Tööstusmineraalid

Tööstusmineraalid are naturally occurring substances, primarily of mineral origin, that are extracted and processed for commercial use in various industries. They differ from metallic ores in that their value lies in their physical or chemical properties rather than their metal content. Common examples include limestone, gypsum, clay, silica, and feldspar. These minerals are essential raw materials for a wide range of manufacturing processes, from construction and ceramics to glass production and chemical manufacturing.

The extraction of industrial minerals often involves mining, which can be done through open-pit or underground methods, depending on the geological setting and the depth of the deposit. Once extracted, these minerals are typically processed to remove impurities and achieve the desired particle size and form. This processing can involve crushing, grinding, screening, flotation, and chemical treatments. The specific applications of industrial minerals are diverse. Limestone, for instance, is a key ingredient in cement and concrete, as well as in the production of lime for agriculture and industrial processes. Gypsum is crucial for producing plaster and drywall. Clays are used in ceramics, bricks, and as fillers in paper and plastics. Silica is a primary component of glass and is also used in foundries and as an abrasive. Feldspar is another important component in glass and ceramic manufacturing. The availability and accessibility of these mineral resources significantly influence industrial development and economic activity in many regions.
