Taconite is a lowgrade iron thought to be of little value, taconite was considered overburden waste in the days when high grade iron ore was iron content, magnetite, is only 20 30 compared to 50 60 iron content in red ore is also referred to as direct shipped ore because it can be shipped without processing.
Nowadays, steel industry develops rapidly. However, lots of iron ore needed by China's steel industry are imported from abroad. China's dependence on foreign iron ore exceeds 70%. As a result, not only have large amounts of foreign currencies been spent but also a potential threat has been posed to the economic development of our country.
iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand 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.
