Dross is formed when molten aluminium reacts with atmospheric oxygen, creating an oxide film on the metal's surface. This oxide product is called aluminium dross, a combination of metallic aluminium entrapped in alumina and salt transitions used in smelter plants. The challenge lies in efficiently separating the metal from the oxide.
Air toxics, also known as hazardous air pollutants, are those pollutants known to cause or suspected of causing cancer or other serious health effects. Secondary aluminum plants recover aluminum from scrap such as beverage cans, foundry returns, other aluminum scrap, and dross.
When skimmed from a furnace, dross can contain up to 80% aluminum [] which, if neglected, can diminish quickly through oxidation and be forever lost from the metal stream.To put this in context, the approach shown in Fig. 1 can cost a relatively small aluminum producer many hundreds of thousands of dollars per year. Additionally, poor …
Therefore, the aluminum dross was mostly stored in the original plants. The objective of this study is to develop an economically-feasible and environmentally-friendly technology to recover aluminum dross. In this study, the original aluminum dross was collected from the secondary smelting aluminum dross factories with 33.6% Al. …

The type of dross is also determined by ascertaining its parent composition: whether it is derived from alloys or pure aluminium (Xiao et al., 2005, Yoshimura et al., 2008). Primary and secondary smelters generate 1.5–2.5 % and 8–15 % of white and black dross per ton of
The Al extrac-tion rate from aluminum dross (AD) reached 86.21%, the denitrification rate reached 99.54%, the concentration of soluble fluoride ion was reduced to 0.111 g·L−1, and the fluoride fixation rate was 75.04 wt%. CaF2 is the main component of the leaching residue, which can be added as an insulation material for electrolysis.

This mixture, called aluminum dross, essentially consists of aluminum oxide, metallic aluminum, magnesium spinel (MgAlO 4), periclase (MgO), quartz (SiO 2) and salts with small traces of aluminum carbides and nitrides.4 The recycling of Al dross, which is a by-product obtained during production of aluminum and its alloys, is …
Recycling plays an important role in today's world due to its considerable contributions to mitigating energy concerns and environmental challenges. One of them is dross recycling from aluminum (Al) cast houses. Unlike other recyclable materials, dross has an abundance of components, including rare earth elements, heavy metals, ferrous, …
Dross is cooled. 90% metallic aluminium. 10% Al is lost due to thermiting/oxidation as the dross cools. Dross is loaded & transported off-site. Toller processes dross with RSF. 75% metallic aluminium. RSF recovers 85% of Al contained within dross. Aluminium ingots are shipped back to the smelter. 75% metallic aluminium.
The preparation of the hydrotalcite-like compounds (double hydroxides consisting of magnesium and aluminum) from aluminum dross and magnesium chloride solution, both as the byproducts of aluminum recovery plant in Japan and Spain have been informed by Murayama et al. (2012) and Gil et al. (2018), respectively.
Novelis Inc. plans to invest $2.5 billion to build a new low-carbon aluminum rolling and recycling plant in Bay Minette, Alabama — making it the first integrated rolling facility to be built in the U.S. in 40 years.
