A survey of studies on the electrodeposition of antimony for refining and extracting it from ores and different types of waste products is given. the results of experiments using chloridic, tartaric and sulpho-tartaric, fluoridic and sulpho-fluoridic solutions are illustrated and discussed. experiments on the lixivation of s62s3, with na2s solutions and on deposition from the solutions.
Antimonial dust is a by-product of lead smelting and an important material for extracting antimony. a new pyrometallurgical process for producing antimony white from the antimonial dust is reported. the process mainly consists of three steps, which are reduction smelting, alkaline refining, and blowing oxidation. first, the reduction smelting of antimonial dust is carried out in an oxygen-rich.
