摘　　要：本试验研究所用矿物来自印尼某矿业公司自有矿山,该矿山含有储量丰富的高氧化铝含镍铁矿和高氧化铝含铬铁矿,出产的原矿含铁量47%~49%,含三氧化二铝约7%~10%,并含有一定量的镍和铬等其它有价成分,具有一定的开采和利用价值。通过混合物料的干燥试验、还原焙烧试验找出研究所用镍矿的高效冶炼方法,研究表明,采用RKEF技术处理印尼样矿与硅镁型镍红土矿1∶1比例的混合物料,在技术上是可行的,在合适的还原焙烧条件下,合金镍品位达到4±1%,炉渣含镍均值为0.06%左右,镍回收率可达95%左右,炉渣含铁均值为6.0%左右,铁的回收率可达90%左右。The mines in this experiment are owned by a mining company of Indonesia, with the high alumina containing nickel iron and high alumina chromium iron. Because of containing Fe 47% ~ 49%, containing Al2O3 about 7% - 10%, and containing a certain amount of nickel and chromium and other valuable com- ponents, the ore has certain exploitation and utilization value. By drying experiment mixing of materials, reduction roasting test to find out the institute by high nickel ore smelting method, research shows, adop- tion RKEF technology for process in Indonesia samples and nickel laterite ore attapulgite 1：1 ratio of mixed materials. The results of the experiment proves the possibility in technique. Under the suitable re- duction roasting, alloy of nickel grade is 4 ± 1%, nickel slag mean about 0.06 %, nickel recovery is 95 %, iron slag about 6.0%, iron recovery of up to about 90 %.
