摘要
印尼某铅锌矿石PbO和ZnO品位分别为3.87%、5.72%,铅、锌呈细粒浸染,分别主要以方铅矿、闪锌矿的形式存在,难以分离。为回收利用铅、锌,进行浮选试验。结果表明,采用D82作锌矿物抑制剂,3418A为铅矿物捕收剂,硫酸铜作锌浮选活化剂、丁基黄药作捕收剂,原矿经磨矿(-0.074 mm 82%)—1粗3精2扫优先浮选铅—1粗2精2扫选锌闭路流程选别,可获得铅精矿品位68.23%、回收率83.37%,锌精矿品位56.72%、回收率81.62%的良好指标。
The Pb O and Zn O grade of a lead zinc ore in Indonesia are 3. 87% and 5. 72% respectively. Lead and zinc are fine-grained,mainly exist in the form of galena and sphalerite respectively,which are difficult to separate. In order to recycle lead and zinc,flotation test was conducted. The results showed that using D82 as zinc mineral inhibitor,3418 A as lead mineral collector and copper sulfate as zinc flotation activator,and butyl xanthate as collector,grinding（-0. 074 mm 82%）-one roughing-three cleaning-two scavenging lead preferential flotation lead-one roughing-two cleaning-two scavenging zinc separation closed-circuit process,good indicators with lead concentrate grade of 68. 23%,recovery rate of83. 37%,zinc concentrate grade of 56. 72%,recovery rate of 81. 62% could be obtained.
