The U.S. 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.
It is pertinent to note that out of the total land area of the country (3.29 million sq. kms.), the area leased out of mining, as on 1.9.94, was 7126.13 sq. kms. Comprising about 9,213 mining leases excluding atomic minerals, minor minerals, petroleum and natural gas this constitutes only about 0.25 per cent of the geographic area of the country and that including atomic minerals and .
For example, using surface mining techniques, many mining operations are now able to extract over 85 percent of minerals and 98 percent of metallic ores — without digging a shaft or endangering the lives of workers. Newly-developed machines used for grinding and crushing can extract minerals from the earth with less energy than ever before.
