METHOD OF RECOVERY OF VALUABLE COMPONENTS FROM TAILINGS OF ORE CONCENTRATION Russian patent published in 2001 - IPC

FIELD: 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.
