Abstract

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 metal commercial products, a su bstantial decrease in material and energy costs due to increased productivity and f acilitated regeneration of anion-exchange resins.
