METHOD OF PRODUCING COPPER (+2) HYDROXOCHROMATES Russian patent published in 2014 - IPC C01G37/14 C01G3/00 C23F1/46

Abstract RU 2504517 C1

FIELD: chemistry.

SUBSTANCE: invention can be used in inorganic chemistry. The method of producing copper (+2) hydroxochromates involves preparing a reactive aqueous solution containing chromium (+6) and copper (+2), forming a copper (+2) hydroxochromate precipitate and separating said precipitate from the solution. The chromium (+6) source used is a liquid electroplating waste - a spent solution containing chromium (+6), and the copper (+2) source used is a liquid radioelectronic production waste - a spent solution from etching printed-circuit boards and/or a spent solution from copper plating printed-circuit boards.

EFFECT: invention enables to recycle liquid electroplating wastes and printed-circuit board wastes.
