Abstract
In a method for processing dusts or dust mixtures containing alkalis and heavy metals, such as, e.g., steelworks dusts, fine ores or blast furnace dusts, the dusts are charged onto or into, in particular top-blown on or blown into, a bath of molten metals and liquid oxidic slags. Volatile heavy metal compounds such as, e.g., Zn and/or Pb oxides are separated from the gaseous phase and alkalis are introduced into the slags.
