Other Nonmetallic Mineral Mining and Quarrying
NAICS 212390 · United States · 2022 edition
This industry comprises establishments primarily engaged in developing the mine site, mining, and/or milling or otherwise beneficiating (i.e., preparing) nonmetallic minerals (except coal, stone, sand, gravel, clay, and ceramic and refractory minerals). Drylake brine operations are included in this industry, as well as establishments engaged in producing the specified minerals from underground and open pit mines.

Compare another operationInsurance operations research — draft
Operations in this class develop mine sites and extract nonmetallic minerals such as phosphate rock, potash, barite, borates, peat, and rock salt from open-pit or underground mines. On-site activities often include basic milling or beneficiation — crushing, screening, drying, or otherwise preparing the raw mineral for sale — using heavy equipment, conveyors, and sometimes blasting.
Questions to investigate
- Is extraction surface (open pit) or underground, or both?
- What specific minerals are being mined, and is any on-site processing or beneficiation performed beyond basic crushing and screening?
- Is blasting or explosives use part of the operation?
- Are there tailings ponds, brine evaporation ponds, or other containment structures on-site?
