On the one hand, developed Western countries have listed non-metallic minerals as strategic reserve resources. On the other hand, China's large number of non-metallic minerals are inefficient in mining and even exported cheaply, which is currently an awkward situation faced by the domestic non-metallic mineral industry. An official of the State Taxation Administration recently said that for some non-metallic mineral resources that are irreplaceable in industry and national defense, the state plans to fine tune the resource tax on some non-metallic minerals next year to strengthen protection and guidance. On December 20th, under the leadership of the Foreign Trade Department of the Ministry of Commerce, the "Seminar on the Development of Non metallic Mines in China" was held on a small scale in Beijing. Officials and experts from relevant national ministries and commissions have stated that non-metallic mines have reached the point where the country must introduce policies to protect and guide them. Zhang Shaohua, an authoritative expert in domestic non-metallic mineral resources and vice president of the China Africa Geoprofessions#Geological engineering Exploration and Research Institute, said that China is a big country in non-metallic mineral resources, and its reserves of many varieties rank among the world's top. For example, the production of talc in China is approximately 2.7 million tons per year, and the export of talc accounts for 30% to 35% of the total international trade. China has always been the world's largest exporter. However, some of our mineral reserves are insufficient and there are significant concerns about sustainable supply. Take limestone as an example. Almost half of the proven resources cannot be extracted and utilized. In fact, they are 'dead ores'. In addition, there is a serious waste of resources in the entire non-metallic mining industry. Yu Yantang, Director of the Expert Committee of the China Nonmetallic Mineral Industry Association, stated that many mines in China have gradually been "privatized" after restructuring, and private enterprises often adopt predatory development for short-term profits, resulting in high waste in the mining process of mineral resources. In order to obtain profits and recover investment as soon as possible, many enterprises often do not follow the rules of mining, resulting in industrial phenomena such as mining rich and abandoning poor, mining easy and difficult, mining thick and thin, and opening small mines. As a result, resources are wasted and destroyed. The average utilization rate of non-metallic mineral resources is only 20% to 30%, and some gypsum mines even have only 10%. Shen Wanci, a professor at the Department of Materials Science and Engineering at Tsinghua University, stated that modern national defense technology cannot do without non-metallic mineral materials, and an important foundation of nuclear technology is fluorine chemical technology using fluorite as the basic raw material; The stealth material of stealth fighter jets is also a composite material mainly composed of graphite and other non-metallic minerals. "The types of strategic mineral reserves in the United States include industrial diamond, fluorite, graphite, Kyanite, schistose mica, talc, Pyrophyllite and other non-metallic minerals, but China has no real strategic mineral reserves, or even a list of varieties. Experts suggest that it is necessary to reassess non-metallic mineral resources as soon as possible to identify their family background. Further clarify which non-metallic minerals in China have advantages, more abundant, insufficient, and severe shortages internationally. On this basis, provide scientific basis for planning and utilizing two types of resources, two markets, and resources. Liu Xinhua, an official of the Department of Foreign Trade of the Ministry of Commerce, said that in September this year, the non mining industry had begun to benefit from the adjustment of the national import and export tax rate for some resource products, and the original export tax rebate policy for some primary mineral products was cancelled. Liu Xinhua also stated that the country is gradually improving non-financial assets through economic means such as finance and taxation
