Description Solids are separated from a tar sands extract by gravity settling or centrifugation in the presence of a liquid promoter which promotes and enhances the separation of the solid material. The liquid promoter has a characterization factor of at least 9.75, a 5 volume percent distillation temperature of at least 250° F and a 95 volume percent distillation temperature of at least 350° F and no greater than 750° F. As a result, liquid product is obtained without the necessity of preliminary coking of the entire extract.
