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 byproducts. The high purity antimony trichloride may be hydrolyzed to form high purity antimony oxide.
The Sb ore bodies normally occur as veinlets defined by these faults (e.g. the Weizhai and Banpo deposits), or stratiform and lens-shaped ore bodies controlled by anticline and bedding fractures (e.g. the Banian and Jiabai deposits) . Among them, the Weizhai deposit (∼21,000t Sb @ 4.18 wt. %) is hosted in argillaceous limestone and siltstone
