摘要
新疆某铜银多金属硫化矿,矿物组成复杂,矿石中金属矿物主要有自然银、辉银矿、含银黝铜矿、黄铜矿、银黝铜矿、斑铜矿、铜蓝、孔雀石、闪锌矿、方铅矿、黄铁矿、毒砂、磁铁矿、赤铁矿、褐铁矿。非金属矿物主要有绿泥石、石榴子石、方解石、角闪石、石英、长石、金云母等。针对原矿矿石工艺矿物学性质,本试验采用"铜银混合浮选"工艺方案,即采用丁基黄药+丁胺黑药为铜、银矿物浮选捕收剂,2号油做起泡剂,在磨矿细度-200目为92%的情况下混合浮选铜银矿物,采用"一预选一粗两扫三精"获得含铜1.22%、铜回收率93.32%,含银12997.67g/t、银回收率95.29%的铜银混合精矿指标。完成,要在数据上、信息上表现为精确的特点。文章针对测绘新技术在工程测量中的应用展开讨论,并提出合理化建议。
A copper and silver polymetallic sulfide ore, mineral composition complex, the metal minerals mainly include natural silver, argentite, imply copper, chalcopyrite, yinyou copper, Bornite, Covellite, Malachite, sphalerite, galena, pyrite, arsenopyrite, magnetite, hematite, limonite. Non-metal minerals are mainly chlorite, Garnet, calcite, Amphibole, quartz, feldspar, Jin, etc. According to the process mineralogy of the ore, this test adopts＂ copper and silver flotation＂ process, using Butane Yao ＋ dingan as collector, flotation collector of copper and silver minerals, mixed flotation copper and silver minerals with 92 of 92 %. the index of Blend concentrate containing copper bearing g / t and recovery ofag g / t is obtained.
