This article systematically summarizes the characteristics and the properties of lead-zinc oxide ore resources.This paper summarizes the research status of beneficiation technology of high-sludge lead-zinc ores from three aspects:pre-desliming flotation,adding dispersant flotation and carrier flotation.The development of flotation technology was reviewed from the aspects of inhibition of slime by addition dispersant (sodium hexametaphosphate,water glass,etc.) and sulfide-amine method.In addition,the carrier flotation process with great development foreground was introduced (Including conventional carrier flotation and autogenous carrier flotation).%本文系统的概述了氧化铅锌矿石资源的特点及矿石性质.分别从预先脱泥浮选、添加分散剂浮选和载体浮选三方面总结了高泥氧化铅锌矿石的选矿工艺研究现状,从添加分散剂(六偏磷酸钠、水玻璃等)抑制矿泥、硫化-胺法等方面详述了浮选工艺的研究进展;此外,还进一步介绍了具有很大开发前景的载体浮选工艺(包括常规载体浮选和自生载体浮选).
