(2) In order to meet the stricter quality requirements of non-metallic mineral raw materials for new ceramics, engineering plastics, optical fiber and other new materials, non-metallic ore dressing will move toward high-purity and ultra-fine technology fields;
(3) Further development and promotion of high-efficiency beneficiation equipment; application and development of various mineral processing methods in the treatment of non-metallic ore refractory ore; various new technologies (such as superconducting, ultrasonic, laser, etc.) in non-metallic minerals Application in mineral processing and application of modern detection technology.
It is necessary to further understand the status and role of the non-metallic mineral industry in the national economy. Non-metallic minerals are available in a wide variety of applications and are used in almost all industrial sectors. A variety of non-metallic minerals are used, which consume far more than metals. According to statistics from relevant US departments, in 1982, the average annual industrial material consumption per person in the United States was 1,342 pounds for various metal materials, and 20,830 pounds for various non-metallic materials. In developing countries, various non-metallic minerals are also widely used in order to develop their own construction industry and other industries. In addition, the development of agriculture is also inseparable from non-metallic minerals. In short, from the perspective of the needs of the national economy and the people's livelihood, non-metallic minerals have a very important role. In the development of industry and agriculture, it is necessary to develop non-metallic mineral industries accordingly. On the other hand, in developing countries, the non-metallic mineral industry is also of special importance and importance in the national economy. A large number of non-metallic deposits are located in relatively remote areas, and the development of these deposits can promote the rapid development of these areas. Asbestos County of Sichuan Province, Sichuan Province and is with the construction of two new health asbestos mines and developed. The town of Yuya in Qinghai was also discovered because of the development of the Yanya asbestos mine. There are many good non-metallic mineral resources in China's vast land; domestic economic construction and the international market require a large amount of non-metallic mineral raw materials. The abundant resources and vast market provide unique conditions for accelerating the development of China's non-metallic mineral industry. It can be predicted that as long as the production development goes up, a larger and higher level of development of non-metallic minerals is about to come.
