成果简介	NOVELTY - Recovery of metallic iron from iron bearing waste resources as input material including a combination of hydrometallurgical and electrometallurgical process of recovery of iron values from waste resources comprises leaching iron values from provided iron bearing waste resources as input material with hot sulfuric acid at 200-210℃ such as to recover iron values from the iron bearing waste resources as ferric sulfate solution; adding metallic iron including iron (Fe) scrap or DRI fines to the thus separated iron bearing ferric sulfate in solution to convert the ferric sulfate to ferrous sulfate solution suitable for electrometallurgical processing; and subjecting the ferrous sulfate solution to electrolysis to recover the metallic iron values from the iron bearing waste resources. USE - Method for recovery of metallic iron from iron bearing waste resources as input material including a combination of hydrometallurgical and electrometallurgical process of recovery of iron values from waste resources. ADVANTAGE - The method develops extraction process for the recovery of iron values from the slime or lean ore, improves sustainability enabling viable extraction of high purity iron from lean iron sources with the high purity iron attained thus reduces/eliminates the need for coke based reduction process with the anode evolving oxygen 20000 L/ton during electrolysis additionally provides a greener environment.
