from and independent of ore mines. In such cases, the receiving method involves the transportation of the ore in a dedicated ship, unloading the ore at a quay and stockpiling it in a yard. Iron ore must be shipped in bulk for maximum economy. 1.2 Pretreatment process In this process, the iron ore is ground into fines
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.
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 10-15% fine is generated at the time of converting it into sized ore, handling at mines, railway sidings and ports. Need for Pelletization

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 ...
Use of Boron Compounds as Binders in Iron Ore Pelletization Osman Sivrikaya* and Ali Ihsan Arol Middle East Technical University, Department of Mining Engineering, 06531 Çankaya, Ankara, Turkey Abstract: Low grade iron ores with impurity gangue minerals containing silica and alumina must be upgraded to an acceptable level of iron content.
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.
The mineralogical composition of the dolomite powder plays a vital role here. Our dolomite powder is highly pure and minimum 95% of it comprises of CaCO3 and MgCO3. Silica content is less that 2%. Alumina, iron oxide and other insoluble impurities are in all not more than 1.5%. Moisture content too, is .
