Geology and mining — MineFacts
Ore extraction can be carried out in an open pit or underground. Ore bodies are therefore often mined in open pits down to a depth of 300 - 400 m, below which normal extraction changes to underground extraction. In Sweden, it is underground extraction that dominates, but the majority of the world's extraction is in open pits.
