摘　　要：研究了采用氧化焙烧—浓硫酸强化浸出工艺从钼镍矿中回收钼和镍。试验结果表明:钼镍矿氧化焙烧最佳温度为700℃,最佳焙烧时间2h;氧化焙砂在V(浓硫酸)/m(焙砂)=2mL/g、温度150℃条件下浸出3h,钼、镍浸出率分别为96.4%和85.6%。Oxidation roasting‐concentrated sulfuric acid strengthening leaching process is applied to recovery molybdenum and nickel from Mo‐Ni ore .The optimum conditions of oxidation roasting are that roasting temperature of 700 ℃ ,roasting time of 2 hours .T he roated product is leached under the conditions of V （concentrated sulfuric acid）/m（calcine）=2 mL/g ,temperature of 150 ℃ ,roasting time of 3 hours .The leaching rates of molybdenum and nickel are 96 .4% and 85 .6% ,respectively .
