METHOD OF EXTRACTION OF THE FINE GRAINS OF A USEFUL COMPONENT AT DEVELOPMENT OF SANDS OF CLAY DEPOSITS AND BOULDER OXIDE ORES Russian patent published in 2004 - IPC

Abstract RU 2223824 C1

FIELD: metal mining industry. SUBSTANCE: the invention presents a method of extraction of fine grains of a useful component at development of sands of clay deposits and boulder oxide ores and is dealt with preparation of metal-bearing sands for dressing by the gravitational methods. It is intended for a source material washing at development of minerals of gravel deposits and barks of weathering. The method of extraction of fine grains of a useful component at development of sands of clay deposits and boulder oxide ores provides for washing, disintegration, supply of a pulp in a sluice of deep filling up, a gravity concentration in sluices of deep filling up, a screen sizing, a gravity concentration in sluices of shallow filling up, the concentrate washout from trapping surfaces of deep and shallow filling up, as well as its refining up to the placer metal. At that the pulp before its feeding into a sluice of deep filling up in the bin of hydrobuddling is exposed to treatment with machining ozone-air mixture. EFFECT: the allows to increase efficiency of extraction of fine grains of a useful component. 2 cl, 2 ex
