Study on flotation experiment of a kind of ilmenite from Panzhihua

According to the properties of magnetic ilmenite concentrate from a concentration plant in Panzhihua,a series of flotation experiments are carried out with reagent system of H2SO4-Na2SiO3-MOS for high intensity magnetic concentrate containing 22.09% of TiO2.The best flotation conditions are determined through experiments in various flotation conditions,and after comparing the open-circuit flotation experiment with the closed-circuit flotation experiment,experimental indexes such as the grade of titanium concentrate being 47.81% and the titanium recovery rate being 80.36% are obtained.Through comparing the ilmenite recovery rate obtained from lab with the one from field,the excellent experimental results are obtained.
