Abstract: The characteristics of vanadium-titanium magnetite resources and the existing problems during the rapid development of vanadium titanium industry were investigated in the paper.The large quantities of gangue,tail sand,iron and steel slag have been produced by mining,ore dressing and iron making processing since 1970s.The importance,the environmental impact and the science and technique problems of multipurpose use of these industrial solid wastes as second resources were discussed in detail.Suggestions were proposed in the paper that the science sustainable development of vanadium titanium industries would be realized by reformation of traditional industries,further promotion advanced vanadium titanium materials industries such as vanadate rare earth phosphors in Panzhihua.
