MASS-EXCHANGING PROCESSES REALIZATION METHOD Russian patent published in 1996 - IPC

Abstract RU 2056931 C1

FIELD: heterogeneous processes realization, for example, lixiviation, sorption, extraction, crystallization. SUBSTANCE: process is exercised by multistage contacting of phases. Phases are given motion in the form of independent rotating layers in apparatus like transport pipe. Rate of apparatus rotation is 2 - 20 rounds/minute. Angle of apparatus inclination is 4 - 10 deg.. EFFECT: decreased duration of process due to mass-exchange realization without mixing and dispergation of phases, simplification of apparatus and processing schemes, increase of crystals size, fine grinding of ore. 8 dwg, 7 tbl
