ABSTRACT:
A process which is especially useful for effecting magnetic separation of magnetically attractable impurities from an aqueous clay slurry or suspension includes passing the suspension through a porous, ferromagnetic matrix while applying a magnetic field to the matrix, on which impurities are collected, and thereafter regenerating the matrix by flushing collected impurities therefrom with a flush liquid, e.g., water. The improvement comprises, after discontinuing the passage of the suspension through the matrix, but before passing flush liquid therethrough, admitting a pressurized gas, e.g., compressed air, into the separator to displace suspension retained therein, and recovering the displaced suspension. In addition, flush liquid retained in the matrix after the flushing step may be displaced therefrom by the compressed air. By displacing the retained suspension from the matrix with, e.g., compressed air, instead of a flush liquid, e.g., water, the retained suspension is not diluted by flush water and is recovered instead of sewered as in the prior art processes.
