Among them, 34 mines were in the public sector and 262 in the private sector. Mining leases of iron ore provides average daily employment to around 42,049labours. 2 Iron ore mines in India are mostly mechanised mines. It is seen that extracted iron ore is further transported to the crusher unit for processing.

Open-pit mining differs from quarrying (with the possible exception of iron ore) in that the valuable mineral constitutes only a small proportion of the total tonnage of rock produced. In quarrying, the rock itself is the valuable commodity, with virtually all of the raw rock that is won being processed (often only by crushing and screening) to ...
