高含碳锌窑渣中Cu和Ag的综合回收
Recovery of Copper and Silver from High-Carbon-Zinc Kiln Slag
摘要
Abstract
To comprehensively utilize the copper and silver of a zinc kiln slag in Yunnan with copper of 1.47%, silver of 294 g/t, and carbon of 23.12%, we determined the optimum flotation conditions and carried out the closed circuit test. It was difficult to enrich the copper and silver by the single flotation process, so the combined process of carbon flotation-copper flotation-leaching was used to the kiln slag. Finally, the copper concentrate was obtained. The copper grade is 11.83%and the silver grade is 2 616 g/t. The comprehensive recovery rates of copper and silver reach 72.03% and 75.06%, respectively. The use of combined process to the zinc kiln slag breaks through the limitation of single flotation process and greatly improves the grade of copper concentrate.关键词
