Two low-grade siliceous manganese ores such 1) siliceous crystalline and 2) siliceous cherty types from north Orissa, India was mineralogically characterized and investigated for their possible upgradation. Both the Mn-ore types were subjected to different physical beneficiation techniques under identical conditions and results reported.

manganese minerals like lithiophorite (~CoO: 1.2%) and cryptomelane (~CoO: 0.2%). A feed of low-grade siliceous manganese ore containing 26% Mn and 32% SiO 2 and 0.08% Co was subjected to physical beneficiation. By processing the low-grade siliceous ore on a dry belt

for beneficiation of low grade manganese ore, containing siliceous matter as a major gangue material, by the froth flotation method. These authors have recommended the use of 0-5 lb. of oleic acid as collector for pyrolusite, 0-6 lb. of sodium silicate as depressant for silica and 0.2 lb. of eucalyptus oil as frother per ton of the ore.

Froth flotation is the process generally recommended for the beneficiation of low and medium grade ores because of the floatability characteristics of the manganese. The present work has been taken with waste Manganese ore from Garividi mines (Vizianagaram District). Manganese ores of major commercial importance are pyrolusite (MnO 2, Mn about ...

Siliceous manganese ore, associated with the banded iron formation occurs in large volume in northern Odisha, India. It is a sub-grade ore containing 21% Mn, 60% SiO 2 and 3% Fe, hence do not find ...

Low grade siliceous manganese ores from the iron ore group of the Bonai-Keonjhar belt, Orissa, India are found mostly in shear zones. The ore characteristics of siliceous manganese ore samples from three different mines, viz. the Shankar (Barbil OMC lease hold area), the Sone-Patuli (Patmunda, OMM lease hold area), and the Musaghar (Roida, OMDC lease hold area), were studied.
