Iron ore mining is relatively simple compared to other minerals and metals that require underground tunnels and complex chemical-drive processes, like gold. Iron ore is generally sourced from open pits on the planet's surface and typically requires only crushing before it is ready for the smelter. Like most mining, It all starts with a bang.

The first steps of copper processing are the same for both ores: mining and transporting. Copper mining is usually performed using open-pit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted ...

The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.

Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.

For the iron ore mine, the initial exploration drilling was done on a 100 m × 100 m grid in order to cover the major outcrop. The orebody was found to be complex; therefore, the 100 m × 100 m grid was then reduced to a 50 m × 50 m grid in order to obtain sufficient information below the ground surface.
