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.
