从铜锌硫浮选尾矿中综合回收白钨的试验研究

摘要

This article studies the scheelite recovery and utilization out of the copper zinc sulfur tailings. A flowsheet of sulfur floatation after desulphurization is suggested by series of lab tests. Oleic acid and 731 oxidation paraffin wax soap are used as combination collectors at normal temperature. Through small closed -circuit tests, tungsten concentrates were obtained with WO3 concentrate grade of 66.12 % and tungsten recovery rate of 81.03 %.S%针对某铜锌硫矿区早期丢弃尾矿,造成有价组分白钨的严重浪费,进行白钨综合回收利用的选矿试验研究,通过详细的条件试验确定预先脱硫后白钨浮选的工艺流程和药剂制度.白钨矿浮选采用油酸和731氧化石蜡皂组合捕收剂在常温条件下进行.小型闭路试验获得了白钨精矿钨品位66.12％、钨回收率81.03％的良好试验指标,成功地实现了尾矿中白钨二次资源的回收利用.
