Different physical beneficiation techniques like gravity and magnetic separation were employed for the possible separation of the ore-gangue phases for their utilization and the results reported. The results reveal that a feed having 23% Mn could be upgraded to more than 39.3% Mn by using a dry belt-type magnetic
