中文摘要:
      原矿铜镍矿物的工艺粒度偏细,在-0.01mm的级别中,黄铜矿、镍黄铁矿以及磁黄铁矿的含量分别为88.57%、93.58%和75.71%,造成铜镍浮选分离时互含较高。试验首先对铜镍混合浮选精矿进行浓缩脱药,然后以石灰和亚硫酸作为镍矿物的组合抑制剂,并用Z-200强化铜矿物可浮性及细颗粒铜矿物的回收,在磨矿细度-0.030mm89.3%的条件下,经过一次粗选、一次扫选和三次精选的闭路浮选,获得了铜品位20.11%、含镍0.67%,铜回收率74.59%的铜精矿;镍品位5.57%、含铜0.60%,镍回收率98.96%的镍精矿,实现了铜镍的有效分离。

      The process grain-size of a copper-nickel ore is superfine.At the level of less than 0.01mm the content of chalcopyrite,pentlandite and pyrrhotite is 88.57%,93.58% and 75.71% respectively,which leads to copper and nickel containing each other seriously.In the experiment reagents were removed from the copper-nickel bulk flotation concentrate first,then CaO and H2SO3 were used as combined depressant and Z-200 was used to strengthen floatability of copper ore and recover its fine particles.When the grinding fi...
