Casthouse dross


 

The amount of casthouse dross produced depends on the quantity of bath contained in the metal, the amount of aluminum fluoride (AIF3) added to the latter, operations in the melting oven and the quantity of value-added products being produced. An Alcoa technical group made up of experts from each plant in the region, as well as professionals from the Smelting Centre of Excellence, share best internal practices on dross reduction and recycling.
