C. b, carrying out solid-liquid separation on the leached slurry obtained in the step B to obtain an acidic vanadium solution;
D. c, dividing the acid vanadium liquid obtained in the step C into two parts, namely acid vanadium liquid a and acid vanadium liquid b, and returning the acid vanadium liquid a to the step A to circularly leach calcified vanadium extraction tailings;
E. and the acid vanadium solution b and the calcification vanadium extraction reuse water are jointly used for washing residues obtained by solid-liquid separation after acid leaching of the calcification clinker, the washing solution is used as a leaching agent for acid leaching of the calcification clinker to obtain calcification vanadium extraction tailings and qualified solution, and the qualified solution is subjected to vanadium precipitation and calcination to obtain vanadium oxide.
In the invention, the acidic low-concentration vanadium solution is obtained by further leaching calcified vanadium extraction tailings by using sulfuric acid and contains V2O51-10 g/L, Mn 5-12 g/L, P0.03-0.40 g/L, Fe 0.1-1.5 g/L, and pH 0.5-2.2; compared with vanadium liquid (V) in the calcium salt vanadium extraction process2O530-60 g/L and pH of 2.5-3.5), the concentration of TV and the pH are lower, and the method is difficult to be used for directly precipitating to obtain a vanadium product.
In the step A of the invention, the water is calcified vanadium extraction reuse water or clear water. The calcified vanadium extraction reuse water is known to those skilled in the art, and refers to water which can be recycled after the precipitated vanadium wastewater of the calcified vanadium extraction process is neutralized by lime or is subjected to electrolysis treatment, so the calcified vanadium extraction reuse water is preferred.
In the method, the acidic low-concentration vanadium liquid is circulated in the whole calcification vanadium extraction process, and water balance needs to be adjusted based on the consideration of the whole calcification vanadium extraction process, so the acidic low-concentration vanadium liquid is mixed with water.

In the step B of the method, the acid vanadium liquid with a certain volume can be obtained by controlling the dosage ratio of the leaching agent to the calcified vanadium extraction tailings; in the step D, the volume ratio is 10: 90-90: 10, the acidic vanadium solution is divided into a part a and a part b, so that the problem that the leaching rate of vanadium is influenced due to the change of acid leaching process parameters caused by the overlarge pH change of the whole circulation system is avoided; preferably, the volume ratio is 50: and 50, dividing the acidic vanadium solution into a part and a part b.
In the step E of the method, the clinker leaching is the same as that of the prior art, namely the clinker quality is fixed during the clinker leaching, namely the washing water quantity required by residue washing is determined, and the recycling water quantity for calcification vanadium extraction is determined when the quantity of the acid vanadium liquid b is determined. Generally speaking, in the step E, the mass liquid-solid ratio of the total volume of the acidic vanadium solution b and the calcification vanadium extraction reuse water to the residue is 2-3: 1.
in the method, the acidic vanadium liquid obtained in the step C can be recycled, the qualified liquid obtained in the step E can be treated to obtain calcified vanadium extraction reuse water which can also be recycled, water circulation is basically realized, no wastewater is generated in the whole vanadium extraction process, the recovery and utilization of the acidic low-concentration vanadium liquid and the calcified vanadium extraction tailings are realized, the resource waste is reduced, the process is simple to implement, and the production cost is greatly reduced.
