Abstract

La présente invention concerne un procédé de réduction du laitier de plomb selon lequel le laitier subit, par le haut d'une lance submergée, une injection d'un gaz contenant de l'oxygène et d'un combustible, par l'intermédiaire d'une lance verticalement suspendue dont l'extrémité inférieure est plongée dans le laitier. L'injection génère dans le laitier une zone de combustion dans laquelle le combustible est brûlé et génère des conditions turbulentes qui forment sur la partie inférieure de la lance un revêtement de laitier qui est solidifié par l'effet refroidissant du gaz injecté. L'injection est conduite dans des conditions réductrices, en utilisant une substance sulfurée en tant que réducteur, afin de réduire le plomb dans le laitier en plomb métallique et former ainsi une phase de plomb fondu, lequel peut être coulé en tant que plomb d'AEuvre.
