METHOD OF MAGNETIC SEPARATION AND DEVICE TO THIS END

摘要

FIELD: process engineering.SUBSTANCE: invention relates to ore dressing and may be used in separation of ore. Proposed method comprises feeding initial pulp in the inhomogeneous magnetic field, extracting magnetic grains from moving pulp into magnetic product and removing nonmagnetic grains and water into nonmagnetic product. Said pulp is laminated in fine and course layers under gravity and hydrodynamic forces. Note here that fine magnetic grains are extracted into magnetic product from top fine-grain pulp layer. Note also that coarse magnetic grains are extracted from bottom coarse-grain pulp layer in the weak magnetic field zone are not extracted and withdrawn into nonmagnetic field.EFFECT: higher quality of concentrate.3 cl, 2 dwg
