A Guide to Reducing & Treating Aluminum Dross

The dross that forms on aluminum melt is normally considered to be an undesirable material. While it is the source of much grief in operations that melt aluminum or aluminum alloys, the solid form of dross is far from being undesirable and in truth is a valuable co-product that can have a major effect upon the profitability of the producer’s operation. It often contains large quantities of entrapped useful aluminum alloy. Value can be lost from the process stream during the normal dross removal and cleaning process unless great care is exercised at the generating source, or is recovered in subsequent recycling efforts.

Guidelines for Reducing & Treating Aluminum Dross focuses on dross formation, the influence of furnace type and operational procedures on dross, fluxing, the economic implication of dross, techniques for the recovery of dross, and ways to reduce dross formation.
