Aluminium Dross Cooling
Aluminum dross can form on the surface of aluminum and the weight may vary from
1% to 6% or more of total aluminum production. Dross may contain between 18 to
80% of valuable aluminum.
BOC can help you develop your aluminum recovery process and increase your
aluminum recovery rate by applying argon to your dross cooling process. Aluminum
dross cooling is a process where the dross is skimmed and cooled in an inert gas
atmosphere. It is important to work quickly and efficiently to prevent the
aluminum from oxidising, which can happen if the dross is not cooled down fast
enough and remains exposed to air.
Benefits of argon for dross cooling:
- Displaces oxygen quickly
- Increases aluminum recovery rates
- Prevents oxidation of the residual metal
