Comprehensive Review on Metallurgical Upgradation
Hydrometallurgical process for nickel sulfide ore was developed in 1970s, which is to transfer valuable metals to liquid phase from solid ore by chemical leaching, and then extracts valuable metals by solvent extraction, chemical precipitation, crystallization, and other means [25,26,27].
