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.

Iron ore beneficiation is the process of improving the quality of iron ore by removing impurities and increasing its iron content. It is necessary to reduce alumina and silica in the feed. The process improves the chemical, physical, and metallurgical characteristics of the ore to make it a more desirable feed for iron-making furnaces.
