MAGNETIC HYDRAULIC SEPARATOR Russian patent published in 1999 - IPC

FIELD: washing magnetic concentration of natural deposits, preferably fine-grained ore. SUBSTANCE: main magnetic system is designed as permanent magnets which opposite poles provide slots in bottom of feeding tank. Slots in their beginnings are parallel to linear rotation velocity vector of suspension in tank. In addition each magnetic plate of additional system is glued with magnets on its both sides. External poles of said magnets have same sign on its surface but are opposite on both sides of plate. EFFECT: increased output of concentrated ore, decreased content of iron (ore particles) in waste. 2 cl, 1 dwg
