US3944653A Process for preparing high purity antimony

Antimony sulfide contained in an antimony sulfide bearing ore, such as stibnite, is converted to high purity antimony trichloride by reacting the antimony sulfide bearing ore with a source of chlorine to form high purity antimony trichloride and sulfur or hydrogen sulfide as separable by-products. The high purity antimony trichloride may be hydrolyzed to form high purity antimony oxide.

Antimony oxide can be prepared by two processes, the direct and the indirect process. Indirect process. In this process, antimony metal or ores is melted in a furnace to give ATO vapors. The vapors are quenched with air and cooled to convert the vapor to white powder. These powders are further filtered to give antimony trioxide powder.

The sulphide is removed to leave elemental antimony with scrap iron. Sb 2 S 3 + 3Fe → 2Sb + 3FeS. In antehr process, some ores can be heated to evolve the oxide Sb 2 O 3 and this in turn can be reduced by charcoal in the presence of sodium sulphate, to ensure mixing, to form elemental antimony. 2Sb 2 O 3 +3C → 4Sb + 3CO 2
