India's total iron ore production for 2019 was 231 million tons, approx. 90 percent of which was used in domestic steel production. Hematite and magnetite are the iron ores mainly found in India. Thanks to its high quality and lumpy properties, hematite is the most sought-after iron ore for the local steel industry.

Crushing is typically a dry operation that is performed in two- or three-stages (i.e., primary, secondary, tertiary crushing). Lumps of run-of-mine ore as large as 1.5 m across are reduced in the primary crushing stage to 10–20 cm in heavy-duty machines. In most operations, the primary crushing schedule is the same as the mining schedule.
