Hydrometallurgical process for the production of antimony |
| abstract |
A hydrometallurgical process for pollution-free recovery of metallic antimony from stibnite and other antimony-containing materials by (a) reduction of ferric chloride by such materials to produce ferric chloride and antimony (III) chloride, (b) recovery of metallic antimony, preferably by electrolysis, (c) regeneration of the ferric chloride, and (d) purge of impurities. Optionally, the metallic antimony thus produced may be subsequently oxidized if desired to produce high purity antimony oxide. The process is amenable to cyclical operation. |
