Nonmetallic Mineral Product Manufacturing

The Nonmetallic Mineral Product Manufacturing subsector is based on the transformation of 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. It has no schema of its own: companies here are mapped on the Manufacturing schema, and what it does not cover is recorded as gaps.
