Abstract

Two strategies have been chosen for the exploitation of El-Gedida high-Mn iron ore containing 46.37 wt.% Fe and 7.53 wt.%Mn. The first one included magnetic roasting and subsequent low intensity magnetic separation. The second strategy involved a blend process of the El-Gedida high-Mn iron ore with the Um Bogma manganese ore. The magnetic separation failed to reduce the Mn content up to 4 wt.% and produced iron concentrate containing 52.15 wt.% Fe with a recovery of 94.47% and 6.45 wt.% Mn with a recovery of 71.95%. At this point, the magnetic separation is considered to be unsuitable process for upgrading the high-Mn iron ore. Moreover, this physical separation supported the microscopic prediction regarding the difficult liberation of iron minerals from manganese phase during the comminution process. On the other hand, blending the high-Mn iron ore with the Um Bogma manganese ore at weight ratio of 1/6 (El-Gedida sample/Um Bogma sample) produced a suitable mixture for making the ferromanganese alloys.
