Hubei Huangmailing Phosphochemical Co., Ltd. was established in 1992. Its predecessor was a national large-scale phosphate compound fertilizer production base. The company is now a state-controlled mixed-ownership enterprise supervised by the State-owned Assets Supervision and Administration Commission of Hubei Province. Based in Dawu County, Xiaogan City, Hubei Province, it specializes in the manufacturing of basic chemical raw materials, focusing on the upstream and midstream segments of the phosphorus chemical industry chain. Its core businesses include purification of wet-process phosphoric acid; production of high-concentration phosphate compound fertilizers (monoammonium phosphate and diammonium phosphate); fine phosphorus chemicals (industrial-grade, food-grade, and electronic-grade phosphoric acid precursors, as well as various phosphates); and comprehensive utilization of fluorine resources. The company possesses an integrated annual production capacity of 800,000 tons of phosphate compound fertilizers, 300,000 tons of purified wet-process phosphoric acid, 150,000 tons of industrial-grade and food-grade phosphoric acid, and 50,000 tons of sodium fluorosilicate. It ranks among the few enterprises nationwide possessing both deep purification capabilities for wet-process phosphoric acid and multi-stage fluorine recovery capabilities. Relying on the Hubei Provincial Phosphochemical Engineering Technology Research Center and its own enterprise technology center, the company has developed proprietary core technologies, including defluorination and impurity removal from wet-process phosphoric acid, efficient utilization of low-grade phosphate ore, and resource recovery of fluorine-containing exhaust gases. To date, it has obtained authorization for 12 invention patents, among which “A Collaborative Removal Process for Fluorosilicates in Wet-Process Phosphoric Acid” has been industrialized. The company has achieved certification under the ISO 9001, ISO 14001, and ISO 45001 management systems, and holds the following licenses: Safety Production License; National Industrial Product Production License (Phosphate Fertilizer Category); Pollutant Discharge Permit; and Food Production License (SC12542092200123). Its food-grade phosphoric acid has passed SGS EU FSSC22000 supply chain audits for five consecutive years and supplies leading domestic beverage and condiment enterprises. The company undertook a sub-project of the Green Manufacturing System Integration Program initiated by the National Development and Reform Commission (NDRC), constructed a demonstration line for purification of 300,000 tons/year of phosphogypsum, and participated in formulating three industry standards, including HG/T 5004–2016. Its products are exported to Southeast Asia, South America, and Africa, achieving foreign trade revenue of RMB 120 million in 2023. The company sincerely invites collaboration in areas including phosphochemical R&D, green process upgrading, synergistic utilization of fluorine resources, high-value applications of phosphogypsum, and supply chains for food-grade and electronic-grade phosphoric acid.
