Nickel Mines

The fraction of nickel in pentlandite (nickel ore) is only 5.5 × 10 −3 g Ni/g ore. To supply 1 g of pure nickel to an industrial process requires that at least 181 g of pentlandite be dug. If the nickel mine is underground, the upper layers of topsoil and clay are also excavated, perhaps a forest is also cut and biotic material degraded.
