西藏玉龙铜矿I号矿体硫化矿含次生铜较高、含有较多的云母及黏土类矿物，矿石性质复杂；同时，原矿含金、银品位较低，难以使贵金属在精矿中富集。通过使用高效选择性捕收剂BK402，强化金、银的捕收，取得了较好的选矿指标。在小型试验的基础上，进行了选矿扩大连续试验，采用铜钼混合浮选‐强化金银回收工艺流程，经一粗两扫两精作业，扩大试验获得平均班指标为：铜钼混合精矿铜品位29.84％，铜回收率89．38％；钼品位0．51％，钼回收率78．86％；铜钼混合精矿中含 Au 1．26g／t ，含 Ag 58.87g／t ，Au的回收率为29．30％，Ag的回收率为56．93％。
西藏玉龍銅礦I號礦體硫化礦含次生銅較高、含有較多的雲母及黏土類礦物，礦石性質複雜；同時，原礦含金、銀品位較低，難以使貴金屬在精礦中富集。通過使用高效選擇性捕收劑BK402，彊化金、銀的捕收，取得瞭較好的選礦指標。在小型試驗的基礎上，進行瞭選礦擴大連續試驗，採用銅鉬混閤浮選‐彊化金銀迴收工藝流程，經一粗兩掃兩精作業，擴大試驗穫得平均班指標為：銅鉬混閤精礦銅品位29.84％，銅迴收率89．38％；鉬品位0．51％，鉬迴收率78．86％；銅鉬混閤精礦中含 Au 1．26g／t ，含 Ag 58.87g／t ，Au的迴收率為29．30％，Ag的迴收率為56．93％。

With high contain of secondary copper ,much mica and clay ,the ore property is very complex .On the other hand ,there is very low grade of gold and silver ,and the precious metal is hard to be collected in concentrate .The good flotation index was achieved with highly selective collector BK402 .And also the gold and silver were forced to be collected in final flotation production .Based on research ,the pilot test was carried out by Cu‐Mo bulk flotation‐strengthening collecting Au &Ag technology with one roughing‐two scavenging‐two cleaning .The average index of pilot test is:the concentrate with the grade and recovery of copper is 29 .84% and 89 .38% separately ,the grade and recovery of molybdenum is 0 .51% and 78 .86% .and also there is gold with 1 .26g/t and silver with 58 .87g/t ,the recovery of gold and silver is 29.30% and 56 .93% respectively .
