identify ore minerals using a reflected light microscope. 3. RESULTS AND DISCUSSION According to the results of mineralogical analysis, the manganese ore contains about 75-80% of non-ore minerals and 20-25% of ore minerals in 0.5-4.0 mm rocks. The dominant mineral was pyrolusite. The pyrolusite appears white-colored and has anisotropic
The main advantages of the electrolytic method of producing metallic manganese are producing rather pure metal (up to 99.5% Mn) and possibly processing low-grade manganese ores. As a result of the implementation of electrolytic technology, electrolytic manganese Mn997 (Mn content 99.7%) or Mn998 (Mn content 99.85%) is obtained as a commercial ...
On Earth, manganese is never found as a free metal, but it is found in a number of minerals. The most important of these minerals is pyrolusite, the main ore mineral for manganese. Manganese is essential to iron and steel production. The U.S., Japan, and Western Europe are all nearly deficient in economically mineable manganese.
