The waste product from the hydrometallurgical processing of nickel laterite ores can contain valuable metals, making their recovery economically viable. However, the high‐impurities content, mainly iron, makes the process technically unfeasible. As a result, the separation of metals from the leach solution must be selective. Among the techniques available, the use of chelating resin is advantageous...
Extraction of scandium (Sc) from nickel processing residue using Cyanex 923 was studied. Cyanex 923 showed better selectivity for Sc compared with the other metallic components in the residue. Scandium was extracted by solvent extraction via a solvation mechanism. The aqueous-to-organic (A/O) phase ratio was set at 1:2. An increase in the scandium extraction rate was observed when increasing the concentration...
