Non-Metallic Minerals are a special group of chemical elements from which no new product can be generated if they are melted. Nonmetallic minerals are, for example, sand, gravel, limestone, clay, and marble and gemstones. Such materials lack metallic characteristics like good electric and thermic conductivity, luster, rigor, and malleability; they are, however, essential for many industries and of high importance for Africa’s Development.
The nonmetallic minerals industry is best known for the production of cement, ceramics, glass, and lime products. Thus, the range of application is quite broad, from construction materials to sanitary ware to tableware and decorative products.
The transformation of nonmetallic minerals into these products is often an energy-intensive process, which can include several steps, such as heating, grinding, mixing, cutting, shaping and honing..
Africa Mining Vision refers to non-metallic minerals as Development Minerals.
