PROCESS COMPLEX OF TESTING PLACER DEPOSITS Russian patent published in 1998 - IPC

FIELD: mining; may be used in bulk testing of rock mass from placers, complex gold-diamond deposits. SUBSTANCE: complex consists of sampling unit (scraper winch) hydraulic giant, unit of preliminary disintegration and reducing the samples of hydraulic elevator, pressure pulp line, deslimer, unit of preliminary treatment of samples (screens), concentration units and unit of water treatment. Rock mass is supplied to receiving bin where disintegration and reduction of volume take place by settling down the material sizing 200 mm through template to accumulating chamber. Remaining part of rock mass in bin is disposed to sand-clay refuse part of the ground area. Grainy material sizing 20 mm is supplied to deslimer whose upper outlet hole is intended for overflow of suspended clay particles and connected with hollow of settling vessel. Lower outlet hole of deslimer is connected with unit of preliminary treatment of samples where material is separated into classes 20 + 2 mm and 2 mm which are supplied, respectively, to concentration units for production of gold- diamond-containing concentrates. EFFECT: higher efficiency. 3 dwg
