What Are the Main Uses of Iron Ore?

The transport of iron ore by way of railway or freight requires a highly stable infrastructure for the mining production to be economically feasible. As a result, the mining of iron ore has remained in the control of a few major companies. Iron ore is the main ingredient in steel, which makes up 95 percent of the metals used in the world per year.

Basics of an open pit mine - Mine Engineer.Com

The definition of a open pit mine is "an excavation or cut made at the surface of the ground for the purpose of extracting ore and which is open to the surface for the duration of the mine’s life." To expose and mine the ore, it is generally necessary to excavate and relo e large quantities of waste rock.
