What is Aluminium Salt Slag?
Aluminium Slag Slag (also known as Aluminium Salt Cake) is a byproduct from the secondary aluminium industry.
When scrap aluminium is placed in the furnace to be remelted, salt and potassium chloride are also introduced to act as a flux and increase the efficiencies of the process. Once the molten aluminium has been recovered, the remaining waste product must be removed and treated. This byproduct is known as Aluminium Salt Slag.
Traditionally the Aluminium Salt Slag was placed in a landfill, though the practice is no longer permitted in Australia. The EPA has designated Aluminium Salt Slag a hazardous material, and hence it may no longer be disposed of in this manner.
Alreco’s operations in Victoria treat all of the Aluminium Salt Slag produced in Australia.
