Abstract

Two different techniques of integrated ion exchange technology processes were researched. The first is recovery of metals from mineral raw materials, intermediate substances and waste products by cation exchange resins in H-form. The second is synthesis of dispersed materials utilizing anion exchange resins in OH-, CO3- , C2O4-forms. The constants of dissolution (leaching) and precipitation using ion exchange resin were determined. These techniques advantages before traditional leaching and precipitation methods are discussed. Application of methods is illustrated by cases of metal separation from its oxides, hydroxides, sulfides, silicates and synthesis different dispersed materials: cobalt and nickel hydroxides, oxalates, base carbonates and others. Mechanism of these processes and different factors influence on the processes are discussed
