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.
Bulk Iron Ore. Iron Ore is a rock containing iron-rich compounds and forms the basic raw material in the manufacture of steel and iron products..
