摘要: 对硫、银、锡含量较高的玻利维亚某重选选锡尾矿进行了有价元素回收的试验研究,确定了以浮选为主、焙烧-氰化为辅的锡、硫、银回收工艺。闭路试验得到了硫品位46.70%、硫回收率97.88%、银品位339 g/t、银回收率73.73%的硫精矿,以及锡品位45.37%、锡回收率52.73%的锡精矿,银的焙烧-氰化作业浸出率为75.10%。

Abstract: Experimental study of valuable elements recovery was done on a gravity separation tin separation tailings which has high content of sulfur, silver and tin in Bolivia, recovery technology of tin, sulfur and silver which took the flotation main, roastingcyanide as subsidiary was confirmed. Sulfur concentrate with sulfur grade 46.70%, recovery rate 97.88%, silver grade 339 g/t,recovery rate 73.73% and tin concentrate with tin grade 45.37%, recovery rate 52.73% were obtained through closed-circuit test, leaching rate of roastingcyanide operation of silver was 75.10%.
