广西某含银铅锌矿石铅氧化程度很高，各矿物共生关系密切，嵌布粒度较细，泥化较严重，属极难选氧化铅锌矿石。为确定该矿石的开发利用方案，对该矿石进行了选矿试验研究。结果表明，在磨矿细度为-0．074 mm占92%的情况下，采用1粗1扫2精选硫化铅、1粗1扫2精选锌、1粗2扫3精选氧化铅、中矿顺序返回流程，最终可获得铅品位为42．21%、含银1682．67 g/t、铅回收率为41．40%、银回收率为37．28%的硫化铅精矿，锌品位为48．86%、含银242．00 g/t、锌回收率为78．56%、银回收率为21．69%的锌精矿，以及铅品位为48．27%、含银2336．28 g/t、铅回收率为34．80%、银回收率为38．06%的氧化铅精矿，铅总精矿铅品位为44．77%、铅回收率为76．20%、银品位为1959．83 g/t、银回收率为75．34%。试验指标较理想，可作为该矿石开发利用依据。
廣西某含銀鉛鋅礦石鉛氧化程度很高，各礦物共生關繫密切，嵌佈粒度較細，泥化較嚴重，屬極難選氧化鉛鋅礦石。為確定該礦石的開髮利用方案，對該礦石進行瞭選礦試驗研究。結果錶明，在磨礦細度為-0．074 mm佔92%的情況下，採用1粗1掃2精選硫化鉛、1粗1掃2精選鋅、1粗2掃3精選氧化鉛、中礦順序返迴流程，最終可穫得鉛品位為42．21%、含銀1682．67 g/t、鉛迴收率為41．40%、銀迴收率為37．28%的硫化鉛精礦，鋅品位為48．86%、含銀242．00 g/t、鋅迴收率為78．56%、銀迴收率為21．69%的鋅精礦，以及鉛品位為48．27%、含銀2336．28 g/t、鉛迴收率為34．80%、銀迴收率為38．06%的氧化鉛精礦，鉛總精礦鉛品位為44．77%、鉛迴收率為76．20%、銀品位為1959．83 g/t、銀迴收率為75．34%。試驗指標較理想，可作為該礦石開髮利用依據。

There is a silver-bearing lead-zinc ore with high oxidation rate,every mineral are closely associated with each other and fine disseminated, thus serious sliming, belongs to refractory oxidation lead-zinc ore. Beneficiation experiment was conducted in order to exploitation and utilization the ore. The results indicated that under the condition of the grinding fineness-0. 074 mm accounted for 92%,utilize the flow of one roughing-two cleaning-one scavenging to float lead sulfide,one roug-hing-two cleaning-one scavenging to float zinc,and one roughing-three cleaning-two scavenging to float lead oxide,lead sulfide concentrate contain 42. 21% Pb and 1 682. 67 g/t silver,with lead recovery of 41. 40% and silver recovery of 37. 28%,zinc concentrate contain 48. 86% Zn and 242. 00 g/t silver,with zinc recovery of 78. 56% and silver recovery of 21. 69%,lead ox-ide concentrate contain 48. 27% Pb and 2 336. 28 g/t silver,with lead recovery of 34. 80% and silver recovery of 38. 06%, the total lead concentrate contain 44. 77% Pb and 1 959. 83 g/t silver,with lead recovery of 76. 20% and silver recovery of 75. 34%. The test index is relatively proper to be a basis for development and utilization of minerals.
