Presentation Title The Implementation of a Comprehensive Dross Management Program at Constellium Ravenswood

Abstract Scope Dross is an unfortunate by–product of the aluminum industry. While minimizing dross generation is important, so too is the handling and treatment of the dross once it has been removed from the furnace. Preventing the oxidation of trapped metal units is only part of the solution to maximizing the true value of dross. Specialty alloy producers such as those in the aerospace industry have particular interest in maintaining metal chemistries and values. This paper details the work conducted over a 12-month period at the Constellium Ravenswood facility on the implementation of a comprehensive dross management program. Working with ALTEK to improve both dross recoveries and reduce environmental emissions, the facility has installed the latest generation dross press technology. Metal recoveries have significantly increased (both in-house and secondary) and additional savings have been realized working with the secondary processor enabling the return of on-spec alloyed material instead of traditional RSI.
