  ABSTRACT: The low-grade siliceous manganese ores from Bonai-Keonjhar belt, Orissa, India was mineralogically characterized and investigated for their possible upgradation. Different physical beneficiation techniques like gravity, magnetic separation etc. were employed and results reported. The results reveal that a feed having 26% Mn could be upgraded to more than 45% Mn by using a dry belt type magnetic separator with 69% recovery at 1.00 tesla magnetic intensity at finer sizes.
