Limonite-type and serpentine-type nickel laterite ores were taken for experiment. A coupled process for extracting nickel and cobalt was adopted, consisting of chloridizing leaching with HCl as the initial leaching medium for limonite-type nickel laterite ore, and selective hydrolysis for serpentine-type nickel laterite ore. The leaching rates of Ni, Co, and Fe from limonite-type laterite ore were 99.6%, 100%, and 96.9% respectively, under the conditions including acid-to-ore ratio of 5∶4, liquid-to-solid ratio of 4∶1, reaction temperature of 100 ℃, and reaction time of 30 min. After that, the obtained lixivium of limonite-type nickel laterite ore, being mixed with concentrated HCl in a volume ratio of 1∶4, was used to leach serpentine-type nickel laterite at 150 ℃ for 90 min with a liquid-to-solid ratio of 1∶1, resulting in the leaching rates of Ni and Co up to 84.9% and 100%.
