新型捕收剂在青海某混合铅锌矿分选中的应用

Experimental Research on Mineral Processing of Lead-zinc Ore in Qinghai Province

摘要: 对青海某硫氧混合铅锌矿进行了工艺流程及药剂制度试验研究。根据矿石特点，采用先浮铅后浮锌的优先浮选工艺进行试验，选锌工艺采用同时捕收硫化锌矿物和氧化锌矿物的新型捕收剂TY，最终获得了铅精矿铅品位66.39%、回收率97.13%、锌含量0.54%，锌精矿锌品位53.11%、回收率89.23%、铅含量0.65%的浮选指标。该研究为混合铅锌矿的浮选分离提供了一定的借鉴参考意义。

Abstract: The process flowsheet and the reagent system test were carried out for a mixed lead-zinc ore in Qinghai. Aiming at the characteristics of easy muddying of dolomite and illite in the gangue minerals of the sulfide-Oxidized Pb-Zn mixed ores, the process flowsheet of lead and zinc preferential flotation and a new collector TY that can simultaneously collecting Zinc sulfide minerals and Zinc oxidized minerals was adopted. A lead concentrate contenting Pb 66.39%(Zn 0.54%) with recovery is 97.13% and a zinc concentrate contenting Zn 53.11%(Pb 0.65%) with the recovery is 89.23% can be obtained.
