Industry Group 2123

NAICS 4 digit Industry Group 2123 – Nonmetallic Mineral Mining and Quarrying

Definition of NAICS 4 digit industry group 2123: This industry group comprises establishments primarily engaged in developing mine sites, or in mining or quarrying nonmetallic minerals (except fuels). Also included are certain well and brine operations, and preparation plants primarily engaged in beneficiating (e.g., crushing, grinding, washing, and concentrating) nonmetallic minerals.

Beneficiation is the process whereby the extracted material is reduced to particles which can be separated into mineral and waste, the former suitable for further processing or direct use. The operations that take place in beneficiation are primarily mechanical, such as grinding, washing, magnetic separation, and centrifugal separation. In contrast, manufacturing operations primarily use chemical and electrochemical processes, such as electrolysis and distillation. However, some treatments, such as heat treatments, take place in both the beneficiation and the manufacturing (i.e., smelting/refining) stages. The range of preparation activities varies by mineral and the purity of any given ore deposit. While some minerals, such as petroleum and natural gas, require little or no preparation, others are washed and screened, while yet others, such as gold and silver, can be transformed into bullion before leaving the mine site.

Four Digit Industry Group Breakdown for North American Industry Classification System

NAICS codes are broken down by digit. The broadest description starts with the 2 digit sector codes. The 3 digit subsector codes are more specific, then the 4 digit industry group (Where you are now), 5 digit industry, and the most specific is the 6 digit NAICS code. If industry group 2123 does not describe the industry of the business in question, then select the largest applicable code below. From there, follow through the progression of smaller digits to the larger digits in order to obtain the most specific 6 digit classification.
