Reinforcement of the two-stage leaching of laterite ores using surfactants

Peiyu Zhang, Hairui Wang, Jingcheng Hao, Jiwei Cui

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 3,   Pages 562-570 doi: 10.1007/s11705-020-1946-5

Abstract: A two-stage leaching process, namely, high-pressure acid leaching-atmospheric acid leaching, was usedThe leaching ratio of Ni was low because of adsorption and incomplete leaching.In this work, surfactants were used as additives to boost the leaching ratio of Ni.Leaching results showed that stearyl trimethyl ammonium chloride (STAC) apparently increased the leachingKinetics analysis indicated that the leaching process was controlled by chemical reaction.
