en.Wedoany.com Reported - On April 29, China Hydrogen Union Mining Technology (Yingkou) Co., Ltd.'s annual processing of 24 million tons of iron ore using hydrogen-based mineral phase conversion technology officially passed filing and approval, becoming the world's first ten-million-ton-level industrial engineering project for this technology. The project had previously received filing approval from the Bayuquan District Development and Reform Bureau on April 24. The project adopts the internationally pioneering hydrogen-based mineral phase conversion technology, using hydrogen produced from natural gas reforming as a clean reducing agent to precisely transform traditionally difficult-to-utilize weakly magnetic iron minerals into strongly magnetic magnetite, increasing magnetic separation recovery rates by more than 15 percentage points compared to conventional processes.
The project covers a total land area of approximately 1 million square meters, with a total of 419 sets of equipment, including 8 sets of natural gas hydrogen production units, and will be constructed in two phases. Phase one will be launched first, processing 6 million tons of raw ore annually and producing 4.3716 million tons of iron concentrate per year, supported by 2 sets of natural gas hydrogen production units. Upon full operation in phase two, the project will process 18 million tons of raw ore annually, producing 13.1148 million tons of iron concentrate per year. The total annual iron concentrate output for the entire project will reach 17.4864 million tons, with an annual tailings output of 5.8248 million tons. Hydrogen Union Mining Technology (Yingkou) Co., Ltd. is registered in Yingkou City, and its parent company, Beijing Hydrogen Union High-Tech Energy Technology Co., Ltd., is a technology-oriented enterprise focused on hydrogen energy technology development.
Hydrogen-based mineral phase conversion technology is an international first, proposed and led in research and development by the team of Professor Han Yuexin from Northeastern University. This technology features high production capacity, environmental friendliness with no pollution, low production costs, and a high degree of automation. Preliminary estimates suggest it can revitalize over several hundred million tons of iron ore resources both domestically and internationally. Previously, multiple engineering demonstration projects using this technology have been established in locations such as Jinzhou, Liaoning, and Changjiang, Hainan, with capacities of 4 million tons and 2 million tons respectively. Among them, Hainan Mining's 2-million-ton project completed ignition and furnace drying in November 2023. The annual 4-million-ton hydrogen-based mineral phase conversion project of Liaoning Jinzhou Dongshi Mining is also concurrently advancing its environmental impact assessment, with a total investment of 1,138.4713 million yuan. The landing of this Yingkou project is expected to provide a new large-scale utilization pathway for China's vast reserves of low-grade, difficult-to-process iron ore, further reducing the country's dependence on foreign iron ore.
