METHOD OF REDUCING THE SLUDGE CONTENT OF A TAILINGS POND Abstract of the Disclosure A hot water process for processing bituminous tar sands which includes the steps of: A) forming a pulp of the bituminous tar sands and water in a conditioning drum; B) passing the pulp across screen means and discarding oversize rejected thereby; C) diluting the screened pulp; D) settling the diluted pulp in a separation zone to form an upper primary bitumen froth zone, a middlings layer comprising water and mineral, and a sand tailings layer; and E) separately withdrawing the primary bitumen froth layer and the sand tailings layer; the improvement which comprises introducing a clay-containing slurry into the conditioning drum such that the pores of clay lumps contained therein become filled to render the lumps resistant to dispersal whereby they are rejected by the screen means and discarded as oversize.
