The major raw materials for the Remelt plant are; high purity aluminium (HP) imported from South Africa as ingot, aluminium scrap either generated from internal processes or bought from scrap dealers and companies outside disposing disused aluminium products. Alloying elements like silicon, magnesium and the grain refiner titanium-boron, which are added to improve the properties of the metal, are also imported from South Africa. The main aluminium alloys produced are 6063 alloys for architectural, engineering and irrigation purposes and 6261 alloys for the transport and engineering products. 99S alloy and 6082 alloys are also produced for selected products.

 Relting of the scrap and the ingot is done in a reverbatory furnace, which is a liquid fuel fired furnace that has output capacity of about 5000kg per charge. The reverbatory furnace consists of a steel lining shell with an inside refractory work of brick and castable refractory. The furnace can use the following fuels interchangeably: used-oil, diesel, paraffin, or coal tar. Currently used-oil is the predominant fuel. 

The cast logs undergo a heat treatment process called homogenizing to make them easier to extrude. This is carried out by heating the logs in an electric furnace at temperatures of 575 +/- 10 ^oC depending on the alloy. After homogenizing, the logs are transferred to a cooling chamber where they are cooled under controlled conditions using forced air so as to preserve the state attained during homogenizing.

 The cooled logs are then transferred to the billet saw where they are cut into shorter lengths called billets more suitable for the extrusion process. The billets are stamped with an identity number, length and respective alloy. The cut billets are then transferred to the ultimate customer, the extrusion Department.
