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.

Ore Dilution & Recovery in Mining
Under the conditions on the Gogebic iron range, Michigan, where much of the capping carries 40 percent or more iron, a small amount of dilution does not seriously affect the grade of ore mined and the dilution from this source may offset tonnage of ore lost; the net result is therefore likely to be approximately 100 percent tonnage recovery ...
