MULTILEVEL PLANT FOR RECOVERY OF VALUABLE MINERALS Russian patent published in 2002 - IPC

FIELD: beneficiation of mineral resources. SUBSTANCE: invention is related to processes of extraction of mineral resources from ores and placers by gravitational method of dynamic type in thin multilayer flows in equipment combining principle of enrichment on customary concentration tables and on rotating tables with boosting of technology of rendering industrial product harmless. This multilevel plant for recovery of valuable minerals is fitted with system rendering industrial product harmless. Decks of system are made in the form of sectors and are mounted with displacement above chutes for high-density fraction at each level. Chutes for intake of high-density fraction are installed over inner perimeter of plant at several levels with inclination of bottoms towards point of unloading of high-density fraction. Chute for intake of low-density fraction is mounted over outer perimeter of plant with inclination of bottom towards point of unloading of low-density fraction from plant. Drive is mounted for synchronous rotation of distributor of system supplying pulp and water to wash decks. EFFECT: increased intensity of recovery of valuable minerals, reduced toxicity of industrial products of process. 3 dwg
