Why is there a need to crush iron ore bearing rock?

Crushing iron ore-bearing rock is a crucial step in the mining and processing of iron ore for several reasons: Liberation of Minerals: Iron ore is typically embedded within the rock. Crushing the rock helps to liberate the iron ore particles from the surrounding minerals, making it easier to process and extract the iron.
