On September 1, 2026, the world’s largest magnetical roasting project for difficult-to-process iron ore was officially completed and accepted in Anshan City, Liaoning Province. This project was developed by the team led by Zhu Qingshan from the Institute of Process Engineering of the Chinese Academy of Sciences, and was jointly constructed with Ansteel Mining. It has the capacity to process 5.56 million tons of ore per year. The project successfully converted iron tailings with only 11% iron content into iron concentrate products with a grade exceeding 65%. The project includes three production lines, and operational data shows that the mineral phase conversion rate reached 98%, while the overall energy consumption was 35% lower than similar technologies, and all indicators exceeded the design expectations. Currently, this project has been included in the first list of green and low-carbon advanced technology demonstration projects by the National Development and Reform Commission, indicating that China’s long-idle low-grade difficult-to-process iron ore is expected to be utilized on a large scale.
