摘　　要：对河北某低品位钴镍矿进行了选矿试验研究,确定采用阶段磨矿、先浮硫化矿、后硫化浮选氧化矿的异步浮选流程,通过组合药剂抑制矿泥、再磨强化硫化效果等手段,最终得到钴品位2.00%、镍品位3.90%的硫化钴镍精矿和钴品位1.47%、镍品位2.73%的氧化钴镍精矿,钴总回收率达到了77.61%,镍总回收率达到了79.20%。实现了钴和镍的初步富集与回收,为钴和镍的进一步提纯奠定了基础。Beneficiation tests were conducted to process the low⁃grade cobalt⁃nickel ore from Hebei Province by adopting an asynchronous flotation flowsheet consisting sequentially of staged grinding,flotation of sulfide minerals and flotation of sulfurized oxide minerals.In the study,combined depressants were used for better depressing of slime,while regrinding process was introduced to intensify the sulfurization effect.Finally,a cobalt⁃nickel sulfide concentrate with Co grade of 2.00%and Ni grade of 3.90%and a cobalt⁃nickel oxide concentrate with Co grade of 1.47%and Ni grade of 2.73%were obtained.The total Co recovery and total Ni recovery reached 77.61%and 79.20%,respectively.In this way,the preliminary enrichment and recovery of Co and Ni resources can be realized,laying a foundation for their further purification.
