Scandium Extraction from Nickel Processing Waste Using

2019-3-12  Scandium is a rare-earth element. Although it is as abundant in the Earth’s crust as lead, it is rarely concentrated. Therefore, it is obtained as a byproduct when mining other metals or from scrap processing of end-of-life products.1,2,3,4,5,6 Scandium is usually recovered using hydrometallurgical processes that include leaching, precipitation, and solvent extraction.7,8

Optimizing Conditions for Scandium Extraction from

In this study, the optimization of scandium extraction from bauxite residue with sulfuric acid is investigated using Taguchi methodology. Based on previous studies, acid molarity, leaching time, solid/liquid ratio, and reaction temperature were selected as

A novel synergistic extraction system for the recovery of

This study aims to improve stripping performance while enhancing extraction efficiency for scandium. Herein, a novel synergistic extraction system for the recovery of scandium with a mixture of Cyanex923 (A, a mixture of four trialkylphosphine oxides) and N1923 (B, primary amine R 1 R 2 CHNH 2 ) in sulfuric acid medium was put forward.
