摘　　要：某含滑石低品位铜镍矿有用矿物共生关系密切且嵌布不均匀,滑石等层状硅酸盐矿物含量高而易泥化,分选难度较大。通过系统的工艺矿物学研究和探索试验,针对含镍0.78%,铜0.16%的原矿,最终采用滑石、铜镍等可浮—铜镍分离浮选—尾矿强化回收镍的试验流程,试验获得铜精矿含铜24.41%、铜回收率47.50%,镍精矿含镍8.20%、镍回收率77.43%的选别指标。试验获得的技术指标稳定可靠,可以作为矿山开发利用的初步依据。Minerals in a low - grade copper - nickel polymetallic sulfide ore are closely associated with each other and disseminated unevenly , talc and other layered silicate are in high content and they are easy to slime, which results in sorting difficult. For this raw ore containing 0.78% of Ni and 0. 16% of Cu, through systematical mineralogical study and flotation experiments, the test process of talc and copper - nickel iso - flotation, copper - nickel separation flotation and enhanced recovery of Ni in tailings were carried out. Then copper concentrate with Cu grade of 24.41% at an 47.50% recovery, nickel concentrate with Ni grade of 8.20% at an 77.43% recovery were ob- tained. The technical indicators can be used as a preliminary basis for mining exploitation.
