Beneficiation of a low grade magnetite ore from Jharkhand area

Abstract

There has been a tremendous increase in demand for iron with the rise in industrial applications in the global scenario for industrial development. The fast depletion of the high grade iron ores and the increased demands of the industry puts a strong focus on assessing the exploitation of lean ores. Low grade iron ore is being beneficiated to enhance its iron content upto the desired level of industrial specification required for the different end industrial use. A low grade magnetite ore of mine reject from Jharkhand area was taken up for beneficiation to assess the possibility of upgrading the iron content to the maximum possible extent, so that it may find the better place in industrial use. Beneficiation test work could enhance the Fe(T) to 67.42% Fe(T) with a Fe(T) recovery of 64.8% and Specific Gravity over 4.7 with high magnetic susceptibility which meets the industrial specification for heavy media separation and possesses the quality of media reclamation at low intensity magnetic separation. This paper highlights the importance of beneficiation and utilization of low grade ores thereby promoting mineral conservation and national growth.
