According to Sinochem New Network, on April 27, news came from Panzhihua Quanrui Industrial Co., Ltd. that the research team led by Pu Zhonghua at the company, in collaboration with relevant domestic institutions, utilized a high-purity ferrous chloride solution—produced as a by-product in Quanrui Industrial’s non-extraction hydrochloric acid-based titanium dioxide production process—as the sole iron source. Applying a multi-element material metallurgy approach, they successfully conducted an industrial-scale experiment on “the liquid-phase preparation of lithium manganese iron phosphate cathode materials using ferrous chloride solution,” ultimately producing lithium manganese iron phosphate (LMFP) cathode materials with excellent performance. According to Pu Zhonghua, the key technical advantages of this experimental project are full circulation and zero emissions; chloride ions and hydrochloric acid are fully reused, while all iron elements are incorporated into the cathode material, with no waste discharged outside. It has been achieved to convert ferrous chloride, a by-product of titanium dioxide production, into an iron source for new energy cathode materials. The chloride ions are recycled back into the titanium dioxide production process in the form of hydrochloric acid, thus establishing a complete closed loop. This process enables the conversion of ilmenite into titanium dioxide via the hydrochloric acid method, followed by the production of ferrous chloride, and ultimately yielding qualified lithium manganese iron phosphate products. This process technology possesses independent intellectual property rights; there is no waste liquid or solid waste generated throughout the process, which significantly reduces the cost of iron sources. It provides a replicable model for the green transformation of the titanium dioxide industry. Test data from a third-party authoritative testing laboratory show that in this acidic system, the key iron source (recrystallized ferrous chloride solution) contains a high concentration of iron – around 160 g/L – with low levels of impurities. Manganese is present as a natural by-product, and all other impurities are below the specified limits. The test results indicate that this substance meets the requirements for an iron source in lithium iron manganese phosphate ； The lithium iron manganese phosphate cathode material (model MX10) has low levels of impurities; the contents of sodium, potassium, boron, chromium, zinc, nickel, sulfur, etc., are all relatively low. The titanium content is slightly higher due to doping. Its electrochemical properties are as follows: operating voltage range of 2.8–4.3V; initial discharge specific capacity at 0.1C is >150 mAh/g, with an efficiency exceeding 92%; initial discharge specific capacity at 1C is >140 mAh/g. The rate capability (1C/0.1C) exceeds 92%. The material exhibits a standard olivine crystal structure. In conclusion, it meets the requirements for battery-grade products. Pu Zhonghua pointed out that the success of this experiment signifies that Quanrui Industry’s proprietary non-extraction hydrochloric acid process for titanium dioxide production has achieved a strategic transition from “solely producing titanium dioxide” to “co-producing titanium and lithium” ； The process technology offers significant value in terms of circular economy; chloride ions are fully recovered in the form of hydrochloric acid and returned to the titanium dioxide production process, resulting in zero loss of this medium ； The iron from ferrous chloride is incorporated into lithium manganese iron phosphate, with no liquid or solid waste discharged. This results in significantly lower product costs and enhanced competitive advantages. In the titanium dioxide production system using hydrochloric acid without an extraction process, multi-element materials are employed to produce high-purity ferrous chloride on a combined basis; this replaces high-purity ferrous sulfate, electronic-grade iron oxide, and ferrous oxalate as the iron source. Such an approach enables the supply of large quantities of a stable iron source for lithium manganese iron phosphate, allowing the cost of the iron source used in this material to be reduced by more than 40%. It is understood that the Panxi region is rich in vanadium-titanium magnetite resources. Under traditional processes, only titanium and vanadium are recovered, while vast amounts of iron resources are left accumulated as low-value by-products. Quanrui Industry’s new integrated closed-loop process technology has opened up a completely new industrial chain pathway for vanadium-titanium magnetite in the Panxi region: \"ore → titanium dioxide → ferrous chloride → lithium manganese iron phosphate\". This approach enables the synergistic and high-value utilization of multiple elements such as iron, titanium, chlorine, lithium, and manganese, thus providing a new route for the high-value exploitation of vanadium-titanium magnetite in that area.
