The paper employed reduction sodium-modified roasting,grinding and leaching,and magnetic separation processes to recover vanadium and iron from vanadium titanium magnetite iron concentrate,and investigated the factors that influence the recovery of vanadium and  iron  in the roasting process,such as roasting temperature,roasting time,reducing agent dosage and sodium-modified agent dosage.Ammonium metavanadate products and crude iron products containing over 80 % iron were obtained,and the good technical indexes of iron recovery rate 92.82 % and vanadium recovery rate 84.61 % were obtained.
