    摘要:

    湿法炼锑工艺所产出的阴极锑含有铁、砷、铅、硫等杂质,其含锑品位和纯度难以达到商品锑的品位,需要对其进行精炼。目前工业上对锑的精炼包括火法精炼和水溶液电解精炼。所产粗锑杂质较多且富含有大量的贵金属金、银,需要在除杂提纯的同时使金、银等有价金属富集并得到回收,采用水溶液电解能够实现这一目的。由于锑的特殊物理化学性质,这一过程需要考虑粗锑的熔铸过程所采用的设备材质和电解精炼所选用的电解体系。

    Abstract:

    The antimony cathode produced by the antimony hydrometallurgical process contains impurities such as iron, arsenic, lead, and sulfur, and it is difficult for the grade and purity of antimony to reach a level that’s commercially viable, hence the antimony needs refining. The current industrial refining of antimony includes pyrorefining and aqueous electrolytic refining. The crude antimony produced has many impurities and is rich in a large amount of precious metals like gold and silver. Therefore, it is necessary to enrich and recover valuable metals such as gold and silver while removing impurities for purifying antimony. The application of aqueous electrolysis can achieve this purpose. Due to the special physical and chemical properties of antimony, attention should be paid to equipment material used in the melting and casting process of crude antimony and the electrolytic system selected for electrolytic refining.
