Abstract

Procédé et dispositif pour l'affinage de métaux fondus. Le métal liquéfié s'écoule en continu, sur une faible hauteur, au long des zones de réaction 11 à 14, dans chacune desquelles une impureté différente est éliminée chimiquement par addition de réactifs 27 à 30. Les produits de réaction 35 formés par les impuretés sont recueillis au niveau de chicanes 18 à 20 placées entre deux zones consécutives. Amélioration du rendement par rapport aux procédés traditionnels.Method and device for refining molten metals. The liquefied metal flows continuously, over a small height, along the reaction zones 11 to 14, in each of which a different impurity is chemically removed by the addition of reactants 27 to 30. The reaction products formed by the impurities are collected at baffles 18 to 20 placed between two consecutive zones. Improved performance compared to traditional processes.
