Study On Pulp Grade Of Iron Ore Concentrate By Monte Carlo

When the particle size is 7%, the normalized value of the count rate tends to be flat. For iron concentrates with a particle size of 7%, the size of the iron concentrate cannot be distinguished by the counting rate. Before the particle size is 7%, the particle size shows a linear growth trend with the change of the normalized value. 3.4.

Effect Of Particle Size On Reduction Behavior In Iron Ore ...

When the iron ore particle size decreased to 38 µm, almost the whole reduction of the iron ore achieved at 1200°C. The X-ray diffraction analysis of this mixture showed that metallic iron phase occupied an important position in the residue. This indicated that the iron ore particle size of 38 µm was sufficient to complete the reduction. 3.2.

Iron Ore Concentrate

Magnetic techniques also are used. The upgraded ore, or concentrate, is in the form of a very fine powder that is physically unsuitable for blast furnace use. It has a much smaller particle size than ore fines and cannot be agglomerated by sintering. Instead, concentrates must be agglomerated by pelletizing. Ario Iron Ore Concentrate Specifications
