Mining of Iron Ores - IspatGuru
Open pit and open cut mining are the least expensive techniques for the ore extraction. Overburden and stripping ratios are important in determining whether a deposit is to be mined. The stripping ratio describes the unit of overburden that must be removed for each unit of crude ore mined. A typical open pit iron ore mine is shown in Fig 1
