An improved method for separating a slack wax into a wax fraction and a lube oil fraction is disclosed. The method comprises passing the slack wax into a first mixing zone and subsequently into a second mixing zone. Solvent selectively miscible with the lube oil fraction is added to the zones. The temperature of the solvent added to the second mixing zone is substantially higher than the temperature of the solvent added to the first mixing zone. This process produces a wax fraction having a relatively low lube oil content.
