Study of Scale Effect on the Iron Oxide Reduction


Article Preview

According to the analysis of iron element purification in the current process of steel production and the study on reduction experiment of ultrafine iron ore powder, this study first summarizes and puts forward the scale effect on reduction of iron oxide. And on this basis, a new concept is proposed, named precise reduction, which includes the pre-processing—dissociation of iron oxide, preparation of ultrafine powder and the post processing—non-molten magnetic separation. Taking high phosphorus hematite, steelmaking slag and metallurgical dust as the study objects, and the better achievement shows that the low grade iron-bearing material, after precise reduction, can be transformed to the valuable resource without residue, and the process is environment friendly with low energy and material consumption, so that the zero discharge can be achieved. Not only does the steel plant be changed to be environment friendly, but also the resource is got.
