As for the acid leaching residue of lateritic nickel ore with a TFe grade of 51.38% and S content of 2.01%, a comparative experimental study was carried out for different phase transformation processes. The results show that tests with magnetizing roasting and direct reduction roasting processes generate roasted products containing a wide variety of minerals with complex dissemination characteristics, which is not conducive to subsequent iron-sulfur separation and sorting operations. The lateritic nickel ore, after having been roasted at a hydrogen-rich environment at 900 ℃ for 60 min, is subjected to grinding and magnetic separation, producing a low-sulfur iron concentrate with a TFe grade of 72.50% and a S content of 0.067%. It is concluded that such roasting process at a hydrogen-rich environment can make iron and sulfur effectively separated from each other, which is conducive to subsequent smelting operations.

针对TFe品位51.38%、S含量2.01%的红土镍矿酸浸渣，开展不同矿相转化工艺对比试验研究。结果表明，磁化焙烧与直接还原焙烧试验得到的焙烧产物存在矿物种类繁多、嵌布关系复杂等问题，不利于后续铁硫分离与分选作业；富氢环境、焙烧温度900 ℃、焙烧时间60 min所得焙烧矿经磨矿-磁选，获得了TFe品位72.50%、S含量0.067%的低硫铁精矿。富氢环境下焙烧可有效实现金属铁和硫的高效分离，有利于后续冶炼作业。
