a. Open-Pit Mining: Open-pit mining is employed when the iron ore deposit is close to the surface or forms a large, easily accessible ore body. In this method, large-scale excavation machinery, such as excavators and haul trucks, is used to remove the overburden (surface material) and expose the ore deposit.
