Iron Ore Processing: From Extraction to Manufacturing
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.

Environmental Impact of Open-Pit Mining
The Mechanics of Open-Pit Mining. Open-pit mining involves the removal of large quantities of overburden (the soil and rock overlying a mineral deposit) to access the ore body. The process begins with the excavation of a large pit, which grows progressively wider and deeper until the mineral resource is depleted.
