<p>An improved method and apparatus for recovering metal values from Electric Arc Furnace (EAF) dust, particularly zinc and iron values, by mixing EAF dust and carbonaceous fines to form a particulate mixture; heating the mixture at a sufficient temperature and for a sufficient time to reduce and release volatile metals and alkali metals in a flue gas; collecting the released metals, and removing the metal values from the process as product. The apparatus may be made portable by truck or rail mounting.</p> |
