1. Introduction. China is a country lacking in highquality iron ore, even though it contributes 45% of its output to the world's steel production [1].Most of China's iron ore is a complex ore with a low iron grade and is difficult to beneficiate [2].Therefore, China has sourced more than 85% of its iron ore from abroad and imported nearly 1 billion tons of iron ore annually since 2015 [3].

Magnetization roasting followed by magnetic separation is considered an effective method for recovering iron minerals. As hematite and magnetite are the main concomitant constituents in iron ores, the separation index after the magnetization roasting will be more optimized than with only hematite. In this research, the mechanism of the original magnetite improving iron ore reduction during the ...
