Recently, the National Development and Reform Commission concluded after researching the Yichang Phosphorus chemical industry that the Yichang Phosphorus chemical industry has gradually embarked on the track of scale, integration, and scientific development. This is the result of Yichang City's persisting in its phosphate rock rectification and its own innovation.
Before 2004, the Yichang phosphate mining industry generally suffered from unlicensed exploitation of phosphate rock resources, indiscriminate mining, and mining and abandoning poverty, which caused serious waste of resources and severely constrained sustainable development. Since 2004, Yichang City has faced the problem and has carried out phosphate rock rectification work. The city has prepared a variety of plans from the comprehensive utilization of phosphate ore, phosphating industrial parks to "one mine and one well" mining, and used plans to transform the way of development and utilization of phosphate resources, and promoted full-scale mining, and all ore of low-grade grade ore was selected and synthesized. use. The implementation of the quasi-delivery order system controls the total amount of mining and the connection between production and sales, allowing mining companies to directly supply phosphate to chemical enterprises.
Through reorganization, the number of mining sites for phosphate rock has been reduced from 114 to 69. 28 mining companies in the national planning mining area were closed. Last year, the city exploited 6.5 million tons of phosphate ore, and three phosphate rock producing counties (regions) imposed a sales tax of 427 million yuan on phosphate rock, which was 3.27 times more than that before 2004.
At the same time, Yichang City vigorously carried out independent innovation work, and a number of domestic and foreign technical problems were solved here. The world’s first 30,000-ton kiln-phosphorus acid plant, first pioneered by Hubei Sanxin Phosphoric Acid Co., Ltd., passed an expert appraisal in Yichang a few days ago, fundamentally solving the problem of the utilization of low-grade phosphate rock, and achieving phosphoric acid processing without waste slag, waste gas, and wastewater discharge. . Hubei Yihua Group invested 1.2 billion yuan to build an annual output of 1 million tons of diammonium phosphate project put into operation, to solve the low-grade phosphate rock can not produce diammonium phosphate problems.
