The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional beneficiation techniques used to …

Scheele first chemically characterised graphite in 1779, and A. G. Werner later gave it the term "graphite," which was derived from the Greek word "grapho," which means "I write" [].There are many different physical and structural forms of carbon that exist in nature [].
