The invention discloses a method for preparing ferrotitanium with titanic iron ore, comprising the following steps: 1, preparing titanic iron ore electrode by crushing, evenly mixing, press-forming and high-temperature sintering the titanic iron ore raw material in the selected ore, of which the main impurity elements are P, S, Mg, Al, Ca, O and Si; 2, carrying out fused salt electrolysis by taking titanic iron ore electrode as the cathode, and graphite rod as the anode under the protection of argon to obtain the primary titanic iron ore product in which the main impurity elements are S, P and Si; and 3, vacuum melting the washed and dried primary titanic iron ore product in a vacuum furnace to remove the impurity elements of S, P and Si contained in the primary product so as to obtain the ferrotitanium. The method has simple preparing steps and convenient operation and low cost, can greatly reduce the energy consumption and environment pollution in metallurgy process and can effectively avoid waste of mineral resources.
