Process and means for the removal of iron rust from cast iron borings or chips to prepare the same for melting. The process involves the heating and agitation of such borings or chips, converting the rust of the same to magnetite and chemically uncombined water, eliminating the water from the chips or borings, screening the particles to remove the converted material, charging the balance of the substantially oxide free borings into a melting furnace, wherein the rate of the charge and the melting temperatures can be maintained substantially constant during the melting process to provide a uniform slag-free operation.
