Iron ore tailings complete process

Iron ore tailings complete process

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
