This major group covers businesses primarily engaged in mining, quarrying, developing mines, or exploring for nonmetallic minerals, except fuels. It includes operations that extract materials such as stone, sand, gravel, clay, and chemical minerals. Many establishments also perform related preparation activities like crushing, grinding, washing, or concentration of raw materials.
Companies that both mine and manufacture products such as cement, lime, or finished stone materials are classified based on their primary activity. For example, cement production is categorized under manufacturing, while the extraction and preparation of raw materials fall under this mining group. The sector supports industries producing construction materials, ceramics, fertilizers, and industrial minerals used in a wide range of applications.
