Tööstuskivimite

Tööstuskivimite, also known as industrial rocks or industrial minerals, refers to naturally occurring rock and mineral substances that are extracted and processed for use in various industrial applications. These minerals are distinct from metallic ores and precious gemstones, as their value lies in their physical and chemical properties rather than their metal content. The extraction and processing of tööstuskivimite are fundamental to numerous manufacturing sectors.

Common examples of tööstuskivimite include limestone, dolomite, sand, gravel, clay, gypsum, salt, and various types of silica. Limestone and dolomite, for instance, are vital in cement production, agriculture for soil amendment, and in the steel industry as fluxing agents. Sand and gravel are essential aggregates for concrete and road construction. Clay is used in ceramics, bricks, and as a filler in paper and plastics. Gypsum is a key component in plasterboard and cement.

The economic importance of tööstuskivimite is substantial, forming the basis for many industries. Their availability and proximity to manufacturing centers often influence the location of industries. Processing typically involves crushing, grinding, screening, and sometimes chemical treatment to achieve the desired particle size and purity for specific applications. Environmental considerations are also important, focusing on responsible extraction, land reclamation, and minimizing dust and noise pollution during mining operations.
