中文摘要: 为了实现某氧硫混合型铜矿的高效回收,产出合格的硫化铜精矿和氧化铜精矿。根据矿石性质和浮选工艺特点,采用优先回收可浮性较好的硫化铜矿物,再氧化铜矿硫化后回收的原则流程,分别开展了硫化铜矿和氧化铜矿浮选条件试验,获得了最佳浮选工艺参数。研究结果表明:以丁基黄药和Z-200的组合作为硫化铜捕收剂,以NaHS作为氧化铜矿的硫化剂、戊基黄药作为氧化铜捕收剂,硫化铜矿浮选采用“一粗、两扫、二精”的选别流程,氧化铜矿浮选采用“一粗、两扫、粗精矿两次精选两次精扫选”的选别流程,可以获得Cu品位为22.72%、Cu回收率为64.12%的硫化铜精矿和Cu品位为25.01%,Cu回收率为20.00%氧化铜精矿,该研究结果为开发同类型的铜矿提供了数据支持和技术参考。
Abstract:In order to achieve efficient recovery of an oxygen-sulfur mixed copper ore, and producing qualified copper sulfide concentrates and copper oxide concentrates. The flotation tests were carried out on a mixed copper ore, combining ore properties and flotation process characteristics. Use principle flowsheet of preferential flotation of copper sulfide ore, then recovery vulcanized copper oxide by the method of flotation. The flotation conditions tests of copper sulfide and copper oxide ore were carried out respectively, and the best flotation process parameters were obtained. The results show that at a combination of butyl xanthate and Z-200 is used as a copper sulfide collector, and NaHS is used as a copper oxide sulfide and amyl xanthate as a copper oxide collector. A copper sulfide concentrate with grade of 22.72% was obtained at a recovery of 64.12% by flotation process of one rougher-two scavenging-three cleaning, and a copper oxide concentrate with grade of 25.10% was obtained at a recovery of 20.00% by flotation process of one rougher-two scavenging and one cleaning-two scavenging of rough concentrate. The test results provide powerful data support and technical reference for the development of similar type copper ore.
