Recently, the land preparation work for the integrated coupling cycle project of \"phosphorus, sulfur, titanium, copper, iron, and lithium fluoride\" in Kaiyang, Guizhou, was launched, with the construction of pile foundations for the main factory building proceeding simultaneously. The establishment of the first-phase lithium iron phosphate production line with an annual capacity of 600,000 tons is scheduled to be completed by the end of 2025. This project is the first project in Guiyang worth over 10 billion yuan in 2025, with a total investment of 33.1 billion yuan. It was developed jointly by the Guiyang Municipal Government and Guizhou Phosphorus Chemical (Group) Co., Ltd., in collaboration with companies such as China National Nuclear Huayuan Titanium Dioxide and China Minmetals Resources Group. The aim is to create an innovative model for the integrated development of new energy materials and traditional chemical industries through the consolidation of resources across the entire industry chain. The project includes a wide range of construction activities: 1.4 million tons of ferrous sulfate heptahydrate, along with 400,000 tons of titanium dioxide, 600,000 tons of iron phosphate, 600,000 tons of lithium iron phosphate, 150,000 tons of lithium carbonate, 10,000 tons of lithium fluoride, 20,000 tons of lithium hexafluorophosphate; copper smelting operations, the production of sulfuric acid from phosphogypsum, cogeneration projects, and various auxiliary infrastructure projects. This setup enables the creation of a complete chain that spans resource extraction, deep processing, and the production of end products. Technical highlights of the project: Optimal utilization of by-products. In terms of technical details, the most groundbreaking aspect of this project is the optimal utilization of by-products. After phosphorus ore is processed to produce iron phosphate, it is combined with ferrous sulfate, a by-product of titanium dioxide, to manufacture lithium iron phosphate. Meanwhile, the phosphogypsum waste generated in traditional processes is decomposed to produce sulfuric acid, resulting in a reduction of 2 million tons in solid waste emissions per year. This model of \"converting industrial waste into a resource for industry\" has reduced the carbon emission intensity of the project by 40% compared to traditional processes, making it a textbook example of green transformation in the phosphorus chemicals industry. \"Chemical coupling\" in the industrial chain: When a production line for 400,000 tons of titanium dioxide operates alongside a facility for producing 1.4 million tons of ferrous sulfate heptahydrate, this not only alleviates the profit concerns of titanium dioxide manufacturers (China National Titanium White’s gross margin dropped to 18% in 2023 due to industry overcapacity), but it also results in cost savings of 2,000 yuan per ton for lithium iron phosphate, as it reduces the cost of iron sources. This cross-industry technological integration has placed Guizhou in a strategic position where the lithium battery materials and titanium dioxide industries can develop together. Significance of the project for Guizhou’s new energy industry: This project targets the weaknesses in Guizhou’s new energy industry, focusing on overcoming the supply constraints related to key resources such as lithium, iron, and copper. For example, a production capacity of 600,000 tons of lithium iron phosphate can meet 15% of the national demand for cathode materials in lithium batteries, while 10,000 tons of lithium fluoride and 20,000 tons of lithium hexafluorophosphate will help improve the electrolyte industry chain. At the same time, the entry of leading titanium dioxide manufacturers has filled the gap in this sector in Guizhou. Upon completion of the project, Guizhou will become the world’s largest production base for phosphorus-based cathode materials, accounting for over 30% of the national market share.
