ABSTRACT OF THE DISCLOSURE An improved method for separating a slack wax (12) into a wax fraction (52) and a lube oil fraction is disclosed. The method comprises passing the slack wax (12) into a first mixing zone (20) and subsequently into a second mixing zone (30). Solvent selectively miscible with the lube oil fraction is added to the zones (20,30) The temperature of the solvent added to the second mixing zone (30) through manifold (36) is substantially higher than the temperature of the solvent added to the first mixing zone (20) through manifold (26). This process produces a wax fraction (54) having a relatively low lube oil content.
