Sintering ofiron Ore Fines, and Raw Materials for Bhilai ...

2012-7-20  Numerous methods have been suggested to solve -the problem of agglomeration of ore fines, of which sintering, briquetting and nodulising or pelletising, have been tried on a large scale. Sintering, which was first developed and applied to non-ferrous ores, has proved often to be the most efficient and economical of these processes. Although the use of sinter in blast furnace burden has secondary ad-vantages, such as higher iron production, smoother furnace operation and decreased fuel consumption, the primary object of sintering in most cases is the utilisation of blast-furnace flue dust and ore fines
