Résumé des résultats (Abstract) (Anglais)

In aluminium production Fe, Si and Mn are common sources of contamination. It is possible to remove these contaminations by the active formation and subsequent removal of inter-metallics. To make this process economical the inter-metallic formation should be optimised by the addition of extra trace elements. A systematic experimental search program will be carried out to find the economically optimal additives. The subsequent removal stage requires very accurate temperature control and the development of an advanced aluminium filtration technology such as displacement washing. These developments will be undertaken at lab-scale, and then scaled-up. The final result of the project will be a semi-continuo us in-line filtration module for the removal of Fe, Si and Mn at a cost of less than 200 USD/t. The technology will be applicable in a typical aluminium castho use, for instance between the melting and casting furnace.
