摘　　要：沉积型黑色页岩系钼镍矿是一种组成复杂的细粒高碳多金属伴生硫化矿。在掌握矿石性质的基础上,进行大量选矿试验研究,提出强化浮选—粗精矿加氧化剂充气强氧化—强碱抑制硫化矿反浮选脱碳工艺流程,最终确定最佳高锰酸钾用量1500 g/t,石灰用量15 kg/t,充气时间30 min,脱碳率为47.77%。This sedimentary black shale Ni-Mo ore is a type of complex fine-grained high-carbon multi-metal sulfide ore. According to the ore properties, and on the basis of a large number of ore-dressing tests, a processing flowsheet of intensified flotation followed by rough-concentrate oxidation and decarbonization by a reverse flotation under strong alkali condition to inhibit sulfide minerals was put forward, the optimal operating parameters being po- tassium permanganate dosage 1500 g/t, lime dosages 15 kg/t and aeration conditioning time 30 minutes. The decar- bonization rate of 47.77% was obtained.
