In recent years, with the rise of new material industry, China's non-metallic mining industry ushered in a rare opportunity for development. However, as a large non-metallic mining industry in China, many non-metallic mines are still at the low and mid-level development level, seriously restricting and affecting the development of the non-metallic mining industry as a whole.
So, what is the current development status of non-metallic minerals in China and how to realize the "breakthrough" upgrade driven by the new material industry? At the recent "China Non-metallic Mineral Industry and Capital Matchmaking 2017", China Mining Daily Reporter interviewed China University of Geosciences (Beijing) Associate Professor, China Green Building Materials Industry Alliance National non-metallic mineral special committee Du Gaoxiang.
As a famous expert and scholar in non-metallic mineral field, Professor Du Gaoxiang paid special attention to the development of non-metallic mineral industry in recent years. He initiated the establishment of China's green building materials industry development alliance of the National Non-metallic Minerals Commission and the "mine babe" investment and financing docking platform, aimed at technical and financial aspects of non-metallic mineral industry to solve outstanding problems.
China Mining News: Compared with the metal mining industry, China's non-metallic mineral industry lineup is relatively large, sometimes with other industries there is a cross. In your opinion, what are the specific categories of non-metallic minerals and mineral materials in China?
Du Gaoxiang: Non-metallic mineral mining refers to not to extract the purpose of the exploitation of various types of mineral resources, belong to the category of resources, mainly contains more than 80 kinds of minerals. Bulk minerals include: graphite, quartz, kaolin, calcium carbonate, talc, feldspar, mica, fluorite, magnesite, wollastonite, bentonite, diatomaceous earth, dolomite, barite, perlite, gypsum, asbestos More than a dozen minerals. Special functional minerals include: zeolite, tourmaline, sepiolite, attapulgite, brucite, medical stone, illite, Iraqi Mongolia clay and so on.
Bentonite, also known as universal soil, Guanyin soil, widely used in metallurgy, oil drilling mud, paper, plastics, rubber and other fields. High-end products are: pharmaceutical-grade, cosmetics-grade high-purity montmorillonite, montmorillonite gel, organic bentonite, nano-bentonite, feed grade bentonite, and activated clay, bentonite waterproof blanket.
Based on the characteristics of these non-metallic ores, the directly-used materials obtained through special processing are as follows: - Powder adsorbent (bentonite, sepiolite, illite, attapulgite, Rectorite, diatomaceous earth, etc.), friction materials (serpentine, diatomaceous earth, quartz powder, garnet and the like), photocatalyst (titanium dioxide loaded with diatomaceous earth, bentonite and opal), antibacterial mineral composite powder, ; Organic polymers / non-metallic mineral products - diatomaceous earth (calcium carbonate) non-woven fabrics, household plastic rubber products, fabric / non-metallic mineral products, artificial stone.
China Mining News: China's non-metallic mineral and mineral materials in the future how to develop?
Du Gaoxiang: China's non-metallic minerals and mineral materials to achieve long-term development, we must adhere to innovation-driven strategy, in close connection with the country's new materials strategy, focusing on key technologies to strengthen scientific research, accelerate the application of achievements. In line with the country's "One Belt, One Road" construction, insist that the industry go global and actively participate in global competition. At the same time, it is necessary to give full play to the advantages of "Internet +" and realize the in-depth integration of information technology and various industries and change the mode of economic growth and industry competition. Can be said that the future of non-metallic minerals industry, cross-border competition will become the new normal.
