某复杂多金属矿含有铜、银、铅、锌等多种有用组分，具有较高经济价值。为综合回收有用金属，采用优先浮选工艺，先混合浮选铜铅，再抑铅浮铜，银随铜进入铜精矿产品。原矿含铜0．58％，含银163．82 g／t，最终获得铜精矿含铜17．05％、铜回收率为77?62％，含银5623．6 g／t，银回收率90．25％，有效实现了铜及银的回收。
某複雜多金屬礦含有銅、銀、鉛、鋅等多種有用組分，具有較高經濟價值。為綜閤迴收有用金屬，採用優先浮選工藝，先混閤浮選銅鉛，再抑鉛浮銅，銀隨銅進入銅精礦產品。原礦含銅0．58％，含銀163．82 g／t，最終穫得銅精礦含銅17．05％、銅迴收率為77?62％，含銀5623．6 g／t，銀迴收率90．25％，有效實現瞭銅及銀的迴收。

Beneficiation technique for some complex polymetallic ore containing valuable components such as Cu, Ag, Pb and Zn was studied. A preferential flotation flowsheet was used, including sequentially a Cu?Pb bulk flotation and a preferential separation of copper by depressing lead, with the silver minerals enriched into copper concentrate. With the run?of?mine ore containing 0.58% Cu and 163.82 g/t Ag, the final copper concentrate was obtained at grade of 17.05%Cu and 5 623.6 g/t Ag, with recoveries of 77.62% Cu and 90.25% Ag, realizing an efficient recovery of copper and silver.
