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 any use and considered as waste. Such ore does not respond to any physical beneficiation techniques because of intricate microstructure and poor …

The optimum beneficiation resulted from the reduction-roasting process of low-grade manganese ore in -40+60 mesh at temperature 700°C followed by the magnetic separation process. It had improved ...

The manganese content of this type of manganese ore is very low, usually less than 30%, and the particle size of manganese ore is small and the mud content is high, so it is difficult to process.
