To nullify the effect of feed size on the separation efficiency, monosized iron particles were used in this study. The feed to the KCJ was screened at a size less than the internal screen size to avoid pegging. In the present study, iron ore of size <300 micron were used as feed material. The particle size of the ragging material to be used depends on the pegging factor of the internal ...

Magnetic separation is a technique for separating iron ore from impurities on the basis of the difference in their magnetic properties. This type of separation is widely used for the beneficiation of magnetite ore. A drum with a permanent magnet is rotated in slurry and the result is that magnetite ore, which is magnetic, becomes attached to the surface of the drum and is .
