Aluminum castings have played an integral role in the growth of the aluminum industry since its inception in the late 19th century. The first commercial aluminum products were castings, such as cooking utensils and decorative parts, which exploited the novelty and utility of the new metal.
aluminium dross and subsequent residues are. Aluminium recycling The dross produced by the aluminium industry, although a waste, contains aluminium and other valuable elements (aluminium oxides), which could be recovered and reused. Conventional methods recycle less than half of all white dross and all black dross is sent to landfill.

A cradle -to-gate system of primary (or electrolytic ) aluminium production is shown in Annex B. It includes bauxite mining, alumina production, carbon anode production, aluminium electrolysis, ingot casting, raw materials transport, electricity generation, and aluminium dross processing.
An aluminum dross waste from plasma processing for Al metal reclamation was tested as a replacement raw material in refractories. The main phases of the starting Al dross waste material were MgAl 2 O 4 and AlN. The waste was tested to replace calcined alumina in castables and refractory clay in a molded refractory at levels below 6.5%.
Depending on its source, aluminium scrap may contain a range of impurities. These can be removed via pre-treatment processes or in the melting furnaces. Scrap such as used beverage cans (UBCs) and turnings sometimes require the removal of coatings or oils prior to melting, to improve metal recovery and to reduce potential emissions.
Aluminium dross is an industrial waste from aluminium refining industry and classified as toxic substances. However, the disposal of dross as a waste is a burden to aluminium manufacturer industries due to its negative effects to the ecosystem, surface, and ground water. Therefore the purpose of this study is to evaluate the influence of sodium hydroxide (NaOH) on the surface area and pore ...
