METHOD OF RECOVERY OF VALUABLE COMPONENTS FROM TAILINGS OF ORE CONCENTRATION

摘要

mining industry. SUBSTANCE: supply of tailings to vessel with bottom impervious to liquids and system of collection of productive solution after leaching through pulp line are used for formation from pulp of above-water beach and settling pond. Before pulp discharge, anticipated boundary is determined between formed in fractionation of tailings productive zone with high water permeability and content of valuable component, and unproductive zone in all remaining part of vessel. System of collection of productive solution after leaching of tailings is made in base of productive zone and said solution is used for treatment of tailings of said zone. Dewatering drainage system is made in base of unproductive zone. EFFECT: higher efficiency of recovery of valuable component from tailings with reduced expenditures. 5 cl, 4 dwg
