Abstract

L'invention concerne un raffinage au feu intensif en continu du cuivre comprenant les étapes consistant: à tarauder en continu un cuivre liquide (4) dans un premier réacteur d'oxydation; l'oxydation de cuivre liquide avec des gaz de combustion renfermant de l'oxygène ou avec de l'air; à former simultanément des impuretés de recueil de crasses; à tarauder en continu le cuivre oxydé et à raffiner les crasses provenant du premier réacteur (8); à tarauder en continu le cuivre oxydé dans un second réacteur de réduction; à réduire le cuivre au moyen de carbone et à réduire des gaz formés par la combustion partielle de combustible et du carbone et à tarauder en continu le cuivre réduit (14).
