Abstract: The progress in preparation of iron oxide by using three-wastes, which includes settled dust, waste liquid and waste residue in China is summarized.The harmfulness and properties of three-wastes are discussed. The technical parameters, process and preparation principles of preparing iron oxide by using three-wastes are presented. The properties of iron oxide prepared from three-wastes are determined. Finally, the research directions of preparing iron oxide by using three- wastes and its application prospects are presented.
