Minimizing Melt Loss in Aluminum Recycling

The handling of dross is an unfortunate but necessary activity of melting aluminum in a reverberatory (reverb) furnace. Recyclers have been working on ways to minimize melt loss and improve metal recovery for over 100 years. Even so, as much as 3% of the scrap can still end up as dross. Big savings can accrue if this metal can be recovered, but this is only possible if dross is properly Get price

Fluxes for melting aluminum [SubsTech]

Jul 28, 2012Drossing fluxes promote separation of molten aluminum entrapped in the dross (sometimes up to 80%). Besides chlorides and fluorides drossing fluxes contain oxidizing component (KNO 3) reacting exothermically with aluminum when heated.Heat generated by drossing flux improves wettability and fluidity of the entrapped aluminum, drops of which coalescence and flow down to the Get price

DEVELOPMENT OF ALUMINUM DROSS

Aluminum dross is a by-product of Aluminum production. At present, dross is processed in rotary kilns to recover the Al, and the resultant salt cake is sent to landfills; although it is sealed to prevent from leaching, the potential for leaching exists andcould harm the environment as the salt cake contains fluorides and other salts.
