Firstly, the phosphorus content is measured in calcified clinker, if the phosphorus content is not more than 0.06%, the phosphorus inhibitor switch is closed, namely the phosphorus inhibitor is not added into the acid leaching vanadium liquor, in practical application, the phosphorus content can be expressed by the ratio of vanadium content to phosphorus content, namely V/P, in this case, if the V/P is not more than 175, the phosphorus inhibitor switch is closed, namely the phosphorus inhibitor is not added into the acid leaching vanadium liquor. If the phosphorus content is more than 0.06%, the phosphorus inhibitor switch is turned on, namely adding the phosphorus inhibitor into the acid leaching vanadium liquid, and in practical application, the method can also be expressed as that if V/P is more than 175, the phosphorus inhibitor switch is turned on, namely adding the phosphorus inhibitor into the acid leaching vanadium liquid. Wherein the content of phosphorus is within the range of 0.06-0.10%, the content of phosphorus inhibitor is 10%, and the content of phosphorus is within the range of 0.10-0.20%, the content of phosphorus inhibitor is 20%.

If the phosphorus content is more than 0.03g/L, the phosphorus inhibitor switch is turned on, namely adding the phosphorus inhibitor into the acid leaching vanadium liquid, and in practical application, the method can also be expressed as that if V/P is more than 1050, the phosphorus inhibitor switch is turned on, namely adding the phosphorus inhibitor into the acid leaching vanadium liquid. Wherein the content of phosphorus is within the range of 0.03-0.04g/L, the content of phosphorus inhibitor is 10%, and the content of phosphorus is within the range of 0.04-0.05g/L, and the content of phosphorus inhibitor is 20%.

dooff ('turn off phosphorus inhibitor switch')
else do on ('turn on phosphorus inhibitor switch')
