In recent years, the recycling of solid waste rich in iron to obtain iron oxides has become a major research topic. For example, residues such as mill scale that is considered a waste in the steel rolling industry, can be used as raw material to synthesize pigments of red iron oxide (hematite), due to

Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.
