The inorganic salt industry is an important basic raw material industry with 22 series and more than 1300 products. During the "11th Five-Year Plan" period, the inorganic salt industry has made considerable progress. At present, China's inorganic salt industry already has a considerable scale and foundation. It has a complete range of products and varieties, and has become the world's largest producer, exporter, and consumer of inorganic salts. In 2009, China's total output has exceeded 50 million tons and its export volume has reached 12.05 million tons.
Progress in structural adjustment During the “Eleventh Five-Year Plan†period, China’s inorganic salt products increased in size, improved in grade, and generally increased in production capacity and output. Potash achieved great development. It has built two bases in Qinghai Chaerhan and Lop Nur in Xinjiang. The production technology and single set of production facilities have reached or approached the international advanced level. The nanometer, whisker, high-purity, and surface-treated modified inorganic salt products have developed prominently, and the annual output of nano-calcium carbonate has reached hundreds of thousands of tons. Flame retardant extinguishing agents, catalysts, pharmaceutical-grade high-purity reagents and other inorganic products have a good development situation, while yellow phosphorus, sodium dichromate, chromic anhydride, sodium cyanide, sodium sulfide, and other highly polluting products with high environmental risk are associated with backward products. Accelerate the elimination, and the growth rate has dropped. Some products have seen negative growth. The scale of inorganic salt industry has been greatly increased. The degree of industry concentration has been significantly improved, the industrial production layout has been adjusted, and resource support has become more reasonable. The average production capacity of sodium dichromate companies exceeds 26,000 tons; feed phosphate production capacity is further concentrated in advantageous regions and advantageous enterprises, and Sichuan and Yunnan provinces account for more than 70% of the country's production capacity, while Longjing, Chuanheng, and Xinlong have also Occupy 60% of its production capacity; the production of barium salts has gradually shifted from Shandong and Hebei, which are far away from the raw material production base, to Guizhou and Shaanxi.
Significantly accelerated technological progress During the "Eleventh Five-Year Plan" period, the chromium salt industry developed a calcium-free roasting method and liquid phase oxidation of sodium dichromate production technology. The purification of wet-process phosphoric acid to produce industrial-grade and food-grade phosphoric acid has achieved large-scale industrial production. Carbon disulfide has developed a continuous fluidized bed coke process that reduces energy consumption by more than half compared to the traditional coke process and has become the most advanced carbon disulfide production technology in the world. The progress of industrial restructuring has been accelerated, and silicates, phosphorus chemicals, inorganic fluorides, potash fertilizers, potassium salts, chlorates, cyanides, and peroxides have been coupled with the upstream and downstream industries, which has lengthened the industrial chain and enabled the effective use of resources. Reduced pollutant emissions and increased industrial standards.
Inorganic salt companies have also combined with research institutes to develop ultra-clean high-grade products, such as electronic grade H2O2, H3PO4, HF, PH3, phosphate, etc. The conditions for the localization of semiconductors and integrated circuit support materials are basically mature.
Increased comprehensive utilization level During the "11th Five-Year Plan" period, the inorganic salt industry actively promoted cleaner production processes, enhanced comprehensive utilization of resources, eliminated high-energy-consumption, low-efficiency, heavy-polluting process technologies and equipment, and heavily polluted products such as chromium salt and cyanide. Chemicals, etc., strengthened the management of production licenses and improved access thresholds. The technology of waste heat recovery, dust removal and comprehensive utilization of the kiln exhaust gas is fast, and the promotion is large, and the effect of energy saving and emission reduction is significant. The chromium salt industry developed chromium slag instead of hydrated lime as a flux for sintering ironmaking, used as cement additives and mineralizers, made low-chromium cast iron, high-temperature fusion-produced cement co-produced chromium cast iron and potash and other ten comprehensive utilization technologies There are a number of chromium salt companies using these technologies to solve the problem of chromium residue left over from history.
Significant achievements in resource protection During the “Eleventh Five-Year Plan†period, through the implementation of strict control measures on total mining volume and export policies and measures, China has effectively protected rare and internationally dominant chemical and mineral resources such as rare earths and fluorite. In terms of rare earths, the state has successively introduced a series of measures. The situation that the prices of rare earth products are too low has been reversed, and it has won the international "right to speak." Since 2007, the state has implemented a mandatory plan for rare earth mineral products. The major rare earth production areas in Inner Mongolia, Jiangxi, Sichuan, Guangdong, and Fujian provinces have increased the order of exploitation and resource integration. From 2008 to 2010, on the basis of the original tightening policy of rare earth production directive plans to control production and reduce export quotas for rare earths, the government has gradually begun to implement a centralized purchasing and storage system for government and enterprises, and has formulated a system for admitting industry and a new environmental protection standard. And many other policy controls. With the deepening of the order of mineral resources and the adjustment of industrial structure, the prices of rare earth products have also risen year after year. The strategic resources of rare earths have been effectively protected. In terms of fluorspar, the country has continuously strengthened the control over the export of fluorspar, rectified the mining order several times, included the fluorite export in quota management, reformed the bidding system for export quotas, and included fluorite in the list of prohibited commodities for processing trade. Gradually increase the tariff rate of fluorite exports, so that China's fluorspar export volume decreased by approximately 10% year by year.
