Iron ore tailing is a major solid waste requiring advanced recycling methods because ore tailing powder is polluting air and water resources. For instance, about 300 million tons of tailings are disposed yearly in 1229 iron ore tailings dams in the Hebei province in China. Iron ore tailings can be recycled as functional materials because these tailings are …
