Abstract

L'invention concerne un procédé et un appareil permettant de contaminer des compositions métalliques fondues. L'invention concerne initialement une composition métallique fondue (contenant d'ordinaire du plomb élémentaire ou un alliage de plomb) qui comporte également divers contaminants inorganiques. Ladite composition est mise en contact avec un élément de décontamination spécialisé qui favorise activement la diffusion des contaminants dans cette composition, le résultat étant que les contaminants sont évacués de la composition métallique fondue. Les contaminants particulièrement intéressants dans des compositions métalliques fondues à base de plomb sont notamment l'arsenic, l'étain, l'antimoine, le tellure, et des combinaisons de ceux-ci. Un agent réducteur est combiné de façon optimale avec la composition métallique fondue afin d'empêcher la formation d'oxydes sur l'élément de décontamination, ce dernier contenant, de préférence, du fer sous la forme d'un alliage de fer (par exemple l'acier). Des composants additionnels préférés ajoutés dans le système de décontamination comportent notamment un piège à fer pour évacuer de la composition métallique fondue les contaminants renfermant du fer, ce qui permet de décontaminer rapidement et efficacement ladite composition.
