摘要/Abstract

摘要： 针对广西大厂贫铟锡多金属硫化矿石因磁黄铁矿含量上升，铅锑品位下降，铅锑混浮捕收剂效果差，造成铅锑精矿指标不理想的问题，进行了磁黄铁矿弱磁选—铅锑混浮工艺条件研究。结果表明，磨矿细度为-0.074 mm占46.88%的矿石，经1次磁黄铁矿弱磁选（磁场强度为120 kA/m）后，以丁铵黑药+苯胺黑药+DY为组合捕收剂进行1粗2精2扫铅锑混合浮选，获得了Pb+Sb品位为55.08%，铅、锑回收率分别为93.22%、90.94%，锌含量为4.61%的铅锑混合精矿，与生产现场相比，铅锑混合精矿Pb+Sb的品位提高了2.91个百分点，铅、锑回收率分别提高了7.06、5.13个百分点，锌含量下降了0.58个百分点。因此，组合捕收剂丁铵黑药+苯胺黑药+DY可显著改善铅锑混浮精矿指标。

Abstract: To solve the problems of the low lead-tin concentrate index in Dachang Plant in Guangxi Province resulted from high content of pyrrhotite in lean indium-tin poly-metallic sulfide ore，decrease of lead and stibium grade，and unsatisfied performance in lead-stibium flotation by collector leading to non-ideal lead-stibium concentrate index，the tests of pyrrhotite separation by low intensity magnetic separation，and lead-stibium mixed floatation were conducted to find the optimum conditions.Results indicated that，at the grinding fineness of 46.88% passing 0.074 mm，through one stage low intensity magnetic separation for pyrrhotite(at field intensity of 120 kA/m)，and with butylamine dithiophosphate，amino dithiophophate and DY as combined collector via one roughing-two cleaning-two scavenging lead-stibium bulk flotation，lead-stibium mixed concentrate with Pb+Sb grade of 55.08%，lead recovery of 93.22%，stibium recovery of 90.94%，and 4.61% Zn was obtained.Compared with on-site process，Pb+Sb grade increased by 2.91 percentage points，lead recovery increased by 7.06 percentage points，stibium recovery increased by 5.13 percentage points，zinc content decreased by 0.58 percentage points.The result pronouncedly indicates that the combined agent of butylamine dithiophosphate，amino dithiophophate，and DY is a new high efficient collector of lead-antiomony mixed flotation.
