The study was carried out in a 4-m tonne iron ore pelletizing industry located in Odisha, India from March to December 2015. The pellet plant used travelling grate technology to convert low grade fines into value-added pellets. The slurry was received at the pellet plant from the beneficiation plant through a 220-km pipe line.

An ore is a mineral deposit that contains a metal that can be extracted using existing technological methods. Iron can be extracted from two types of iron ores: Magnetite and hematite. Magnetite is composed of iron in the form of Fe 3 O 4. Hematite is a mineral that contains iron in the form of Fe 2 O 3.
