一、前言云锡焊锡电解阳极泥,含银仅1.8～1.9％,而锡、铅、砷、锑等金属含量皆高达13～25％。但其性质相近,欲回收主要金属银、锡、铋,必须解决锡、银分离以及锡、银、铋和大量砷、铅、锑的分离等问题。鉴于国内尚无处理此种阳极泥同时回收多种金属的生产实践,云锡公司指定第三冶炼厂建立试验装置,由云锡中心试验所协助,从1975年开始,开展处理锡、铅阳极泥的半工 First, the foreword Yun tin electrolytic anode mud, containing only 1.8 to 1.9% silver, and tin, lead, arsenic, antimony and other metal content are as high as 13 to 25%. However, their properties are similar. For the recovery of major metallic silver, tin and bismuth, the separation of tin and silver and the separation of tin, silver, bismuth and arsenic, lead and antimony must be solved. In view of the fact that there is no domestic practice to process such anode slime while recovering a variety of metals at the same time, Yunxi Designated a third smelter to establish a pilot plant, assisted by the Yunnan-Tin Center Laboratory. Since 1975, tin and lead anode mud Half work
