Manganese is a versatile element and has several industrial and biological applications. Derived from ores, Manganese possesses the ability to form numerous stable stoichiometric oxides, MnO, Mn2O3, Mn3O4, and MnO2, as well as metastable Mn5O8, that could either coexist or gradually become interconvertible from one form to another during the oxidation process.
Similarly, the gradual removal of Oxygen, step by step, from the higher Oxides of Manganese leads to obtaining various types of useful lower Oxides.
Hitherto, PIT TYPE batch furnaces, and ROTARY TYPE continuous furnaces were being used to produce MnO from ores containing MnO2, which faces cumbersome operations like quenching, scrapping, etc. while the materials are subjected to Decomposition/Reduction processes.
INVOLUTE METAL POWDER TECHNOLOGIES, to overcome such cumbersome process requirements has developed its proprietary TUNNEL FURNACE route, to produce MnO from MnO2 (in various forms), as well as to produce any intermediate desirable Oxide form, varying its process parameters in the same furnace.
This high-temperature TUNNEL FURNACE, also is capable of obtaining Mn in metallic form, through the Carbothermal reduction of such Oxides, quoted Mr. S. Mohanty, Chief Consultant of Involute Metal Powders. The company has been devising and inventing processes for various ferrous/non-ferrous metal powders for the last three decades.
Involute process presently has conceived designs to produce MnO from MnO2 to the extent of 5 t.p.d to 50 t.p.d, capacity plants. A fairly large-sized Pilot plant of Involute has so far conducted and demonstrated the utility of such equipment to various prospective clientele. Manganese is used in several applications mainly :
In Steel Production as an alloying element, in the production of alkaline batteries, in Ceramics as a pigment to stain clay, and in various Fertilizers to improve crop yields.
