锌窑渣中有价金属综合回收研究现状及展望

Current Status and Prospects of Comprehensive Recovery of Valuable Metals in Zinc Kiln Slag

摘要: 锌窑渣一般富含铜、银、铁、铅、锌、金、铟等多种有价金属，是一种极具回收价值的二次资源。着重介绍了锌窑渣的资源现状以及处理工艺研究现状，并指出了制约锌窑渣综合回收利用的关键所在。同时，作者认为选冶联合工艺是今后锌窑渣处理的主要研究方向，并提出了对综合回收锌窑渣中有价金属的展望。

Abstract: Zinc kiln slag, as a secondary resource with great recovery value, is rich in various valuable metals such as copper, silver, iron, zinc, gold, and indium. This paper reviews the current status of zinc kiln slag resources and treatment technology, and points out the key to restricting the comprehensive recycling of zinc kiln slag. At the same time, the authors hold the opinion that the dressing-metallurgy combination method is the main research direction for the treatment of zinc kiln slag, and the prospect of comprehensive recovery of valuable metals in zinc kiln slag is proposed.
