The iron and steel industry is a key pillar of both the Chinese and global economies. Steel production relies heavily on iron ore, yet China, a leading steel producer, faces challenges with its domestic iron ore due to low grade, fine particle size, and high impurities [1], [2].This results in low resource utilization and a heavy reliance on imports.
