Secondary aluminum dross (SAD) is a typical and unavoidable waste in the aluminum industry, with an annual global production of more than 1 million tons [].Depending on the scrap source, SAD usually contains 20–60 wt% α-alumina, 5–10 wt% aluminum, 5–50 wt% salt flux (NaCl, KCl and fluoride salts, etc.), and other minor …
The aluminum dross contained aluminum nitride and would cause odor while being disposed in landfill, making the aluminum dross disposal a tough issue. 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 …
Abstract. Aluminum dross (AD) from aluminum alloy production is harmful for the environment, while it also contains valuable metal and oxides. Therefore, its …
Aluminum recycling offers advantages in terms of environmental and economic benefits. The presence of deleterious impurities in recycled Al alloys is increasing and this is the main …
The amount of waste, associated waste disposal costs, and environmental contamination may be minimized by identifying effective recycling approaches. These promising approaches will also lead to the protection of natural resources and economic gains. One example of waste disposal maybe by using it as a filling material or as a …

By Alton Tabereaux, Contributing Editor. Spent potlining (SPL) disposal is one of the largest environmental waste management challenges confronting worldwide primary aluminum smelters due to its toxicity. The International Aluminium Institute (IAI) asserts that 1.6 million tons of SPL were generated from primary aluminum production in …
In this study, the hydrolysis behavior and kinetics of AlN in aluminum dross (AD) were investigated in order to better identify the steps controlling the AlN hydrolysis reaction and the factors influencing the hydrolysis rate to enhance the removal efficiency of AlN. The hydrolysis behavior of AlN, including AlN content, phase composition, chemical …
In terms of production volume, aluminium is the leading metal in non-ferrous metallurgy. In particular, the recycling of aluminium-containing residues has strongly increased in recent years and will continue to gain importance in the future. Due to the high affinity of aluminium to oxygen, the oxidation of the molten bath is unavoidable, which …
