The diminishing availability of nickel sulfide ores and the increasing demand for nickel and its compounds have led to a growing interest in laterite deposits as an alternative source for producing nickel. However, extracting nickel from laterite ore

This study was investigated to fabricate nanosized cobalt (Co) powder from cobalt hydroxide Co(OH) 2 recovered from spent lithium ion battery. Direct process newly proposed was attempted to transform phases as follow: Co(OH) 2 → Co 3 O 4 → Co. Th

We studied the separation and recovery of copper(II), nickel(II), cobalt(II), zinc(II), and cadmium(II) from magnesium and calcium, using synergistic solvent extraction (SSX) in a typical hydrometallurgical waste solution. A mixture of Versatic 10 ac
