Abstract
A method for producing direct reduced iron or/and pig iron from an industrial waste materials stream such as EAF and blast furnace dust generally comprising the steps of separating the materials contained in the waste materials stream by magnetic separation or flotation, briquetting the iron-containing materials separated during the separation process with carbon, and providing the briquettes to a reduction furnace or/and to a small scale blast furnace or cupola furnace to produce direct reduced iron or/and pig iron, respectively. The exhaust streams from the process are further treated to recover chemical values and to allow the recycle of the exhaust streams to the main process.
