四川某复杂铜铅锌多金属矿的选矿工艺
Mineral processing technology for a copper-lead-zinc ore in Sichuan
摘要
Abstract
The characteristics of ore are described as a close symbiotic relationship between metal sulfides with uneven disseminated extent at a Cu -Pb -Zn polymetallic deposit in Sichuan,and associated with the mineral processing techniques.To solve the separation of copper,lead and zinc from the ore,the experiment of Cu -Pb-Zn selective flotation technological flowsheet is employed which consisted of grinding fineness,reagents and dosage.The methods in mineral processing,a closed circuit test fhowsheet,included three parts:(1)Twice roughing,one scavenger and four cleaners for flotation of copper;(2)One roughing,one scavenger and four cleaners for flotation of lead; (3)One roughing,one scavenger and three cleaners for flotation of zinc.The experiment indicates that the separation of Cu,Pb and Zn is effectively implemented and made the copper con-centrate containing 22.94%,copper in a 69.71% recovery,lead concentrate containing 51.46%,lead in the recovery of 70.63%,and zinc concentrate containing 45.86%,in a 82.48% recovery.Moreover,fairly good separation indexes obtained by experiments benefit the development and utilization of this type of Cu -Pb -Zn sulfide ore.关键词
