Hubei Dayukou Chemical Co., Ltd. is a large state-owned enterprise registered and established in August 2005 on the basis of the resumption of the original Dayukou mineral fertilizer combined project. With the reform and reorganization of the enterprise, the company became the holding company of China National Offshore Oil & Chemical Co., Ltd. in March 2009, with a registered capital of 1.08 billion yuan, of which: China National Offshore Oil & Chemical Co., Ltd. held a shareholding ratio of 83.97%, and the Hubei Provincial State-owned Assets Supervision and Administration Commission held a shareholding of 83.97%. The ratio is 16.03. The company currently has a land area of ??7,256 acres, total assets of 1.469 billion yuan, and a total of 1,442 employees.
The company integrates phosphate ore mining and fertilizer production. It owns two mines, Dayukou and Wangji, with more than 160 million tons of phosphate rock resource reserves. The production scale is 1.5 million tons per year of mining. 1.5 million tons/year of mineral processing, 600,000 tons/year of sulfuric acid, 200,000 tons/year of phosphoric acid, 150,000 tons/year of monoammonium phosphate, 350,000 tons/year of diammonium phosphate (or 500,000 tons/year of high-concentration compound fertilizer) . The company's main devices and equipment are imported from Europe, the United States and other countries. The self-developed medium and low-grade colloidal phosphate ore beneficiation technology is at the leading level in the industry. The compound fertilizer device co-production of ammonium phosphate technology has been selected into the twelfth batch of new enterprise records issued by the China Enterprise Association. , applied for two patents and passed the review of the National Patent Office. The "Sakofu" brand diammonium phosphate products produced by the company are of excellent quality and sell well in domestic and foreign markets.
According to China Overseas Chemical Company’s plan to build a Hubei phosphate compound fertilizer base, the Dayukou Company’s production expansion project has been approved for implementation in 2009, with a total investment of approximately 2 billion yuan. It is planned to build a new sulfuric acid plant of 800,000 tons/year, Chemical plants such as phosphoric acid 200,000 tons/year and diammonium phosphate 480,000 tons/year, mining technology transformation reaching 2.3 million tons/year, and mineral processing technology transformation reaching 2.7 million tons/year. After the project is completed, Dayukou Company will have an annual production capacity of 1 million tons of high-concentration phosphate compound fertilizers and can achieve annual sales revenue of 3 billion yuan, ranking among the large domestic phosphate compound fertilizer production bases. Dayukou is located in Huji Town, Zhongxiang City. This area covers hundreds of miles and is my country's main phosphate rock resource area. The local phosphate rock is characterized by low grade, many impurities but rich reserves. In 1958, the state established the Jingxiang Phosphate Mine here. In 1985, the Mine Party Committee applied to the province, the Ministry of Chemical Industry, and the State Planning Commission to build a 240,000-ton ammonium phosphate device here to process the phosphate rock resources on site. In June 1991, the Hubei Jingxiang Phosphate Company's 560,000-ton heavy calcium project, a key national "Eighth Five-Year Plan" project, started construction in Dayukou, also known as the Dayukou Mine-Fertilizer Integration Project.
The project is approved by the state and uses World Bank loans. The design scale is 1.5 million tons/year phosphate ore mining and processing plant, 560,000 tons/year heavy calcium, 560,000 tons/year sulfuric acid plant, 200,000 tons /year phosphoric acid plant, 10,000 tons/year aluminum fluoride. The project introduced technology and equipment from the United States, Germany, France, Sweden and other countries. Construction started in 1991 and was completed and put into operation in 1997, with a total investment of 4.669 billion yuan. Due to various reasons such as product structure, corporate management and working capital, the project suffered a loss of 620 million yuan in 1999, causing the entire Dayukou project to completely cease production. 15,000 employees and their families lost their source of livelihood, and the project with billions of state-owned assets was on the verge of extinction. Bankruptcy. The central leaders and the National Development and Reform Commission issued important instructions: "Start work as soon as possible. The longer the delay is for problems left over from history, the heavier the burden will be and the more difficult it will be to solve."
Preliminary budget estimate for the launch of the Dayukou project The investment was 389 million yuan, which was evaluated by the project review agency of the National Development and Reform Commission as 363 million yuan. During the approval process, it was lowered to 300 million yuan for lump sum use, with a time limit of 12 months. With the authorization of China Cinda, Hubei Province, and Sinochem Construction, at the end of November 2003, the working group conducted an inventory of the assets invested by Cinda and Hubei Province in the Dayukou New Company and handed over the first batch of transferred chemical plants. , mineral processing plants and other related assets. From March to May 2004, the second batch of mining, storage and transportation facilities and other facilities were handed over. Within one year, the asset handover work was completed.
On March 8, 2005, as the boiler was ignited, each device began to be tested one after another. By April 24, the phosphorus-potassium compound fertilizer transformation project was fed materials and produced qualified products.
On November 12, 2005, Hubei Dayukou Chemical Co., Ltd. was established in accordance with the law, marking the successful launch of the Dayukou mineral fertilizer integration project and entering a new stage of development.
