Iron ore mining is carried out by open cast method through manual, semi-mechanised and mechanised operations. Generally, mining is done by digging the ore with pick axes, crowbars, chisel, and spades. The mined material is screened manually to separate +10mm float ore which is stacked separately. The waste is backfilled into the pits.
