Ore petrography of low-grade siliceous manganese ores

01/11/2011  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.

Indian Iron Ore Scenario : Low Grade Iron Ore Beneficiation

Wide reserves of iron ore is found in India which is the basic raw material for iron and steel industry. Draft National Steel Policy 2012 of India envisages the ambitious goal of the nation to reach a production capacity of 300 Mt/yr of crude quality steel by 2025 - 26. So the corresponding demand of iron ore containing 62 - 64 % Fe would be around 490 Mt (excluding our export requirement). To ...

Iron ore - Wikipedia

Iron ores are rocks and ... Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated ...
