ABSTRACT:
A method for the production of an enriched iron product, specifically direct reduced iron and iron oxide suitable for use as the feedstock for steel mills, from industrial waste streams containing iron, by combining an iron oxide rich material such as mill scale and/or used batteries with the waste streams, treating the combined waste stream with an ammonium chloride leaching solution, separating the undissolved precipitates comprising iron compounds from the leachant solution, and further treating the undissolved precipitants by elevated temperature roasting, resulting in the iron feedstocks.
