PROCESSING METHOD OF SLURRIES OF GALVANIC PRODUCTIONS Russian patent published in 2010 - IPC C22B7/00 C22B1/00 C22B3/06 C22B15/00 

Abstract RU 2404270 C1

FIELD: metallurgy.

SUBSTANCE: method involves mixing of slurries with additions, crushing, heat treatment, leaching, filtration and extraction of heavy metals from solution. Mixing is performed at crushing with method of mechanical-chemical activation with additions in the form of compounds containing chloride- or sulphate ions in ratio of chloride- or sulphate ions to sum of metals included in slurry of not less than 1:1. Heat treatment is performed at 550-600°C. Further leaching of obtained sinter is performed with acid waste water of galvanic production with similar composition as to content of ions of heavy metals at pH ≤ 3. Extraction of heavy metals from obtained solution is performed with floatation at pH=8-12.

EFFECT: improving environmental situation owing to reducing the burning temperature, and utilisation of heavy metals for the purpose of their further use.
