Industry Detail

Nonmetallic Mineral Product Mfg

The nonmetallic mineral product manufacturing subsector transforms mined or quarried nonmetallic minerals (such as sand, gravel, stone, clay, and refractory materials) into products for intermediate or final consumption. Processes used include grinding, mixing, cutting, shaping, and honing. Heat often is used in the process and chemicals are frequently mixed to change the composition, purity, and chemical properties for the intended product. For example, glass is produced by heating silica sand to the melting point (sometimes combined with cullet or recycled glass) and then drawn, floated, or blow molded to the desired shape or thickness. Refractory materials are heated and then formed into bricks or other shapes for use in industrial applications.

This subsector includes establishments that manufacture products (such as bricks, refractories, ceramic products), glass, and glass products (such as plate glass and containers). Also included are cement and concrete products, lime, gypsum, and other nonmetallic mineral products including abrasive products, ceramic plumbing fixtures, statuary, cut stone products, and mineral wool. The products are used in a wide range of activities from construction and heavy and light manufacturing to articles for personal use.
