摘　　要：对河南某金银铅锌多金属矿石进行详细的工艺矿物学研究,查清该矿石工艺类型、主要回收目的矿物种类、粒度特征及嵌布特征等,为其制定合理的选别流程及技术条件提供了数据支撑。根据矿石及目的矿物工艺特征,确定了原矿重选—重尾浮选金银铅—金银铅尾浮选锌的选别流程,金、银、铅及锌都得到有效回收。A detailed study was conducted on the process mineralogy of the gold-silver-lead-zinc polymetallic ores in a mine in Henan Province to understand the metallurgical type,main target minerals for recovery,particle size characteristics,and dissemination characteristics,providing data support for the development of a reasonable separation process and technical conditions.Based on the metallurgical characteristics of the ore and target minerals,a separation process was determined as raw ore gravity separation-flotation of gold,silver,and lead from gravity separation tailings-flotation of zinc from gold-silver-lead tailings,resulting in effective recovery of gold,silver,lead,and zinc.
