    7/10/2017· The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing

    7/10/2017· The iron ore pelletizing process consists of three main steps: 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 feed the pelletizing process;

  • A Look at the Process of Pelletizing Iron Ore for Steel

    Preparing Iron Ore for Pelletizing (Balling) Iron ore must go through a lengthy pre-processing stage before it can be pelletized a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.

The particle size of iron ore in the ore slurry is less than 45 micro meter for around 80 % of the particles. Additive materials (such as dolomite, limestone, lime or olivine etc. depending on the quality of the pellet to be produced) is added to the slurry.

  • The Iron Pelletizing Process: Part One :: Total Materia

    The pelletizing process is a process which contains numerous sub-processes, or process segments. On the way from the mine to a final product, the iron ore goes through the following main process segments: 1) The iron ore is crushed and the waste rock is removed. About 85 % of the particles should be less than 44 μm (in length, width, or height).

    The pelletizing discs used for agglomerating iron ore concentrates into pellets are remarkable for their very narrow particle size distribution with a target size of 10 to 14 mm, important for DR-Processes: “It is the direct iron ore reduction process, enabled by those uniform size pellets, which finally leads to the tremendous reduction in greenhouse gases.

  • Pelletizing Wikipedia

    Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces. They typically contain 64–72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.
