METHOD FOR CYANIDE SOLUTIONS PURIFICATION FROM NONFERROUS METALS COMPLEXES PRIOR TO SORPTION Russian patent published in 2017 - IPC C22B11/08 C22B3/44 C02F1/58 C02F101/18

Abstract RU 2611237 C1

FIELD: chemistry.

SUBSTANCE: method comprises cyanide solutions treatment with calcium hypochlorite in a concentration of 4.5 to 5 g/l to ensure translation of nonferrous metals to an insoluble precipitate, and exposure for 2-5 hours after precipitation, maintaining the pH of 9.5 to 10.7.

EFFECT: shortened gold sorption from solutions after cyanidation.
