Pyrometallurgical and hydrometallurgical processes have been developed to recover aluminum, silica, and other components from black dross [4,5].Both processes have advantages and disadvantages [4,6,7,8].In the hydrometallurgical treatment of black dross, either acidic or alkaline solutions are employed to selectively dissolve components from black dross [9,10].
Aluminum dross is one kind of by-products of aluminum industry, aluminum content from that will share 1%-12% of the total loss in the aluminum production process. Recovery aluminum from aluminum dross can reduce the cost, protect the environment, save the energy and improve resource utilization, which has big economic and social benefits.
At ALCAN's plant located in Jonquiere, Canada, the plasma furnace is designed to recover Aluminum from dross without using molten salt. It is in operation since 1995. The plant consists of two rotary furnaces with a 2 MW Westinghouse Marc-11H plasma torch on each furnace. The furnace is charged in a batch mode and heated with plasma heated air.
Thermo-mechanical treatment of the aluminium dross to recover the entrapped metal (a ... dross. The preliminary grinding step may be followed by a physical separation of the larger malle-able particles containing a predominant metallic core, or added directly to the leaching step to pro-
During ball milling, aluminum metal and other components in the dross will be separated and reach difference particle sizes that is suitable for the recycling, through the impact, grinding and crushing of the ball mill medium, a luminum dross will be screened in different grades for the recovery.
of environmental concerns. Thus, this dross is sent back to the smelter for recovery. However, all energy associated with the initial melting of the aluminum is lost and then the smelting process must heat the dross to extract the molten metallic aluminum. 2. Copper: Dross for the copper-based metalcaster is also a source of energy loss. It

Processing of hot aluminum dross in India Processing of hot aluminum slag in India It is reported that the aluminum dross generated in aluminum industry is about 5 million tons in the world, but only half can be processed to recover aluminum from aluminum dross In the past, the aluminum dross recovery method has the following disadvantages 1 ...
The process produces aluminum dross for about 30 to 40 kg per ton product ; Aluminum dross will also be produced during the process of recycling aluminum scrap. The recovery rate of scrap aluminum recycled and reprocessed into products is generally 75% to 85%.
Aluminum dross makes up a substantial portion of a secondary aluminum smelter's total feed. However, fine dross (<10 mesh) is being discarded as industrial waste. ... followed by wet grinding …
A method for recovering reusable materials from aluminum dross is disclosed comprising crushing the dross and extracting solubles therefrom with water in a digester. The brine so obtained is processed in a crystallizer to obtain fluxing materials contained therein, and the insolubles are furnaced to separate the free aluminum metal therefrom.
aluminum dross is crucially important. Aluminum dross undergoes industrial treatments to extract valuable products, including metallic aluminum. Basically, two methods of Al dross treatment are used: (1) pyrometallurgical, which is a conventional method of treating Al dross, liberat-ing metallic aluminum in the liquid state, and (2)
98% aluminum recovery (20% higher than Rotary Salt Furnaces (RSF)) 50% lower Opex than RSF. Lower carbon footprint, ideally for large greenhouse gas emitters such as smelters.
