Some of the industrial minerals commonly used in construction, such as crushed stone, sand, gravel, and cement, are called aggregates. Industrial minerals are extremely versatile; most have at least two, sometimes many more, applications and span multiple markets. Talc, for example, is used in cosmetics, paper, and plastics.

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.
