These deposits usually occur beneath barriers like a rock layer, forests, or oceans, which makes accessing them difficult. Depending on how these ores are extracted, mining methods can be egorized as ''surface'' or ''underground'' types. In surface mining, the rock barrier on top of the deposit is removed to access the ore.
