Iron Ore Pellets are formed from beneficiated or run of mine iron fines. The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent. If the ore is a Hematite ore, coke or anthracite coal can be added to the mix to work as an internal fuel to help ...
Iron ores. The ratio of fines to lumps at the time of mining itself has been increasing on an average of 1% every year. Another 1015% fine is generated at the time of converting it into sized ore, handling at mines, railway sidings and ports. Need for Pelletization
Nov 26, 2014· Iron Ore Pellets and Pelletization Process. Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process.
Indian iron ore mining mess – Opportunity for pelletization tech. If not, then not only the process becomes very costly but causes enormous can also be made out of iron ore beneficiation plants where ferrous fines can .
Silicate fluxes like pyroxenite and olivine shows improvement in high temperature metallurgical properties but still could not met the desired quality due its improper assimilation, and high content of alumina in iron ore. Carbonate fluxes like limestone or dolomite is more often used in pelletization for alternative iron making processes.
Iron Ore Pelletization is an agglomeration process of the disintegrated Iron Ore fines into Iron ore Pellet which is suitable for the utilization of downstream process of Iron Making.
