OBTAINING PRIMARY ALUMINIUM FROM RECYCLED ALUMINIUM
BEFESA GENERATES 60,000 TONNES OF PAVAL PER YEAR, a byproduct of the recovery of salt slag with more than 60% weight of aluminium oxide, which also contains aluminium hydroxide and a series of salts and oxides that prevent its recovery by electrolysis to obtain primary aluminium. The mixture of metal oxides that makes up Paval offers the possibility of obtaining complex aluminium alloys with these metal elements from their oxides, which would reduce the need to obtain these alloying elements (copper, titanium, manganese) through other electrolytic processes and further processing required to be incorporated into the final alloy, thus drastically reducing the energy required and metal wastage that occurs during alloying.
BEFESA, a leading company in technological solutions for aluminium recycling, leads ALUREC with the collaboration of ECOINDAL, aluminium producing and processing company, and TECNALIA Technological Centre.
