摘    要:四川白玉铜铅锌共生矿矿石性质复杂,铜铅矿物嵌布粒度极细,铜锌矿物致密共生,分离较为困难。采用铜铅部分混合优先浮选-选铅-选锌-铜铅混合精矿加压浸出分离工艺流程,以EM-WB-12为铜矿物捕收剂进行选矿试验,并在选铅时进行了粗精矿再磨,实验室试验可获得Cu+Pb品位28.09%,铜、铅回收率分别为85.00%、53.38%的铜铅混合精矿,铅品位和回收率分别为52.68%、30.13%的铅精矿以及锌品位和回收率分别为52.72%、73.62%的锌精矿,同时伴生银得到了有效回收。对铜铅混合精矿进行加压浸出,取得了Zn浸出率94.36%,Cu浸出率91.21%的优良指标,渣中Pb脱硫后品位达到40%。在此基础上进行了选矿扩大试验,其试验指标较好地验证了实验室试验结果。

关 键 词:铜铅锌共生矿  细粒嵌布  EM-WB-12捕收剂  加压浸出

Abstract:In view of characteristics of close associated relationship with each other and owns complicated ore nature and fine dissemination size of valuable mineral for a copper-lead-zinc sulfide ore in Baiyu, the beneficiation tests were carried out by the process of preferential flotation of copper and lead,lead and zinc, pressure leaching of copper-lead mixed concentrate.And by regrinding rougher lead concentrate, new type special collector EM-WB-12 was added.Then, copper-lead mixed concentrate mixture with Cu and Pb grade of 5.15% and 22.94% at a 85.00% Cu recovery and 53.38% Pb recovery, lead concentrate with Pb grade of 52.68% at a 30.13% recovery were respectively achieved.Also, the associated silver in ores was effectively enriched.Taking pressure leaching to Cu-Pb mixed concentrate, got the leaching rate of Zn at 94.36% and Cu at 91.21%,the grade of Pb ofter dressing at 40%.Based on the tests of laboratory, pilot test were organized, The results fully confirm the reliability of those from laboratory tests.
Keywords:Copper-lead-zinc sulfide ore  Fine-disseminated  EM-WB-12 collector  Pressure leaching
