Aluminum dross is activated by mechanically milling to particles of about 45 μm. This leads to removal of surface layer of the aluminum particles and creation of a fresh chemically active metal surface. In contact with water the hydrolysis reaction takes place and hydrogen is released. In this process a Zero Waste concept is achieved because

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.

As a hazardous waste, secondary aluminum dross has troubled the aluminum industry for many years. A coupled life cycle assessment and life cycle costing method was used to evaluate the environmental impacts and economic cost of three emerging processes for recovering secondary aluminum dross in China. The results showed that the ball milling scenario had the smallest environmental impacts, and

The aluminum recovery from white aluminum dross by a mechanical treatment and sizing followed by remelting process was investigated. The dross was subjected to a ball mill, and the obtained particles were sized in different ranges. They were studied by advanced materials characterization techniques. It was found that the larger particles contain high metallic portions, and most non-metallic

An example of mechanical cleaning is the dry milling process. Cold aluminum-laden dross and other residues are processed by milling and screening to obtain a product containing at least 60 to 70 percent aluminum. Ball, rod or hammer mills can be used to reduce oxides and nonmetallic particles to fine powders for ease of removal during screening.

Aluminum is a critical material in the U.S. construction, packaging, and transportation industries. The aluminum industry produces approximately one million tons of waste by-products from domestic aluminum smelting annually. The most significant by-products are called salt cake and dross, and are generated in the smelting process.

Aluminum smelting dross: problems and solutions. Dross is a surface layer on a metal melt, which has a high oxide content. Slag is formed on the surface of melts as a result of interaction with air gases, primarily, with oxygen. Slag is a physical mixture of oxides and other solid compounds, as well as molten metal, which is inside them.

Dross formation in the aluminum melting and/or refining is avoided partially or totally by the method of this invention. The method is useful in unmodified open top furnaces. The elimination or reduction of dross formation is carried out throughout the body of molten aluminum by the installation of gas injection devices to extend through the refractory lining in the bottom of the furnace.

Aluminum dross, a byproduct of the aluminum melting process, is a mixture of aluminum, its oxides, the oxides of alloying elements and less frequently halogenides, carbides and nitrides. Dross has some good benefits, especially considering tension strength and depending on further conditioning steps can be very useful further on.

Your dross is from normal foundry work and cold, the way to do it is to break up any big lumps and then mill the dross in batches in a drum with steel balls in it, the resulting dust isd extracted and the droplets of ali are recovered by screening. This is the only way I know that actually works without re-refining the ali oxdes.
