为了从焙烧的镍钼矿中提取钼和镍，研究了盐酸浸出?硫酸化焙烧和水浸出处理焙烧后镍钼矿的过程。实验结果表明，焙烧的镍钼矿经过盐酸浸出?硫酸化焙烧然后水浸出后能够获得高的钼和镍浸出率。氧化焙烧的镍钼矿添加0.219 mL/g盐酸(12 mol/L)在液固比为3 mL/g的条件下于65°C浸出30 min；浸出渣添加51.9%浓硫酸在240°C下焙烧1 h；焙砂物料采用已经获得的第一段盐酸浸出液在95°C浸出2 h，钼和镍的总浸出率分别达到95.8%和91.3%。
To extract molybdenum and nickel from the roasted Ni?Mo ore, a process of hydrochloric acid leaching, sulphation roasting and water leaching was investigated.The results showed that this processcouldget a high leachingrate of Mo and Ni. Under the optimum conditions of hydrochloric acid leaching (roastedNi?Mo ore leached with 0.219mL/g hydrochloric acid addition at 65°C for 30min with aL/Sratio of 3mL/g), sulphation roasting (51.9% sulfuric acid addition, roasting temperature 240°C for 1h), followed by leaching with the first stage hydrochloric acid leaching solution at 95°C for 2h, the leachingratesof Mo and Ni reached 95.8% and 91.3%, respectively.
