Dross Treatment Weston Aluminium specialises in providing recycling solutions to the primary and secondary aluminium sector. Weston Aluminium does not use salt or any fluxes when processing aluminium dross and scrap. This has resulted in a 50% reduction in the generation of waste to landfill and a significant reduction in energy consumption.
Basically, two methods of Al dross treatment are used: (1) pyrometallurgical, which is a conventional method of treating Al dross, liberating metallic aluminum in the liquid state, and (2) hydrometallurgical, which involves an extraction of metallic aluminum from the Al dross by converting it into aluminum salts and compounds.
The worldwide aluminium industry produces nearly five million tonnes of furnace waste each year. Known as dross, the residual waste material is produced from any process in which aluminium is melted, and is left behind after conventional recycling has been carried out. Traditionally, black (which has a much higher salt content) and white dross ...
Another 10,000 tonnes or so of aluminium dross is also expected to be trucked back to Tiwai from other spots in Southland, where it has been scattered since the 1990s. Ouvea premix - or dross - is stored in loose bags around Southland. Photo: Sort out the Dross facebook page Robertson went ahead and approved the Mataura indemnity.

The recovery rate can be 91% and the burning rate of aluminum can be reduced to 4%. Our aluminum machine belongs to this type of dross machine and it has a high recovery rate, no need any fuel and a short working time, processing 100-500 kgs aluminium dross in 10-12 minutes. 2. The pressing recovery process method
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%. Recycling one ton aluminum dross will produce more than 100 kg extra aluminum dross.
Dross is formed on the surface of molten Aluminum or its alloys by oxidation. Dross is a valuable by product of any Aluminium Smelter or Aluminium Foundry. Dross is recycled to recover the valuable Aluminium Metal world wide. Typical dross generation from a primary operation can be from 0.8% to 1.3% of Aluminium output.

Dross is a by-product of all aluminum melting processes. Depending on scrap type, alloy treatment and melting equipment, the amount, metal content and properties of dross vary in a wide range. Dross is a mixture of aluminum, …
Aluminum smelting dross: problems and solutions admin Dross is a surface layer on a metal melt, which has a high oxide content. Slag is formed on the surface of melts as a result of interaction with air gases, primarily, with oxygen. Slag is a physical mixture of oxides and other solid compounds, as well as molten metal, which is inside them.
As discussed earlier, aluminium dross is a byproduct of the aluminium smelting process. It can be mechanically recycled to separate the residual aluminium metal from the aluminium oxide. Infact, hot dross processing is a system whereby the majority of metal is recovered without chemically reducing the aluminium oxides.
