, and utilizing of iron ore at 45% Fe as a cut off fixed by Indian Bureau of Mines, it is the need of hour to effectively beneficiate low grade iron ore. Apart from the reserves of low grade iron ore, the previous washing methodology adopted in mining industries which had discarded the slimes as well as fines containing Fe value
iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand amp; export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.
over the world, important iron ore producing countries have increased their production by initiating steps to utilize the low grade iron ores, fines, and slimes. The main difficulty in processing and utilization of low grade iron ores primarily stems from
Low grade Iron Ore Beneficiation and the Process of Jigging . Iron ore resources are getting consumed at an accelerated rate because of the growth in the production of iron and steel. Due to this reason the availability of high grade iron ore is reducing and the supply of high grade iron ore to iron and steel plants is declining sharply.
The consumption of iron ore has increased rapidly over the past decade due to the tremendous growth of the iron and steel industry. The depletion of high grade iron ore resources makes it inevitable to utilise the existing low grade iron ores/fines/tailings with proper beneficiation to meet the present specification and demand.
There is an urgent need for development of environmental friendly processes through which iron ore fines can be beneficiated and utilized effectively. For processing of low grade iron ores, ground to finer size necessitates the use of centrifugal force.
