Reactive ion exchange processes of nonferrous metal leaching and dispersion material synthesis

Abstract

Two combining reactive ion exchange processes with the application of cation exchange resins have been considered: the cation resin exchange leaching of metal ions from mineral and technogenic raw materials using cation exchange resin in the form of hydrogen and the anion resin exchange precipitation of metal ions in the insoluble compound form with the application of anion exchange resin in hydroxide and salt forms. The applications of methods are illustrated by examples for selective leaching of metals from its oxides, hydroxides, and silicates, as well as by the synthesis of hydroxides, carbonates, oxalates of nickel, cobalt, and other metals.
