Embodiment 1 5
[0024] Embodiments one to five are specifically implemented in the following manner:
[0025] a. Ball milling: the vanadium-containing tailings clinker after sodium roasting is subjected to wet ball milling to obtain a mixture of vanadium-containing tailings clinker and water, and the wet ball mill controls 70% to 90% of the vanadium-containing tailings clinker particle size to pass through a 120 mesh sieve;
[0026] b. The mixture obtained in step a is vacuum filtered to obtain a solution and a waste residue.
[0027] The data obtained in the above manner are shown in Table 1.
[0028] Table 1
[0029]
[0030] According to the prior art, the comparative data obtained by washing and soaking the vanadium-containing tailings clinker with tank trucks and vacuum filtration are shown in Table 2.
[0031] Table 2
[0032]
[0033] Contrast table 1 and table 2 data and can find that the present invention compares the soluble vanadium content in moisture in the obtained spoi...
