1.5 Stages of Pelletizing Pelletisation of iron ore involves the following four stages: 1. Raw Material Preparation: This step involves: Grinding of iron ore to required uniform size Concentration of iron ore and separation of unwanted gangue material Addition of binders, additives, etc. for preparation of agglomeration mixture 2.


Iron ore pellets are produced from the iron ore concentrate by pelletizing and sintering and are used as the feedstock for the blast furnace process. Metinvest offers a range of iron ore pellets for the blast furnace process, such as non-fluxed pellets produced by Central GOK with a basicity of 0.1. and 65.5% iron content, non-fluxed pellets ...


Iron Ore. and Pellets. Vale is the world's biggest producer of iron ore and pellets, raw materials essential to the manufacture of steel. Iron ore is found in nature in the form of rocks, mixed with other elements. By means of various industrial processes incorporating cutting-edge technology, iron ore is processed and then sold to steel ...

Keywords: bentonite, pelletizing, iron ore concentrate, binder, sodium bicarbonate Introduction Major raw material in iron and steel industry is iron ore which can be classified as high grade and low grade in terms of its Fe content.


modern, flexible and energy efficient grinding solution for fine and ultra fine grinding being tested in an industrial scale level. The test was performed at an iron ore pellet producing plant in Sweden (for confidentiality reasons, it will be referred to only as


The iron ore pelletizing process consists of three main steps: 1. Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives anthracite, dolomite and binders are prepared in terms of particle size and chemical specifications, dosed, and mixed together to …


Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh (0.074 mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.


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.

In pelletizing plants that operate with wet grinding to reduce the particle size of the ore prior to the balling/pelletizing process, it is necessary to dewater the slurry exiting the grinding mills to lower the moisture content in the ore. The pelletizing of iron ore normally requires from 8% to 10 % moisture depending on the ore characteristics.


Pellet Plant Process. Raw material iron ore fines are fed to Iron ore grinding system (IOGS – 160 t/h) for grinding the ore to 85% -200 mesh. We use the wet grinding process for this. The slurry produced is then fed to filter press.
