what is magnetic separation in chemistry?
Limestone is a common non-metallic mineral and is a valuable resource for a wide range of uses. Limestone is the trade name of limestone as a mineral raw material. Limestone is widely used in the history of human civilization because of its wide distribution and easy access in nature. As an important building material, it has a long history of mining. In modern industry, limestone is the main raw material for the manufacture of cement, lime and calcium carbide. It is an indispensable flux limestone in the metallurgical industry. High-quality limestone is widely used after ultrafine grinding. Used in the manufacture of paper, rubber, paint, paint, medicine, cosmetics, feed, sealing, bonding, polishing and other products. According to incomplete statistics, the ratio of limestone and building stone consumed by cement production, lime production, metallurgical flux, and superfine calcium carbonate consumption limestone is 1:3. Limestone can also be used to make glass, soda ash, caustic soda, etc., iron and iron is used as a flux to remove gangue, and quicklime is used as slag material to remove harmful impurities such as sulfur and phosphorus. In life, limestone is processed into pure powdered calcium carbonate, which is used as a filler for rubber, plastic, paper, toothpaste, cosmetics, etc. In agriculture, lime, sulfur mixture, Bordeaux mixture and other pesticides are prepared with quicklime. The application of slaked lime in the soil neutralizes the acidity of the soil, improves the structure of the soil, and supplies the calcium required for the plant. Protect the trees by brushing the trunk with lime. The chemical industry uses limestone chemical processing to make calcium chloride, calcium nitrate, calcium sulfite and other important calcium salts. The limestone reserves in Xinjiang are abundant. In view of the huge economic value of limestone mining, the limestone powder processing industry has been vigorously developed in recent years. , achieved good economic benefits.
With the continuous advancement of science and technology and the development of nanotechnology, the application field of limestone is being further broadened. Limestone can be used in many fields after being crushed and processed by the mill. It has achieved considerable economic benefits. In recent years, the limestone powder processing industry has gradually become hot.
Limestone is not only an indispensable important raw material for cement and steel industry. With the development of science and technology, it is also widely used in water ash, smelting, cement, chemical, power plant desulfurization and papermaking industries, and can be used as a substitute for plastics. Packaging materials are a new type of environmentally friendly raw materials. The market demand is increasing year by year. It is one of the most dynamic environmental protection and green mineral resources in the 21st century.
According to the “China Mineral Resources Report 2016” issued by the Ministry of Land and Resources of China in 2016, during the “Twelfth Five-Year Plan” period, the reserves of cement limestone in China increased from 102.1 billion tons in 2010 to 128.23 billion tons in 2015.
Limestone reserves are widely distributed in 29 provinces, municipalities and autonomous regions except Shanghai. Among them, Shaanxi has the largest reserves in the country; the rest are Anhui, Guangxi, Sichuan (including Chongqing), Shandong, Hebei, Henan. , Guangdong, Liaoning, Hunan, Hubei and other places.
Investment opportunity analysis
At present, China's economy is in a special period of growth rate shift period, structural adjustment pain period, and “three-phase superposition” of the previous stimulus policy digestive period. The binding effect of resources, energy, safety and environmental protection on economic development is increasingly strengthened. Although many industries in China are not too prosperous, and the national economy has entered the “L” type, the projects of lime on the whole country have indeed been many and continue to be hot. Compared with many industries currently being overcapacity, there is a feeling of loftyness. From the "Twelfth Five-Year Plan" to the "Thirteenth Five-Year Plan" period, China's lime production has ranked first in the world for many years, and its output value has been growing at a high speed. It can already be called the world's lime industry leader. China's lime industry has begun to show its strongness. Development trend.
As a basic raw material for metallurgy, chemical industry, building materials, medicine, agriculture and environmental protection, lime has the characteristics of wide application range and large usage. The implementation of the new environmental protection law on January 1, 2015 has had a major impact on the lime downstream application industry. In 2017, it will usher in a tough battle to eliminate backward lime production capacity. At the same time, with the industrial restructuring of the downstream industry and the continuous advancement of energy conservation and environmental protection, the demand for lime and its deep processing will continue to grow. The industry will face new opportunities and will also bring new economic growth points and develop new ones. There will be significant business opportunities in the field of economic growth, especially in the field of serialized, refined and functionalized lime deep processing, as well as industrial waste water treatment, waste incineration, flue gas desulfurization and other environmental protection fields.
Although China's lime industry has made some explorations in its development in recent years, it has also achieved certain practical results. However, compared with the requirements of the state for industrial transformation and development, compared with foreign advanced indicators, there is still a gap. Therefore, while we are doing the main business of strong lime production, we must plan for the development of multi-industry. It is an important way for lime production enterprises to achieve transformation and upgrading under the new normal, and it is also a long-term and arduous strategic task faced by lime production enterprises. . Enterprises must firmly grasp the strategic opportunities of the “One Belt, One Road” initiative, give full play to the advantages of regional energy resources, learn from and draw on advanced concepts, successful experiences and mature technologies, and strive to build a circular economy industrial chain in the lime industry and accelerate the promotion of various industries. The development of low carbon efficient coupling. It is necessary to focus on creating industrial clusters for the transformation of green materials and energy resources, and make new and greater contributions to the transformation of China's lime industry and regional economic development.
Developmental favorable factors
High-quality limestone resources are the “Dinghai Shenzhen” of the future lime industry. At present, the prices of high-quality high-calcium limestone resources vary greatly from place to place, but the non-renewable and non-renewable resources and the dependence of the advantages and disadvantages of lime products on resources determine the high-quality high-calcium in the future. Limestone resources are “very expensive”, and many areas, especially underdeveloped areas, have low exploration of limestone resources, and their reserves and quality are not accurate. The development strategy of lime industry must maintain high-quality resources. Exploration or all of calcium limestone resources can create better opportunities for future lime industry development.
