Pyrolusite

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 bluishblack streak, and readily soils the fingers.

Manganese Concentration From Pyrolusite. Jan 15, 2012183; Analysis and chemistry of a manganese ore? A 0.200 g sample of the ore pyrolusite composed mainly of MnO2, is analysed in order to determine the percentage of manganese in the sample. To the ground ore 50.0mL of 0.100 M solution iron (ii) ammonium sulfate is added in order to reduce MnO2 to Mn2+.

Concentration of Ores Study Material for IIT JEE

Gravity Separation or Hydraulic Washing (Levigation) Generally oxide and carbonate ores are concentrated by this method. i.e. haematite and cerussite. There are two gravity concentration methods. Jigging It is removal of the lighter portions of an ore by means of a stream of water or air which rises through a bed of coarse ore particles.
