Exploration: Finding minerals | Mining of mineral …

Ore is removed from the crust by mining, either on the surface (open pit mining) or underground (shaft mining or room and pillar mining). Some minerals can be used in their natural form, for example sand in the building industry, phosphate rock for fertilisers and diamonds in jewellery.

Iron I

In iron formations, the amount of iron has been concentrated by weathering and leaching of non-iron minerals, such that we only use the term "iron formation" for rocks that contain >50% iron. The ore (iron) is concentrated by downward percolating water, and occurs in places where downward flowing waters are guided and converge, such as along a slanting layer of impermeable rock below.
