A method is disclosed for recovering valuable metals contained in various metallurgic waste precipitates and dusts, and also for forming the rest of the waste precipitate or dust into a slightly soluble product suitable for further processing. The recovery of valuable metals and the forming of slightly soluble products is carried out in a suspension smelting furnace, in which case the smelting of the precipitates and dusts is conducted under mainly reducing conditions.
Méthode permettant, d'une part, de récupérer des métaux utiles contenus dans divers précipités et poussières de déchets métallurgiques, et, d'autre part, de faire du reste de ces précipités et poussières un produit légèrement soluble susceptible d'un traitement postérieur. La récupération des métaux utiles et la formation de produits légèrement solubles sont exécutées dans un four de fusion à suspension, et la fusion des précipités et des poussières se fait alors dans des conditions principalement réductrices.
