Study on Gold and Silver Recovery from the As-Cu-Pb Alloy Produced by Copper Dross Smelting with Soda-Lead Concentrate in a Smelter

Chen Hai-qing

Abstract

Soda-Lead concentrates smelting process was put forward according to the characteristics of As-Cu-Pb alloy produced by Copper dross smelting with Soda-Lead concentrate in a smelter.The results show that the recovery of Lead,Gold and Silver are 93.36%,91.02% and 69.38% seperately,and the recovery of Copper in matte is more than 98% when the ratio of Lead concentrate to alloy is 230%.
