LINE FOR CONCENTRATION OF AURIFEROUS SANDS Russian patent published in 1998 - IPC

FIELD: concentration of mineral resources, applicable in processing of sands with fine gold on drudges and jigs. SUBSTANCE: line has successively installed and interconnected by hauling units a device for disintegration and sizing with a stacker, jigging machines for main and cleaner-cell operations, concentrators for main and cleaner-cell operations. Besides, the line is furnished with a sizing screen with a stacker and at least with two centrifugal apparatuses and one more concentrator. The sizing screen and one of the centrifugal apparatuses are installed in succession between the jigging machine for the main operation and concentrator for the main operation; the sizing screen is connected to the tailings outlet of the jigging machine for the main operation, and the centrifugal apparatus concentrate outlet is connected to the concentrator for the main operation; the second centrifugal apparatus and concentrator are installed in succession at the end of the line; the centrifugal apparatus is connected to the tailings outlets of the jigging machine for the cleaner-cell operation and concentrators for the main and cleaner-cell operations, and the concentrate outlet is connected to an additional concentrator. EFFECT: enhanced extraction due to reduction of loss of fine gold. 1 dwg
