Mineral Commodity Report 2 - Antimony

Antimony is obtained from low grade sulphide ores (5–25% Sb) by roasting the ore to form the oxide Sb 2 O 4, which is then reduced to the element by heating with carbon. Higher grade ores (25–40% Sb) are melted with scrap iron in a furnace. The iron combines with the sulphur to form a liquid layer of

Antimony (Sb) | Antimony

Sulfide ore or liquated antimony sulfide is reduced to metal by iron precipitation. Antimony trioxide may be volatilized from sulfide ores, and can be reduced to metal with charcoal in reverberatory furnaces. Antimony product may also be produced by blast furnace smelting or hydrometallurgical methods.

Type metal - Wikipedia

Alchemists had shown that when stibnite, an antimony sulfide ore, was heated with scrap iron, metallic antimony was produced. The typefounder would typically introduce powdered stibnite and horseshoe nails into his crucible to melt lead, tin and antimony into type metal. Both the iron and the sulfides would be rejected in the process.

Stibnite - Wikipedia

Stibnite, sometimes called antimonite, is a sulfide mineral with the formula Sb2S3. This soft grey material crystallizes in an orthorhombic space group. It is the most important source for the metalloid antimony. The name is from the Greek στίβι stibi through the Latin stibium as the old name for the mineral and the element antimony.

Antimony is primarily produced from sulfide ores. It can be also obtained from oxidized ores. The process mainly used is based on sulfide concentrates roasting, which is then followed by antimony oxide reduction with a carbon-containing reducing agent: 2Sb 2 S 3 + 9O 2 = 2Sb 2 O 3 + 6SO 2 (1) Sb 2 O 3
