Upgrade of aluminium scrap
The use of primary aluminum is more expensive than aluminum scrap for aluminum smelters but scrap aluminum can only be used for a maximum of 10% due to the high content of Zinc, Copper, Ferrous, and Magnesium in it.
Separation technologies for aluminum scrap
Scrap aluminum is processed by various SGM technology separators, such as X-ray sorters, eddy current separators and magnetic ferrous separators and segregates the parts with a high content of Zn, Cu, Fe and Mg. The result is a main stream of scrap aluminum with Zn, Cu, Mg and Fe reduced by a multiple of times. With aluminum profile scrap, Zn can pass from the typical 0,16-0,25% down to 0,03-0,05%. With taint tabor, Zinc can pass from the typical 0,5% down to 0,10-0,15% and in the case of tense, can pass from the typical 5-6% down to 1-2%.
The result of the SGM technology and experience allows for increasing the percentage of the aluminum scrap in the infeed material to the smelter to over 80% leading to important savings on the aluminum sourcing cost.
With multiple references at aluminum smelters all over the world (Italy, Spain, Germany, the UK, USA, Korea, China, India, …) SGM’s customers can benefit from its extensive experience.
SGM supply can be customized to meet the customer’s needs and preferences, including turn-key solutions or sole supplier of the main separators.
