Iron Ore Mining

Establishments in this category are primarly engaged in (1) developing mine sites, mining, and/or beneficiating (i.e., preparing) iron ores and manganiferous ores valued chiefly for their iron content and/or (2) producing sinter iron ore (except iron ore produced in iron and steel mills) and other iron ore agglomerates.

Other Crushed and Broken Stone Mining and Quarrying

This includes: (1) establishments primarily engaged in developing the mine site and/or mining or quarrying crushed and broken stone (except limestone and granite); (2) preparation plants primarily engaged in beneficiating (e.g., grinding and pulverizing) stone (except limestone and granite); and (3) establishments primarily engaged in mining or quarrying bituminous limestone and bituminous sandstone.

Illustrative Examples:

Bituminous limestone mining and/or beneficiating
Marble crushed and broken stone mining and/or beneficiating
Bituminous sandstone mining and/or beneficiating

Support Activities for Nonmetallic Minerals (except Fuels) Mining

This includes establishments primarily engaged in providing support activities, on a contract or fee basis, for the mining and quarrying of nonmetallic minerals (except fuel) and for the extraction of nonmetallic minerals (except geophysical surveying and mapping, site preparation, construction, and transportation activities). Exploration for these minerals is included in this industry. Exploration services include traditional prospecting methods, such as taking core samples and making geological observations at prospective sites.

Engineering Services

Establishments in this category are primarly engaged in applying physical laws and principles of engineering in the design, development, and utilization of machines, materials, instruments, structures, processes, and systems. The assignments undertaken by these establishments may involve any of the following activities: provision of advice, preparation of feasibility studies, preparation of preliminary and final plans and designs, provision of technical services during the construction or installation phase, inspection and evaluation of engineering projects, and related services.
