Since the beginning of this year, the Hubei phosphorus chemical industry has closely followed the opinions of the province on accelerating the adjustment of the chemical fertilizer industry structure to promote transformation and upgrading, promoted the rational development and utilization of Phosphate resources, actively applied new technologies, vigorously developed circular economy, extended the phosphorus chemical industry chain, and achieved Phosphate resources integration and phosphorus chemical industry development go hand in hand with a brilliant start.
According to Huang Wenjun, director of the Hubei Provincial Phosphorus Chemical Market Management Committee, in recent years, the province has achieved remarkable results in the integration of phosphate resources. The total number of mines in the province has been reduced from 146 to 88 before the integration. The development of phosphate resources is small and scattered. The phenomenon of chaos has been significantly improved, the level of exploitation and utilization of mineral resources has been improved, and the recovery rate of phosphate rock mining in the province has increased from 60% to 80%. On November 1 this year, Yichang Liushugou Mining Co., Ltd. and Liyang Baokang Yizhihe Mining Co., Ltd. were identified by the Ministry of Land and Resources as the first batch of integrated mineral mines for the development and integration of advanced mines.
The development of Phosphorus chemicals began with the management of chaos in phosphate mining. Since this year, Hubei Province has effectively strengthened the management of exploration, exploitation, protection and utilization of phosphate resources, scientifically formulated the development of Phosphorous mineral resources, plans for the development of Phosphorus chemicals, and conducted planning environmental impact assessments. To guide the rational distribution of the phosphate fertilizer industry, vigorously promote the prospecting and development of phosphate rock resources, optimize the allocation of resources, and concentrate the phosphate mineral resources in large-scale key phosphate chemical enterprises and advantageous enterprises, effectively curb the use of wealth to abandon poverty and eliminate chaos. Mining phenomenon. At the same time, Hubei Province will increase the management of phosphate rock transportation, strictly limit the export of phosphate ore, reasonably regulate the flow of phosphate minerals, clean up and integrate existing phosphate development enterprises, and provide resources for the sustainable development of phosphorus chemical industry in the province. .
For the use of phosphate rock, Yichang City has its own hard rules: for phosphorus minerals with a grade of more than 28%, it is preferred for the production of yellow phosphorus, Ammonium Phosphate, and NPK compound fertilizers; for phosphate rock with a grade of 24% to 27%, It is mainly used for the production of ordinary phosphate fertilizers. For phosphate minerals with a grade below 24%, it is mainly used for the production of beneficiation enterprises that meet the requirements of the development plan for phosphorus chemical industry. The selected phosphate concentrates are preferentially connected with the phosphorus chemical companies.
Zhongxiang City, known as the "Central China Phosphorus City," also clearly stipulates that all mining mines without licenses shall be banned according to law; mines with a mining capacity of 100,000 tons or less must be shut down and transferred every year, and the city's production capacity is not up to the standard. 35 The domestic mineral powder company and 32 small fertilizer companies were all shut down. Up to now, there are more than 130 phosphate chemical companies in the city reduced to 68, and more than 40 mining companies have dropped to 10.
Hubei Province will give full play to the advantage of phosphate rock resources and support Yihua Group, Xingfa Group, and Xinyang Fengfei, etc., to integrate phosphate rock resources development and fertilizer production enterprises, optimize the allocation of phosphate resources, and guide the production factors to advantage. The company concentrates on the integration of phosphate mining, ore dressing, fertilizer production and fine chemical production, and builds a group of leading phosphate chemical enterprise groups in the country. In late October, the middle and low grade phosphate rock comprehensive utilization demonstration bases in Xingfa and Yihua were included in the first batch of 40 demonstration bases for comprehensive utilization of mineral resources in China. Five years later, these bases are expected to become the "leaders" of China's green mining industry.
On August 14th, Yihua Huarui Mining obtained the right to explore Cahalo Phosphorus deposit in Leibo County, Sichuan Province issued by the Department of Land and Resources of Sichuan Province, with an exploration area of ​​30.64 square kilometers and a preliminary proven geological reserve of 123 million tons with an average grade of 23.44. %, The mine is planned to build about 1.5 million tons of phosphate rock per year.
As the national phosphorous chemical industry leading enterprise, Xingfa Group, it will invest 10 billion yuan in Liyang to develop and utilize phosphate ore resources and silicon resources during the “12th Five Year Plan†period. At the same time in Xingshan, Baokang, Shennongjia, Yichang, and Yunnan and Guizhou in Hubei Province. The construction of a large-scale production base for phosphorous chemicals is expected to reach an annual production capacity of nearly one million tons. This year, these projects are going well. Xingfa Group also signed a cooperation framework agreement with Guizhou Yifu Group to cooperate in deep processing of phosphorus chemical industry and comprehensive utilization of resources.
In November, Hubei Saning Chemical Industry Co., Ltd. used a set of industrialized plants with an annual output of 10,000 tons constructed by Huazhong Normal University's wet phosphoric acid refining technology to achieve stable operation for 7 consecutive months, with a daily output of 40 to 43 tons of purified phosphoric acid. It is expected to reach more than 13,000 tons. At present, the company is designing an annual production capacity of 100,000 tons, and is striving for completion and production next year. The project mainly uses middle-low grade phosphate ore as raw material, and the industrial-grade 85% phosphoric acid produced can be completely comparable in quality to thermal process phosphoric acid. The overall energy consumption is only 50% of the thermal process and the cost is only 80% of the thermal process. . The successful application of this technology has broken the monopoly of foreign companies in the refining of wet-process phosphoric acid.
Not only that, since the beginning of this year, Hubei phosphorus chemical companies have vigorously promoted the application of new energy-saving and emission-reduction technologies, new equipment, and new technologies, and promoted resource conservation and recycling, and have made gratifying new achievements.
