Mining and Mineral Use Earth Science

Geologists use many methods to find mineral deposits that will be profitable to mine. Ore deposits can be mined by surface or underground mining methods. Mining provides important resources but has environmental costs. By U.S. law, currently mined land must undergo reclamation. This is not true for old mines. Metal ores must be melted to make metals.

Mining and Mineral Use Earth Science

An ore is a rock that contains minerals with useful elements. Aluminum in bauxite ore ( Figure below ) is extracted from the ground and refined to be used in aluminum foil and many other products. The cost of creating a product from a mineral depends on how abundant the mineral is and how much the extraction and refining processes cost.
