Abstract
A mixture comprising non-magnetic solids is separated according to the density difference of its components by contact with a separating medium comprised of a fluidized bed of magnetizable particles which is stabilized by a magnetic means. The separating medium circulates in a closed loop within a contacting vessel or zone such that at least two portions of said separating medium flow in essentially opposite directions transverse to the flow of the fluidizing fluid exiting the medium. This invention is particularly effective for separating mixtures of coal or for separating coal from other solids.
