This research is aimed at the up gradation of indigenous Pakistani iron ore Dilband iron ore hematite by utilizing common metallurgical processes First the magnetic properties of the ore were determined Initially the iron ore samples contained 34 wt % Fe in addition to other gangue materials Therefore the ore was subjected to a high temperature
The slurry is fed to the inner surface of the drum by the feeding device and rotates with the drum driven by the centrifuge drum In a very short period of time the large density ore particle group centrifuge settled to the inner surface of the centrifuge drum and the compacted thin layer of particles rotated with the drum
Despite the difficulties in pelletizing specularite type refractory iron ores the utilization of these resources is indispensable for the steel industry due to the increasing need for iron This study investigated Fe recovery from a refractory iron ore using gravity separation reverse flotation and two stage magnetic separation
Iron ore pelletization is an oxidizing process for the agglomeration of fines or ultra fines lower than a size of 150 μm of the iron ore concentrates with a low concentration of gangue roasting magnetic separation showed comparatively superior pellet quality than the hematite pellet generated by magnetic separation of the BHQ ore The
The Iron ore under investigation is a low grade Iron ore according to the weight percentage of 15% % of the Iron ore obtained by EDS The XRD pattern of the ore was also analyzed with X pert HighScore plus software figure 1 and the result was in agreement with titanomagnetite reference number ICCD 01 074 2034
