A method for beneficiation of magnesite ore wherein the ore is subjected to calcination to decrease the bulk density of the magnesite relative to the gangue. Accordingly, after such calcination, conventional gravimetric separations can be conducted with greatly increased efficiency. When the calcination is conducted in a reducing atmosphere, initially non-magnetic gangue material is converted ...

Iron ore tailings (IOTs) are a form of solid waste produced during the beneficiation process of iron ore concentrate. In this paper, iron recovery from IOTs was studied at different points during a process involving pre-concentration followed by direct reduction and magnetic separation. Then, slag-tailing concrete composite admixtures were prepared from high-silica residues.
