摘　　要：广西某氧化铅锌矿含铅锌达4.76%和1.54%,伴生金属银达91g/t,具有较高的回收利用价值。针对矿石性质,对该矿进行了选矿研究,采用优先浮选硫化铅后、加温硫化浮选氧化铅,取得了较好的选矿指标,并综合回收伴生银,。实验室闭路试验得到了铅品位51.13%、铅回收率为78.12%的铅精矿。铅精矿含银1036g/t、银回收率81.12%,为该选矿厂建厂提供设计依据。A lead-zinc oxided ore in Guangxi containing 4.76% and 1.54% of lead and zinc was associated with 91g/t of silver,which has a high recycling value. Directed at the ore properties, research on mineral processing was carried on adopting preferential flotation of lead oxide first, then flotation sulfide by heating sulfrization. Good separation indexes were obtained and the associated silver was recovered. The laboratory closed-circuit test obtained a lead concentrate with the Pb grade of 51.13% and its recovery of 78.12% ,among which it contains 1036g/t of silver and its recovery of 81.12%, which provides the design basis for the construction of the mineral processing factory.
