The testing results showed that the optimal reduction conditions are 1320℃ for 120 min and the proportional mass fractions of activated carbon powder and the additive A are 3% and 5%, respectively. The additive A accelerates the aggregation of metallic grains so as to make the enriched metallic grains easier for magnetic separation. The mass fraction of maximum nickel in ferronickel alloy and nickel recovery in the laterite-nickel ore are 8.31% and 95.44%, respectively. Metallic nickel is thus enriched.

研究结果表明，最佳反应条件：还原温度为1320℃，还原时间为120min，还原剂与添加剂的质量分数分别为3%及5%；添加剂可促进金属晶粒的聚集，富集的金属晶粒更易于磁选分离；还原产品镍铁合金中镍的质量分数可达8.31%，矿石中镍的回收率可达95.44%，金属镍得到了富集。

Hydrometallurgy: Extraction of metal from ore by dissolving the metal and then recovering it from the solution.

湿法冶金学：将矿石中的金属溶解，再从溶液中回收金属的提取方法。

The carbonaceous lead zinc ore in Inner Mongolia is very large in reserve,but it contains a high level carbon,which interferes with the selective flotation of these ores,making the selective process target very low and economic benefit poor.In recent years,the decarbonizing technology has been greatly improved that provides enough reliable information to exploit these ores

近年来 ，在内蒙古地区先后发现了几处大型含碳铅锌多金属矿床，但矿石中的高含碳量已成为制约铅锌矿开发利用的主要因素，以至于有些矿床至今未被开发利用，除碳已成为含碳铅锌多金属矿床开发利用的关键由于碳对浮选药剂的选择与消耗、工艺流程的制定和技术经济指标都有显著
