Low grade ore. Low grade ore is a term applied to iron rich rocks with cut off grades in the range of 25 30 Fe. It was the main supply of iron ore for many centuries of the World's early history of production of iron. Since the 1950s North America's main supply has been low grade ore.Iron ores were simply crushed and shipped as lump ore for iron making. However, with decreasing ore grades in existing high grade deposits and exploration of new lower grade deposits, the need for additional beneficiation steps is on its way to becoming the new standard for the iron ore industry.

It is to inform you that in the recently held e auction process, state government sold around 2.1 million tonnes of iron ore out of which 1.44 million tonnes of ore was purchased by us.
Mineral resources can be divided into metal, the non metal and combustible organic mineral from the perspective of the industry. Except for purity iron ore with little percentage, most of the minerals need to be processed before they can be used because some iron ores are kind of low grade. While the main method of processing is beneficiation.The efficiency of iron recovery is 90 95 (as against 70 75 in the conventional beneficiation plants) the left over Fe in the tailings is only 10 15 (as against 35 45 in the conventional beneficiation plants). In the process, low grade iron ores are dry ground, preferably to their liberation size passed through a fluidized bed roaster.
