【摘要】：云南水源某铜矿石铜品位为0.88%,56.6%的铜以硫化铜形式存在,43.4%的铜以氧化铜形式存在。矿石矿物组成复杂、泥化现象严重。为给该铜矿石的合理开发利用提供参考,进行了先浮选硫化铜矿物再浮选氧化铜矿物的工艺流程试验。结果表明,在磨矿细度为-200目占80%条件下,以CaO(加入磨机中)和水玻璃为抑制剂、丁黄药为捕收剂经1粗2精硫化铜浮选,硫化铜浮选尾矿经水力旋流器脱泥后,沉砂以硫化钠为活化剂、羟肟酸钠+丁黄药为捕收剂经1粗2精2扫氧化铜浮选,获得的混合铜精矿铜品位为20.13%、回收率为72.81%。氧化铜浮选前经水力旋流器脱泥减轻了矿泥在矿浆中的循环、积累现象,使精矿由四级品提高到三级品,具有较好的经济效益。
[Abstract]:The copper grade of a copper ore in the source of Yunnan Province is 0.88% and 56.6% in the form of copper sulphide. 43.4% of copper exists in the form of copper oxide. The mineral composition of ore is complex and the phenomenon of mudding is serious. In order to provide a reference for the rational development and utilization of the copper ore, the technological process of flotation of copper sulfide mineral and then of copper oxide mineral was carried out. The results show that under the condition of grinding fineness of -200 mesh, Cao and sodium silicate are used as depressants, butylxanthate is used as collector, copper sulphide flotation is carried out by 1 coarse 2 fine copper sulfide, tailings of copper sulphide flotation are deslimed by hydrocyclone. Using sodium sulphide as activator and sodium hydroxamic acid butyl xanthate as collector, the copper grade of mixed copper concentrate is 20.13 and the recovery rate is 72.81. Before flotation of copper oxide by hydrocyclone desliming alleviates the circulation and accumulation of slime in the slurry and improves the concentrate from the fourth grade to the third grade which has good economic benefit.
