摘　　要：为了高效利用赞比亚镍矿资源,减少易于泥化的矿物对后续工艺的影响,针对赞比亚低品位硫化镍矿进行了浮选脱泥—粗选与不脱泥浮选的对比试验。得到浮选脱泥—粗选的精矿品位和回收率分别高于不脱泥浮选0.28%和3.62%,从质量和数量两方面都说明了浮选脱泥—粗选工艺好于不脱泥浮选工艺。并对浮选脱泥—粗选的捕收剂进行优化试验,得到了最佳的煤油用量为10 g/t。In order to realize highly efficient utilization of Zambia nickel ore resources and reduce slime minerals which can effect follow-up processing, comparison tests of flotation desliming-rougher and flotation without desliming were conducted. Concentrate grade and recovery of desliming-rougher were 0.28% and 3.62% higher than without desliming respectively. The test results show that desliming-rougher is better than without desliming. Collector optimization test of desliming-rougher showed that the best kerosene dosage was 10 g/t.
