A method and apparatus for separating ferrous metal particles from
non-ferrous metal particles suspended in a liquid, such as a coolant from
a machining operation, in which mixed particle containing liquid is
discharged across a horizontal, non-magnetic separating surface; the
magnetic ferrous metal particles are captured by a magnetic force exerted
by an array of parallel magnets disposed underneath the separating
surface, the non-magnetic non-ferrous metal particles are washed by the
liquid into a collecting flume from where they can be passed to a
filtering station for removal from the liquid, and the captured ferrous
metal particles are scraped from the separating surface and conveyed to a
ferrous metal discharge by a scraper conveyor which moves transversely to
the discharge direction of the liquid.
