The mining industry consists of the search for, extraction, beneficiation, and processing of naturally occurring solid minerals from the earth. These mined minerals include coal, metals such as iron, copper, or zinc, and industrial minerals such as potash, limestone, and other crushed rocks. Oil and natural gas extraction (NAICS code 211) is not included in this industry.
As currently 70% of the world''s steel production relies on coking coal and iron ore as raw materials, it is likely that demand for coking coal and iron ore will continue to grow at a steady pace in the medium term. In the longer term, it is possible that increased recycling .
Iron and steel are used widely in the construction of roads, railways, other infrastructure, appliances, and buildings.
