But How is Iron Ore Mined? 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.

The extraction of silver ore is a complex process. It begins with drilling and blasting to break up the rock containing the silver. This ore is then transported to a processing facility where the real magic begins. Separating Silver from Ore. At the processing plant, the ore undergoes a series of crushing, grinding, and beneficiation processes.

Once the ore supply cannot yield enough gold to mine (either physically or economically), operations halt, and the mine is decommissioned. Closing a gold mine is a complicated affair. Responsible gold mining companies generally monitor and upkeep the non-productive mine site to ensure that the rehabilitation of the land is successful.
