iron ore grade wise proportionate use in direct reduced plant

Direct reduction DR is defined as any process in which metallic iron is produced by the reduction of iron ore at temperatures below the iron melting point The product of a DR process is called direct reduced iron DRI The major consumers of DRI are the smaller steel mills which use DRI to dilute the residual elements present in the steel scrap
