Nagpur-based Nagpur Pyrolusite Pvt. Ltd is the leading manufacturer and supplier of manganese dioxide, manganous oxide and various ferro-alloys such as low carbon silico-manganese, medium carbon ferro-manganese, low carbon ferro-manganese, ferro-titanium, ferro-molybdenum, ferro-vanadium. In near future, the company plans to launch the following products viz. manganese sulphate, manganese carbonate, manganese acetate, chemical grade manganese dioxide, ferro tungsten, ferro niobium and other ferro alloys.
Different grades of manganese dioxide (MnO2) manufactured by the company ranges from 72 per cent MnO2 to 90 per cent MnO2. The MnO2 offered by is available in powder, granular, chip and lump form. Powder MnO2 is available in the range from 85 mesh to 600 mesh. Manganese dioxide is an essential ingredient for the manufacturing of dry cells, it is also used for decolorizing the greenish ting in glass, it is used in ferro-alloys, ceramics, pigments, paints, dyes, organic, inorganic and aromatic chemicals, and also in water treatment plant where granular MnO2 is used to remove iron from the water.
Various grades of free flowing odorless fine powder manganese oxide offered by the company ranges from 50 per cent Mn to 62 per cent Mn. Powdered MnO is available in the size range of 85 mesh to 300 mesh. Manganese oxide is used in animal feed industry, fertilizer industry, welding industry etc. Manganese is an important micronutrient, the deficiency of which disrupts growth and results in disorders of the bones and central nervous system. "As the animal body does not produce manganese, it needs to be supplemented externally," said the spokesperson from the company, while highlighting the importance of manganese.
Ferro alloys are used in the production of various grades of carbon and alloy steel. The addition of ferro alloys essentially impart certain physical and chemical properties in steel, e.g. change in tensile strength, ductility, hardness, corrosion resistance, wear resistance or abrasion resistance properties. Ferro alloys are also commonly used for deoxidization, desulphurisation and refunding of steel.
The company's two manufacturing units are located at Gondkhedi District (Nagpur) having a combined capacity of manufacturing about 1,200 metric tons/month of manganese dioxide and granules, 800 metric tons/ month of manganous oxide and about 500 metric tons/month of various ferro alloys.
The company has complete in-house integration for ore crushing, benefaction, R&D laboratory including all testing facilities etc. Serving the market over the past 23 years Nagpur Pyrolusite Pvt. Ltd. has carved out a niche, for itself in manganese dioxide and manganous oxide and ferro alloys-the major minerals and metals in which the company deals with.
