More than 3,000 minerals are known in nature, of which over 200 are commonly used. Silicate minerals account for about 90% of the Earth’s crust, while other major groups include natural elements, sulfides, oxides, halides, carbonates, sulfates and phosphates.
Minerals play a vital role in industry. Salt, borate, barite, quartz sand and gypsum serve as key chemical raw materials; limestone and fluorite act as fluxes in steelmaking. Graphite, magnesite and refractory materials support metallurgy, and phosphate, nitrate and potash are essential for fertilizers. Many industrial minerals are also used in ceramics, grinding, oil drilling and filtration.
Non-metallic mineral powders such as calcium carbonate, kaolin, talc, silica and magnesium hydroxide are widely used as fillers in plastics, rubber, adhesives and composites. Surface modification is required to improve their compatibility, dispersion and performance in the polymer matrix.
