Guizhou’s phosphating industry is reshaping the industry landscape: including projects such as 600,000 tons of iron phosphate and 150,000 tons of lithium carbonate

Recently, Guizhou Phosphorus Chemical Group has thoroughly implemented the new development concepts, aiming to build an ecosystem for the entire new energy industry chain. By relying on the construction of the integrated circular economy project involving \"phosphorus-sulfur-titanium-copper-iron-lithium-fluorine\" in Kaiyang, Guizhou, the group focuses on integrating resources, advancing technological innovation, and fostering industrial collaboration. It strives to address the shortcomings in new energy materials and promote the development of the industry chain in a more advanced, sustainable, and integrated manner, thereby providing strong impetus for the development of the province’s modern industrial system. First, use major projects to drive the development of industrial clusters. As Guiyang’s first project worth over 10 billion yuan in 2025, the integrated phosphorus-sulfur-titanium-copper-iron-lithium-fluorine coupled cycle project was launched on April 27. This project establishes a coordinated development framework comprising four key sectors: new energy materials, sulfur-titanium smelting, metal processing, and utility services. It includes over 10 core projects, such as the production of 1.4 million tons of ferrous sulfate heptahydrate, along with 400,000 tons of titanium dioxide, 600,000 tons of lithium phosphate, and 150,000 tons of lithium carbonate. Once the project is completed, the Phosphating Group will achieve self-sufficiency in lithium, iron, and titanium resources. The excess lithium carbonate, ferrous sulfate heptahydrate, and other raw materials can be supplied to other new energy enterprises within the province, helping Guizhou Province overcome the situation of having to rely on selling raw materials derived from phosphate mines, and addressing the shortages of resources such as lithium, iron, and copper in the new energy industry. Second, activate the potential value of resources through a circular economy model. Through seven resource recycling systems of \"phosphorus-sulfur-titanium-copper-iron-lithium-fluorine\", the project extends the value chain of phosphate rock to six high-end sectors, including new energy batteries, fluorine chemicals, and titanium dioxide. On the one hand, this project processes phosphate rock to produce iron phosphate, which is then combined with ferrous sulfate – a byproduct of titanium dioxide production – to manufacture lithium iron phosphate. It also includes a process for decomposing phosphogypsum to produce sulfuric acid; as a result, 2 million tons of solid waste are reduced annually, and the carbon emission intensity is 40% lower compared to traditional processes ； On the other hand, the project’s 400,000-ton titanium dioxide production line operates in tandem with a 1.4-million-ton integrated facility for producing ferrous sulfate heptahydrate. Through “chemical coupling,” this setup reduces the cost of iron sources used in lithium iron phosphate production by 2,000 yuan per ton. This not only alleviates the profitability pressures within the titanium dioxide industry but also fosters cross-industry synergies. Consequently, it significantly enhances the Group’s ability to withstand risks within its new energy industry chain. In doing so, it contributes phosphorus-based expertise to helping Guizhou gain a strategic edge in the coordinated development of both lithium battery materials and titanium dioxide industries.
