The development and utilization of non-metallic minerals has reached more than 250 kinds (2005), far more than metal minerals, and its application fields are still expanding. Non-metallic minerals are not only the basic raw materials for the development of building materials, ceramics, chemicals, light industry and agriculture, but also play an extremely important role in metallurgy, transportation, machinery, energy, environmental protection, medical medicine and defense industry. Yes, non-metallic minerals have irreplaceable advantages in the development of high-tech industries, and have become important raw materials or ingredients for new materials (engineering ceramics, etc.), aerospace, light-guide communications, superconductors, lasers, and electronic information engineering. Therefore, the exploration and development of non-metallic minerals is of paramount importance.
Non-metallic deposits have been classified according to the type of ore-forming geological and ore-bearing construction types, but there is no complete classification of industrial types. According to the definition of the type of deposit industry mentioned above, the genesis of the deposits On the basis of the classification of mineral deposits combined with minerals and mineral-related development and application conditions, it is classified as a non-metallic deposit industrial type. Because it already has the content of the deposit, it is no longer the genetic type of the deposit, and it is now in accordance with the Mineral Resources Industry Requirements Manual. National industrial standards for non-metallic ore geological exploration specifications such as pyrite, etc., based on the relevant materials of the provinces (regions) and other non-metallic mineral reserves, list the major non-metallic deposit industry types in China, some of which The types of deposits of non-metallic minerals (such as bentonite , refractory clay, etc.) have certain adjustments, trade-offs and modifications, and the deposit examples have also been supplemented.
