Hydrometallurgical Processing of Manganese Ores A Review

The production of manganese alloy from manganese ore is an energy intensive process and therefore, apart from manganese ore, power plays an important role in the production of ese alloy. There are basically two mangan processes for the manufacturing of the alloy using either one of high, medium or low grade ore, viz; Blast fur

Concentration of Ores. An ore of a metal is an impure source, this means other than the metal it consists of many other impurities such as sand, grit, clay, rocks etc. These impurities are collectively known as gangue. Gangue is generally commercial valueless and we must separate it from the ore. This entire process is the concentration of ores

(d) The main ore of manganese, pyrolusite, is mainly MnO2. A solution of SnCl2 can be used to estimate the percentage of MnO2 in a sample of pyrolusite, using the following method. A known mass of pyrolusite is warmed with an acidified solution containing a known amount of SnCl2.

Pyrolusite

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.The specific gravity is about 4.8.
