4 Problems in development and utilization
Since the application of diatomite resources in my country in the 1950s, the comprehensive utilization capacity of diatomite has gradually improved. Although the industry has achieved considerable development, it is still in its infancy. Its basic characteristics are low technical level, low product processing level, single market, small enterprise scale, and resource-intensive extensive operation. gap.
(1) Low comprehensive utilization of resources. my country has large reserves of diatomite resources, especially Jilin Baishan diatomite is famous for its good quality. Grade I diatomaceous earth (SiO2≥85%) in Baishan City accounts for about 20% to 25% of the total, and Grade II and III soil account for 65% to 70% of the total. Class II and Class III soil are located on the upper and lower layers of Class I soil. At present, due to the limited market demand and technical level, the utilization of Class II and Class III soils is low. As a result, mining enterprises mainly mine Class I soil, and use Class II soil instead. , Class III soil is not mined, resulting in a large amount of Class II and Class III soil being abandoned in the mine layer. Due to the collapse of the mine layer, if the Class I soil is exhausted and the mining of Class II and Class III soil is returned, the mining difficulty will be more difficult. Larger mining costs will be higher, the comprehensive utilization rate of resource development will be low, and a unified and standardized overall design of resource protection development has not been formed.
(2) The industrial structure is unreasonable. The production enterprises are mainly small-scale private enterprises. There has not yet been a diatomite processing and product enterprise group with a large market share nationwide, and a large-scale and intensive production method that meets the requirements of modern market economy and social development has not yet been formed. , Is a resource development enterprise.
(3) The product structure is unreasonable. Diatomite enterprises still focus on the production mode of raw material mining and preliminary processing, and the product filter aid is the main product. The product convergence is serious, which has led to the oversupply of products. The proportion of deep-processed products with high technical content is relatively small, and exports are still mainly raw ores and primary processed products, which cannot fully meet the development requirements of modern high-tech and new materials industries, and their market competitiveness is poor.
(4) Technology and equipment are backward. my country’s diatomite deep processing technology and technical equipment are relatively backward, the processed products are of low grade, and cannot meet the performance indicators of similar foreign products, and the phenomenon of resource waste and ecological damage is serious.
(5) Research and development are lagging behind. New diatomite materials, especially environmental and health functional materials, energy materials, biochemical functional materials, etc., have a small number of varieties, and have a large gap between their functional performance and foreign advanced products, and the technology and product standards are backward. Over the years, the state has invested little in the non-metallic mining industry and the level of technological research and development has been low. Most diatomite companies have no R&D institutions, lack of R&D personnel, and weak basic research work, which restricts the development of the diatomite industry.
5 .Development and utilization countermeasures and suggestions
(1) Improve the comprehensive utilization of diatomite and tap potential markets. Comprehensive utilization of resources is the internal driving force to promote the development of the industry. It puts forward mandatory requirements for the comprehensive utilization of level II and level III diatomite resources, taps the potential of advantageous resources such as diatomite, expands the scope of application, and improves the level of application. Restrict the export and processing of raw diatomite ore and promote the sustainable development of the diatomite industry.
(2) Optimize the industrial structure and promote the integration of mining enterprises. Adjust and optimize the industrial layout, introduce development strategic investors, and promote resource integration of mining enterprises. Through the construction of green mines, small enterprises with backward technology and low added value of products will be gradually eliminated, and the optimal allocation of diatomite resources and the optimal combination of industrial development factors will be promoted.
(3) Strengthen product scient
ific research and promote product upgrades. Support and encourage the technological transformation and product upgrades of leading
(4) Improve the introduction of talents and cultivate incentive mechanisms. School-enterprise alliances, enterprise-enterprise alliances, accelerate the introduction and training of high-level innovative talents, and cultivate a pioneering scientific research team with solid basic theory, profound academic attainments, the courage to pioneer and innovate, and a reasonable structure and full of vitality. industrial enterprises to increase the added value of their products. Innovate the potential market of diatomite, promote fine production, intensive processing, form a diatomite system industry chain, extend and expand application areas, and promote greater synergistic benefits.
