| 摘 要： | 硫化镍和黄铁矿浮选性质相近,常规浮选工艺分离难以获得合格产品。研究亚硫酸钠、腐殖酸钠、生石灰、糊精对墨江低品位硫化镍矿硫化镍与黄铁矿浮选分离的效果。结果表明,糊精、生石灰对硫化镍矿抑制作用强于黄铁矿。精选添加2 500 g/t生石灰和100 g/t糊精,浮选获得含镍2.10%、镍回收率45%的精矿指标,优于糊精和生石灰单独作为抑制剂使用的效果。

| Abstract: | For nickel sulfide and pyrite has similar floatability of Jin Chang low-grade nickel ore, Yunnan Mo Jiang, which leads to nickel sulfide and pyrite separation difficult. This paper studies the sodium sulfite, sodium humate, lime, dextrin on sulfur Mo Jiang low-grade nickel ore nickel sulfide and pyrite flotation separation effect. The results show that the dextrin and lime have stronger inhibition on nickel sulfide ores than pyrite; We gained nickel grade 2.10% and nickel recovery rate 45% concentrate index under the 2500 g/t lime and 100g/t dextrin dosage used in concentration, better than that of only dextrin, lime depressants used. |
