TREATING METHOD FOR HARMFULLESSNESS AND RECYCLING OF MINE TAILINGS ON SCHEELITE ORE

摘要

PURPOSE: Provided is a treatment method of mine tailings to eliminate hazardous material and recycle non-hazardous and non-metallic minerals by an advanced separation process. CONSTITUTION: The method comprises the steps of homogeneously mixing mine tailings of tungsten mine using a mixer, producing ore solution by inputting the mine tailings and water into a reactor, filtering the ore solution using a screen to eliminate various foreign matters, separating the ore solution to metallic ore and non-metallic minerals using a spiral specific gravity separator, thickening and dehydrating the non-metallic minerals with low specific gravity, thereby producing a cake, drying the cake using a rotary drier, crushing the dried cake using a hammer crusher with screen, separating the crushed minerals to fine grains and coarse grains using a micron-separator, and separating the coarse grains to a magnetism minerals and non-magnetism minerals using a magnetic separator.
