Benefication, sintering and processing of raw materials for the iron and steel industry

Beneficiation of iron ores relates not only to enrichment of the metal content but also to improvements in physical characteristics of the ore charged into the blast-furnace. The latter is achieved by crushing, sizing and agglo-meration of resultant fines etc. It is universally reco-ginzed that preparation of sized iron-ore burden and use of fluxed sinter in iron production can achieve (i) redu-ction in coke rate by reducing the metallurgical load on the blast-furnace by better utilization of available heat and (ii) increased productivity.
