the antimony (Sb) forms stable compounds with sodium cyanide (NaCN) during the cyanidation process; as a consequence, cyanide consumption increases.Pretreatment is usually an oxidation step.
