the plant annually needs 27.45 lakh tones of iron ore, 24.45 lakh tones of coal, 5 lakh tones of limestone, 2.62 lakh tones of dolomite, 90,000 tones of manganese and ferro-manganese, and 40,000 tones of quartzite. the plant initially had capacity of producing 1.21 million tones of pig iron and 1.1 million tons of,iron ore–coal composite pellets/briquettes as new feed,iron ore . total iron ore resources in india are about 28.52 billion tones (bt). the total resources of hematite and magnetite in the country (as on 1.4.2010) are estimated at 17,882 mt and 10,644 mt 3. about 57% of iron ore production comes in the form of fines (including concentrates) during course of mining operations itself.
the beginning of the manganese ore processing involves a multistage crushing workflow. from there, the production of ferromanganese, the manganese ore is mixed with iron ore and carbon and then reduced either in a blast furnace or in an electric arc furnace. the resulting ferromanganese has a manganese content of 30% to 80%. pure manganese used for the production of iron-free alloys is produced by,separation of iron from manganese ores,iron ores like magnetite, chromite, and manganese ore like pyrolusite are concentrated by this. magnetic separation, magnetic separation process. magnetic separation methods. magnetic separators are widely used to remove tramp iron from ores being crushed, to such as copper crushers, manganese crushers, iron ore.
steel production, both manganese and iron ores must undergo numerous processing. manganese ore needs to be processed into alloys with high manganese content (which also includes iron). the most important of these alloys are high carbon ferromanganese (hc femn), refined ferromanganese (rf femn) and silica manganese (simn) alloys.,gold, chrome, manganese, iron ore production to continue,gold, chrome, manganese, iron ore production to continue at scaled-down level . makhosandile zulu. minister of mineral resources gwede mantashe says this will be done to allow smelters and plants
