A study of reduction and magnetic separation of iron from

Abstract. The removal of iron as magnetite from a high iron bauxite ore was investigated by carbothermal reduction and magnetic separation. Thermodynamic calculations using HSC Chemistry 6183;1 were utilised to determine the equilibrium compositions of the reaction products as a function of temperature and carbon additions.
