low-grade manganese ores in India can be divided into the following categories from the mineral-dresser's point of view: (1) following this by magnetic separation for the removal of magnetic oxide of iron. Alter- of psilomelane and a little pyrolusite, and the gangue minerals were quartz, mica, barite, apatite, rhodonite and calcite

Strong magnetic separation. Manganese minerals are weak magnetic minerals (specific magnetization coefficient X=10×10-6~600×10-6cm3/g), can be effectively recovered in a strong magnetic field magnetic separator with a magnetic field strength of Ho=800-1600kA/m (10000-20000oe), and the grade of manganese can generally be increased by 4-10%.

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

Pyrolusite is a mineral consisting essentially of manganese dioxide (Mn O 2) and is important as an ore of manganese. It is a black, amorphous appearing mineral, often with a granular, fibrous, or columnar structure, sometimes forming reniform crusts. It has a metallic luster, a black or bluish-black streak, and readily soils the fingers.The specific gravity is about 4.8.

Based on these studies, a process flowsheet for the industrial-scale production of upgraded manganese ore has been developed.
