摘要: In a dense medium separation process a product of a separation step containing separated material and magnetic dense medium particles is passed through a sieve bend and the undersize only is treated for the magnetic recovery of the dense medium particles.

摘要: A method for recovering magnetic dense medium particles from a suspension containing these particles and other less dense particles includes the steps of subjecting the suspension to at least a single stage high relative density separation to form a first fraction containing substantially only dense medium particles and a second fraction containing the bulk of the other particles and some dense medium particles, and subjecting the second fraction to a magnetic separation for recovery of the remaining dense medium particles. Each stage of the high relative density separation is effected in a cyclone. The suspension may be the overflow or the underflow from a dense medium process for the beneficiation of coal fines.
