中文摘要: 以四川某蛇纹石为原料,考察添加剂对还原与磁选富集镍铁的影响。结果表明,加入硫酸盐和碳酸盐各15%在1 100 ℃还原120 min,然后在磁场强度79.62 kA/m条件下磁选,精矿中镍和铁品位分别为5.99%和53.84%,镍和铁的回收率分别达到87.59%和72.09%。

Abstract:The effects of additive on ferronickel enrichment from serpentine by reduction roasting and magnetic separation were investigated. The results show that nickel and iron grade in magnetic separation concentrate is 5.99% and 53.84% respectively with recovery of 87.59% and 72.09% respectively under the optimum conditions including dosage of sulfate and carbonate both of 15%, reduction temperature of 1 100 ℃, reduction time of 120 min, and magnetic separation with magnetic field intensity of 79.62 kA/m.
