The traditional method to recover the metallic aluminium from primary dross is not an efficient and economical process because only part of the metal is recovered while consuming energy and producing pollutants (fumes, dust and salty dross)., ALURES and ALUMIX have studied and experimented a new process to recycle all the components of the dross in the …
In this study, a recycling process for stabilized secondary aluminum dross is proposed. Calcium oxide-containing materials, such as de-sulfur slag produced from steel manufacturing process, are used as stabilizing agents for secondary aluminum dross. The de-sulfur slag was first hydrolyzed. Due to the high content of calcium oxide (about 45%), hydration of de-sulfur slag …

This paper explores the preparation of hierarchical Mg-Al layered double hydroxide (LDH) from secondary aluminum dross waste for the first time. The aluminum content of the waste was initially extracted in the form of a sodium aluminate solution using a multistep wet chemical process. CO 3-intercalated Mg-Al LDH was then prepared at pH values of 9 and 11 …

Nakajima et al. (2007) performed a material flow analysis on aluminum dross in order to achieve the goals of aluminum dross recycling and environmental assessment of new developed technologies. Their analytical results showed that in 2003, about 234,000 tons of aluminum was recovered and about 215,000 tons of residual products were produced.
Most efficient aluminum smelters ship dross for recycling containing aluminum 40-50 %. Those enterprises, which do not produce dross fluxing in the furnace, can ship dross containing aluminum 75 and even 85 %. How to reduce the amount of dross

This report mainly studies aluminium dross recycling market. Aluminium dross, a by-product of the aluminium smelting process, can be mechanically recycled to separate the residual aluminium metal from the aluminium oxide. The purpose of recycling: 1.To reduce metal content in waste; 2. To reduce energy usage in aluminium production; 3. To reduce …
Disclosed is the recycling of aluminum dross. Aluminum dross is crushed into particles which are size-classified on the basis of 1 mm. The aluminum dross particles equal to or smaller than 1 mm in size are leached with an aqueous sodium hydroxide solution to give a leachate which contains sodium aluminate as a result of the reaction the aluminum metal of …
