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. The GPIL Process is the Ore ground to the required fineness through wet grinding process mainly by Ball Mills and the slurry is dewatered by pressure filtration.Reduction of Iron Ore Pellets with a particular percentage of binders i.e. 2 of Dextrine and Upgrading naturally found iron ores is accomplished by grinding the ore into fine particles so that the iron containing materials can be liberated from unwanted gangue. This beneficiation process leaves the iron ore in a finely ground state that is.

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. The Hira Process is the Ore ground to the required fineness through wet grinding process mainly by Ball Mills and the slurry is dewatered by pressure filtration.The total metal content of iron ore concentrate is much higher than that of the iron ore. After the crushing, grinding, mineral processing, the iron ore concentrate is ready for the production of steel pellets. Good pelletizing performance of iron concentrate is the basis and premise of producing high quality pellet. Use of iron ore concentrate.

The preparation of iron ore pellets begins with the crushing and grinding of iron ore into a fine powder, and adding reducing additive coke (C) and binding agents and mixing. The mixture is added to a pelletizing machine or ball mill along with a pre determined amount of moisture to form green pellets. These green pellets are air dried and.High Pressure Grinding is applied in iron ore pellet feed preparation to generate a specific surface area increase. The technology is applied for final grinding of fine concentrates or pre-grinding (ahead of conventional milling) of particles. The process assumes inter-particle breakage and inter-particle abrasion as a major factor in generation of fines which contribute to an effective.

Iron ore pelletisation. BRPL is in operation in producing iron ore pellets from iron ore concentrates after beneficiating low grade iron ore fines. The low grade fines with Fe less than 56-57 are beneficiated at beneficiation plant through grinding, gravity magnetic separation process to produce high grade iron ore concentrates with 63-64 Fe.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.
