Abstract:
A process for separating from a fluid-particle mixture particles having a given degree of magnetic susceptibility relative to the magnetic susceptibility of remaining particles, the process comprising:supplying the mixture to an inlet opening of a chamber containing at least one ferromagnetic matrix separation element, said at least one matrix separation element having a longitudinal axis and comprising stainless steel filament wound on a porous mandrel;directing a high intensity magnetic field through said chamber in a direction parallel to the longitudinal axis of said at least one matrix separation element, whereby the direction of the magnetic field is normal, parallel, or oblique to a thickness dimension of said at least one matrix separation element;causing said mixture to flow in parallel flow paths through said at least one matrix separation element in the direction of the thickness dimension thereof and thereafter out of said chamber through an outlet opening thereof, whereby the particles having a given degree of magnetic susceptibility are retained on said at least one matrix separation element.
