某红土型镍矿品位控制的研究与讨论

Study and Discussion on Grade Control of a kind of Laterite-type Nickel Ores

红土型镍矿与硫化型镍矿共同支撑着世界范围内经济发展的镍矿需求,其中红土型镍矿的产量占比为60%,硫化型镍矿的产量占比为40%。近年来,随着硫化型镍矿开采速度的加快、勘探工作的放缓,红土型镍矿凭借其成熟的冶炼技术和开采工艺逐渐扩大市场。东南亚地区作为全球红土型镍矿储量最丰富的地区,吸引了大量的镍矿开发商及冶炼厂投资落地。以印尼马鲁古岛东南部某红土型镍矿为研究对象,详细研究了该矿区镍矿的采选配矿品位控制工艺,探讨了造成镍矿品位贫化的原因,对红土型镍矿品位控制进行了研究与讨论,旨在为镍矿开采提效降本提供一定的思路。

Laterite-type nickel ores and sulfide-type nickel ores jointly support the demand for nickel ores in the world's economic development,of which laterite-type nickel ore production accounts for 60%,sulfide-type nickel 40%.In recent years,with the acceleration of sulfide-type nickel ore mining,exploration work slowed down,laterite-type nickel ore with its mature smelting technology and mining technology gradually expanded the market.Southeast Asia,as the region with the richest laterite nickel ore reserves in the world,has attracted a large number of nickel mine developers and smelters to invest.Taking a laterite-type nickel mine in the southeast of Maluku Island,Indonesia,as the research object,this paper studied the ore grade control technology of the mine in detail,and discussed the causes of nickel ore grade depletion,so as to provide some ideas for improving efficiency and reducing cost of nickel ore mining.
