METHOD FOR PROCESSING GOLD-CONTAINING GRAVITY CONCENTRATES OF POLYDISPERSED COMPOSITION

摘要

The invention relates to hydrometallurgy of noble metals and also to methods of carrying out mass-transfer processes in systems solid-liquid and can be used in metallurgical, chemical and other branches of industry. The invention is aimed at enhancement efficiency of leaching process by its intensification. A method of processing gold-containing gravity concentrates of polydispersed composition comprises cyanidation of initial material at pulsed solution feed, wherein the pulsed solution feed is carried out with an additional superposition of harmonic variations of solution flow rate from minimum (zero) to a maximum value, providing transition particles into a suspension state in a layer being processed with frequency of harmonic variations being 1-4 Hz.
