针对巴里选厂原矿性质的变化，原矿中铅锑品位下降幅度较大，铅锑精矿质量和回收率较低的问题，进行了提高铅锑精矿质量和回收率的试验研究。本次试验考察了硝酸铅、WJ和GZT用量对铅锑浮选指标的影响。试验研究表明，硝酸铅对铅锑浮选活化效果不显著；黑药与WJ组合对铅锑矿物有较好的捕收效果；精选添加GZ T能有效提高铅锑精矿的质量，最终闭路试验获得了较好的技术指标：铅锑精矿Pb＋Sb品位达到59.99％，（Pb品位为32．92％，Sb品位为27．07％）；铅回收率达95．57％，锑回收率达95.17％。
針對巴裏選廠原礦性質的變化，原礦中鉛銻品位下降幅度較大，鉛銻精礦質量和迴收率較低的問題，進行瞭提高鉛銻精礦質量和迴收率的試驗研究。本次試驗攷察瞭硝痠鉛、WJ和GZT用量對鉛銻浮選指標的影響。試驗研究錶明，硝痠鉛對鉛銻浮選活化效果不顯著；黑藥與WJ組閤對鉛銻礦物有較好的捕收效果；精選添加GZ T能有效提高鉛銻精礦的質量，最終閉路試驗穫得瞭較好的技術指標：鉛銻精礦Pb＋Sb品位達到59.99％，（Pb品位為32．92％，Sb品位為27．07％）；鉛迴收率達95．57％，銻迴收率達95.17％。

The great decline of lead and antimony grade in the raw ore in Bali plant leads to the low grade and recovery of Pb+Sb concentrate .Hence the laboratory experimental research has been carried out to improve the quality and the recovery of Pb+Sb concentrate .The effects of dosage of lead nitrate ,WJ and GZT on lead antimony floatation indexes has been studied .Experimental results indicate that the activation effect of lead nitrate on lead antimony floatation ihes not significant ;the combined ues of thiophosphate and WJ show good collecting ability to lead antimony content ;GZT can effectively improve the grade of Pb+Sb concentrate in the cleaning flotation .In the final closed-circuit test a Pb + Sb concentrate with grade of 59.99% (Pb 32 .92% + Sb 27 .07% ) ,with Pb recovery of 95 .57% and Sb recovery of 95 .17% can be achieved .
