(2) after slurry pH is stable, inoculating thiobacillus ferrooxidant liquid, in thiobacillus ferrooxidant liquid, the amount of thiobacillus ferrooxidant is 106~108Individual/mL, inoculum concentration is 1.0 ~ 5.0%；
(3) constant temperature leaching.
Preferably, in step of the present invention (1) described ilmenite ore pulp, the mass percent concentration of ilmenite is 17 ~ 24%.
Preferably, step of the present invention (1) described sterilization treatment is high pressure steam sterilization.
Preferably, the temperature of high pressure steam sterilization of the present invention is 120 ~ 150 DEG C, and the time is more than 20min, and pressure is 1 × 105~2.2×105Pa。
Preferably, the extraction temperature of constant temperature leaching of the present invention is 22 ~ 38 DEG C, and rotating speed is 120 ~ 180r/min.
Preferably, use sample ore of the present invention is that ilmenite comminution is more than or equal to 99% to Ore fineness for-0.074mm content.
Sample ore of the present invention is that ilmenite minal or vanadium titano-magnetite process gained ilmenite concentrate product, TiO through ore dressing2Content is more than or equal to 50%.
The principle of the present invention is: be inoculated in by thiobacillus ferrooxidant in the ilmenite ore pulp after comminution, Fe2+Owing to being fettered by the lipopolysaccharide in cell envelope, form lipopolysaccharide phospholipid ferrous iron complex in extracellular, and then provide the electron transmission of system to provide electronics for cytochrome system, promote Fe2+→Fe3+Transformation；Make reaction 4FeTiO3+O2+12H+→4H2TiO3+4Fe3++2H2O, under the catalysis of thiobacillus ferrooxidant, is carried out to the right；The method utilizes the oxidation-reduction process that microorganism own metabolism is adjoint, accelerate the dissolving of ilmenite, it is to avoid the use of the strong acid in conventional leaching method, reduces the requirement to equipment.
The invention have the benefit that
(1) equipment investment is few, and energy consumption is low, and producing cost is low；
(2) reduce the consumption of acid in production process, decrease the corrosion to equipment, improve the service life of equipment；
(3) decreasing the discharge of garbage, environmental pollution gently and is easily administered；
(4) it is that the process of ilmenite puts forward new thinking, has fabulous prospects for commercial application.
