Abstract
A method of separating sludges which involves adding an insoluble mineral colloidal suspension into an industrial sludge to destabilize the industrial sludge and separating destabilized components of the industrial sludge. The insoluble mineral colloidal suspension can be adding into the industrial sludge or formed in situ therein by components into the industrial sludge that react together therein to form the insoluble mineral colloidal suspension.
