摘要
为了脱除粗锡中的砷、锑、铋杂质,本文研究了一种新的以 CaCl_2——KCl——NaCl 熔融盐为电解质,以粗锡为阴极的电解精炼过程以及影响脱除杂质的各种因素.实验取得了令人满意的结果.
In order to remove arsenic,antimony and bismuth from crude tin,a new process o of electrolytical purification and all the factors of effecting on impurity-removal are discussed in this paper.The process uses the molten salt of Cacl_2-KCl-NaCl as the electrolyte,and crude tin,as cathode.The experiments have bronght about satisfact- ory results.
