Paper Title
Research of Conditions for Processing of the Stale Tailings of Pb-Zn Ores of Kazakhstan

Abstract
Investigations of the processing conditions of stale tailings from lead-zinc ore indicate the need to pre-clean the surface of stale tailings from sludge-clay particles and oxidation products. This article considers the possibility of flotation beneficiation of stale tailings in order to maximize the recovery of valuable components in collective product.
