METHOD OF EXTRACTION OF CADMIUM FROM AQUEOUS SOLUTIONS Russian patent published in 1997 - IPC

Abstract RU 2085513 C1

FIELD: chemical technology, inorganic chemistry. SUBSTANCE: method of cadmium extraction involves precipitation with dispersed aluminium in the presence of sodium and ammonium hydroxide taken at mole ratio Cd : NaOH : NH₄OH : Al = 1: (3-9): (72-120):(2.8-4.0), respectively. This ensures to extract cadmium from technological solutions as metallic powder at its purity 95%, not less. EFFECT: complete cadmium extraction. 1 tbl
