Iron for example, is a mineral ore that most people think of as an un resource. The truth is that Iron is only concentrated in the earth's crust in thin layers from one geologic time period. Once we deplete these layers, then we will no longer be able to mine iron ore.

Feb 24, · You can dig a pit, try to follow the metal vein in shafts, or even pick up trace amounts by letting it sift down through water. The mining technique of choice depends on the metal, its concentration, and other factors, such as the surrounding rock. Separate or purify the metal from its ore. Iron Ore, for example, is often not elemental iron. It is usually Hematite or one of many other forms.
