JPH06322455A - Production of metallic antimony - Google ...

(57) [Summary] [Purpose] Metallic antimony is produced from antimony ores mainly composed of antimony sulfide with high yield and reduced exhaust gas treatment cost. [Structure] Chemical reaction formula Sb 2 S 3 + 3Na 2 CO 3 +6 C = 2Sb + 3Na 2 S + 9CO yields Na 2 CO 3 of 1.1 in stoichiometric equivalent to produce metallic antimony.

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). The industrial importance of antimony is mainly derived from its use as flame retardant in plastics, coatings, and …

Direct sulfide electrolysis extracts metal using less energy

Ores of metals including antimony, copper, nickel, and zinc are often compounds of sulfur. The metals are conventionally extracted by converting the ore into oxides by roasting at high temperatures, during which carbon and sulfur dioxide are emitted. The oxides are then converted to metals by heating them at temperatures over 1000°C.
