The primary sources of metal iron are magnetite and hematite. After years of mining, high-quality iron ore resources are gradually depleted [9,10]. To improve the self-sufficiency rate of iron ore, comprehensive utilization of lean ore and refractory limonite resources will be a significant development direction of the upstream iron ore industry.

The global demand for iron ore with high iron contents to supply the steel industry is associated, in most countries, with the generation of tailings from mineral processing. The chemical compositions of iron ore tailings (basically Fe 2 O 3 and SiO 2 ) make them an excellent candidate as a catalyst for advanced oxidation processes (AOPs ...

1. Iron ore crushing process: In the iron ore crushing process, the feeder, first crushing, secondary crushing, screening, fine crushing and dry selection are generally used. For the sake of economy, generally the finer the ore particle size entering the dry separator, the higher the proportion of iron-bearing ore that is dry selected.
