CONTINUOUS-FLOW PROCESS LINE FOR PROCESSING METAL-CONTAINING MIXTURE OF PLACERS Russian patent published in 1997 - IPC

FIELD: mineral dressing. SUBSTANCE: invention relates to processing rare and precious metals. Continuous-flow line contains apparatus for disintegrating starting material made in the form of hydraulic buddle with hydraulic monitor, conical hydraulic cribble, arrangement to catch concentrate particles made in the form of gravity sludge line - tilted pipeline with discharge branch pipe installed in its lower part at predetermined distance from the inlet end, magnetic separator for isolation of strongly magnetic fractions in liquid medium, dehydrating sizing screen, drying apparatus, magnetic separator for dry isolation of slightly magnetic fractions, and arrangement for isolation of nonmagnetic fractions in the form of ferrohydrostatic or electrodynamic separator. Continuous-flow line may also have a unit for recleaning of products of drainage from dehydrating sizing screen containing sump, additional pump to pump over sludge, concentrator in the form of, for example, a set of hydrocyclones, dehydrating vibration screen, and additionally built- in magnetic separator for dry isolation of slightly magnetic fractions connected with vibration screen directly or through built- in additional drying apparatus, and also arrangement for isolation of nonmagnetic fractions in the form of ferrohydrostatic or electrodynamic separator. EFFECT: improved process flowsheet. 13 cl, 5 dwg
