METHOD OF WATER TREATING FOR HYDROMETALLURGICAL LEACHING OF ORES AND DRINKING WATER-SUPPLY SYSTEMS Russian patent published in 1997 - IPC

Abstract RU 2095316 C1

FIELD: mining industry and water treatment. SUBSTANCE: invention relates to recovering precious component ions from solutions and to water treatment involving ion- exchange concentration of ions. Novelty consists in that, prior to be submitted to ion exchange, solution undergoes light irradiation, mainly in UV spectrum region, which gives rise to formation of additional hydroxide and hydroxonium ions and hydrogen peroxide and also to suppression of vital activity of pathogen microorganisms, bacteria, and viruses. Thus treated water can be utilized for household and drinking purposes. EFFECT: increased water purification degree. 3 cl
