Efficient and selective leaching of nickel and cobalt from nickel laterite ore by a combined atmospheric acid leaching-ferric chloride solution leaching process: optimization and mechanism

Abstract

, the leaching efficiencies of Ni, Mn, Co, and Mg were around 90.0%, while the precipitation efficiencies of iron were 89.0% and 90.5% for saprolite and limonite laterite ore, respectively. Efficient and selective leaching of valuable metals from limonite and saprolite laterite ore under mild conditions was thus realized using the proposed process.
