The Answer = Smelting When carbon is added to Iron Ore at high temperatures and in the presence of added oxygen from an external source (i.e. a blower or fan), it reacts with the added oxygen to form CO2 (Carbon Dioxide) and CO (Carbon Monoxide). These molecules then react with the oxygen in the iron ore and leave pure iron.

the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden. The use of heavy machinery, usually bulldozers and dump trucks, is the most common means of
