Scientific researches performed as part of grant funding of the project focused on solving a global problem related to saving resources and the environmental protection resulted in the development of an innovation technology of gravity and flotation beneficiation for gold-bearing man-induced sediments of near-surface strata together with allied veined masses within crude ores mined selectively at the West Kalbinsk metallogenic zone in Kazakhstan. Stage separation of a mixture consisting of arsenic carbonaceous man...

It is proposed to process gold mine man-made wastes through ultrasonic activation of source materials in water, then in an alkaline solution with subsequent cyanidation of gold-impregnated cakes, or direct cyan idation and sorption conditioning of gold multicomponent solutions with nano-structured anionite an av erage radius of pores of which is within 600-700 Зє that contains no more than 6-8% of strong-base groups. A preliminary withdrawal of elements accompanying gold ensures obtaining of good- quality target m...
