Beneficiation of manganese ores with particular reference

manganese. Braunite is sometimes found in many cherty, siliceous manganese oxide ores and this mineral containing 10% silica behaves as the oxide minerals in treatment. A group of oxide manganese ores characterised by the impregnation of chert, chalcedony, or opal, by psilomelane or pyrolusite may be classified as silicate ores.

Prereduction and magnetic separation of low grade

low-grade manganese ores, which contain iron oxide, may be upgraded by prereduction and magnetic separation. In this study, ferruginous low-grade manganese orewas prereduced by CO, which converted iron oxide to Fe. 3. O. 4. while manganese oxide was reduced to MnO. Then, the iron-rich component was collected by magnetic separation.

CN102674468A Method for preparing barium sulfate while

The invention relates to a method for preparing barium sulfate while purifying manganese sulfate. The method is characterized by comprising steps of adding sulfide into 10-400g/L manganese sulfate liquor, heating the mixture, removing impurities of the mixture, separating solid from liquid of a reaction product, and abandoning the solid; enabling the obtained liquid to react with equimolar

Barium oxide Wikipedia

Barium oxide, BaO, baria, is a white hygroscopic non-flammable compound.It has a cubic structure and is used in cathode ray tubes, crown glass, and catalysts.It is harmful to human skin and if swallowed in large quantity causes irritation. Excessive quantities of barium oxide may lead to death.
