某铜铅锌多金属硫化矿石的浮选试验
|
摘要
某铜铅锌多金属硫化矿石中的有用金属矿物主要为方铅矿、闪锌矿、黄铜矿,其次是斑铜矿、蓝铜矿、异极矿和铅矾等,为了确定铜铅锌回收工艺,进行了选矿试验。结果表明,矿石在磨矿细度为-0.074 mm占75%的情况下,采用1粗3精2扫铜铅混浮、1粗3精2扫铜铅分离、1粗2精1扫选锌流程处理矿石,可获得铜品位为22.13%、铜回收率为80.08%的铜精矿,铅品位为62.32%、铅回收率为79.63%的铅精矿,以及锌品位为52.56%、锌回收率为82.20%的锌精矿。在铜铅分离过程中,无氰无铬环保型铅组合抑制剂CHP的使用是实现铜、铅高效分离的关键。
Useful metal minerals in a copper-lead-zinc polymetallic sulfide ore are mainly galena,sphalerite and chalcopyrite,followed by bornite,azurite,hemimorphite,anglesite and so on. Mineral processing tests were carried out in order to determine the technological process for recovering copper,lead and zinc. The results showed that one-roughing,three-cleaning and two-scavenging for copper-lead mixed flotation,one-roughing,three-cleaning and two-scavenging for copper-lead separation flotation,one-roughing,two-cleaning and one-scavenging for zinc flotation were adopted when the grinding fineness is 0.074 mm accounted for 75%. The copper concentrate with copper grade of 22.13% and copper recovery of 80.08%,lead concentrate with lead grade of 62.32% and lead recovery of 79.63%,zinc concentrate with zinc grade of 52.56% and zinc recovery of 82.20% were obtained. In the process of copper and lead separation,CHP,an environment-friendly lead combined inhibitor without cyanide or chromium,is the key to realize the efficient separation of copper and lead.
