The invention discloses an acidolysis process for titanium dioxide production, relates to the technical field of non-ferrous metal metallurgy, and solves the problem that in the reaction process and after the reaction is finished, in order to improve the reaction of acid ore, a spiral stirrer is generally adopted to stir reactants to promote the proceeding of the reaction. In the step 2, compressed air is introduced to stir a main reaction product, in the step 3, sand filter water and compressed air are introduced to stir and dissolve a cured product, and compressed air with different flows and temperatures is adopted in different steps. The stirring speed of the reaction can be changed by accurately controlling the flow speed of the introduced air, and the reaction temperature in each step can be changed and adjusted by changing the temperature of the compressed air, so that the flexibility in the whole reaction process is improved, the reaction efficiency of the whole reaction is improved, and the completen
