Aluminium dross processing
What is aluminium dross?
Aluminum dross is a waste product produced when refining aluminum. It consists of metal, salt oxides, and other nonmetallic substances. Dross is
classified as either black or white dross. Black (or dry) dross has lower metal content and higher amounts of oxides and salts. It tends to be
granular, like sand. White (or wet) dross has an extremely high metal content and a smaller amount of oxides and salts. It tends to form into large
clumps or blocks.
What is aluminum dross? and the usage of it? I am not familiar with this, but I want to know about it.
Dross is a mass of solid impurities floating on a molten metal. It appears usually on the melting of low-melting-point metals or alloys such as tin,
lead, zinc, or aluminum, or by oxidation of the metal(s). It can also consist of impurities such as paint leftovers. It can easily be skimmed off the
surface before pouring the metal into a mold or casting flask.
How to recover aluminum from the dross?
You can use an aluminum slag processor, we purchased the machine from Brightstar Aluminum Machinery, and the recycling rate is very good compared to our old machine, hope this can help you.
After the first step of treatment, a large amount of aluminum slag is melted. According to the production needs, select matching filter plates-ceramic foam filters, and degassing equipment to turn it into a high-purity aluminum liquid that can be produced and molded.
What is aluminum dross?
Aluminum dross is a mass of solid impurities floating on a molten metal. As aluminium metal melting point is 660℃, which is low-melting-point, so
it will be formed on the surface in aluminum melting or alloys by oxidation of the aluminum.
How do you melt aluminum dross?
You can use the dross processing machine to recover aluminum from aluminum dross (refining flux), or you can melt aluminum dross with our aluminum dross melting
furnace. Our suggestion is you had better process aluminum dross the melting
