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. Scanning electron microscope (SEM) analysis In ...

These machines were capable of treating 10 tons of ore a day. This process of separating magnetic substances from the non-magnetic substances in a mixture with the help of a magnet is called magnetic ...
