Experimental Research on Comprehensive Recovery of Iron and Phosphorus from the Low Grade Vanadium -titanium Magnetite Ore

摘要

An experimental research on comprehensive recovery of iron and associated apatite from a low grade vanadiferous titanomagnetite ore with high phosphorus was carried out. The results showed that using the technological flowsheet of "low -intensity magnetic separation-flotation", not only the magnetite can be effectively separated, but the associated apatite in the mineral resources can also be satisfactorily recovered. An iron concentrate with a TFe grade of 64.81% and iron recovery of 58.04% and a high-quality phosphorus concentrate of 33.50% P_2O_5 with a yield of 92.18% is obtained.
