The invention provides a method for preparing metal titanium. The method comprises the steps of: mixing, pressing and drying titanium oxide and a carbon reducing agent to obtain an anode material; and connecting the anode material with the electric conductive part to form an anode, taking metal or alloy as a cathode, taking alkali metal chloride fused metal and/or alkaline earth chloride fused salt as an electrolyte for electrolysis under an inert atmosphere to obtain the metal titanium powder. The electrolyte further contains TiCl2 (titanium dichloride) and TiCl3 (titanium trichloride). The method provided by the invention has the advantage of low energy consumption.
