PROCESS FOR RECOVERING METALLIC COMPONENT FROM METALLURGICALSLAG PRECIPITATE OR FINE SLAG POWDER BY SUSPENSION MELTING

摘要

The present invention relates to a method for recovering valuable metals contained in various metallurgic waste precipitates and dusts, and also to a method for forming of the rest of the waste precipitate or dust a slightly soluble product suited 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 mainly reducing.
