A method for the recovery of iron products, specifically direct reduced iron and iron oxide suitable for use as the feedstock for steel mills, from industrial waste streams containing iron, by treating the waste streams 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. |
