Mining And Mineral Use | Earth Science

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. Many gems are cut and polished to increase their beauty.

Extracting Ores | Mining Of Mineral Resources | Siyavula

The first iron mining techniques used charcoal which was mixed with iron ore in a bloomery. When heating the mixture and blowing air (oxygen) in through bellows, the iron ore is converted to the metal, iron. The chemical reaction between iron oxide and carbon is used here to produce iron metal. The balanced chemical equation for the reaction is:
