Embodiment 1
[0020] Mix 100 parts of 1# vanadium-titanium-iron concentrate with 40 parts of sodium carbonate and 20 parts of anthracite, and keep it in a muffle furnace with a firing temperature of 1200 ° C for 3 hours to obtain vanadium-containing pig iron and vanadium-rich titanium slag; vanadium-rich The titanium slag is crushed, finely ground, leached for 2 hours at a liquid-solid ratio of 2:1, and 30°C, and then filtered to obtain a vanadium-containing solution and titanium-rich material. Among them, the chemical composition content of the vanadium-titanium iron concentrate is shown in Table 1, and the separation results of the obtained vanadium-containing pig iron, vanadium-containing solution and titanium-rich material are shown in Table 2. The iron grade in the obtained vanadium-containing pig iron is 97.62%, the recovery rate reaches 99.40%, and the vanadium-containing solution V 2 o 5 3.2g / L, vanadium recovery rate 70.46%, rich titanium material TiO 2 The grade is 35.67%, the ...

[0022] Mix 100 parts of 2# vanadium-titanium iron concentrate with 60 parts of sodium bicarbonate and 30 parts of coke, and keep it in a muffle furnace with a firing temperature of 1100 ° C for 4 hours to obtain vanadium-containing pig iron and vanadium-rich titanium slag; The vanadium-titanium slag is crushed, finely ground, leached for 4 hours at a liquid-solid ratio of 1:1, and 80°C, and then filtered to obtain a vanadium-containing solution and titanium-rich material. Among them, the chemical composition content of the vanadium-titanium iron concentrate is shown in Table 1, and the separation results of the obtained vanadium-containing pig iron, vanadium-containing solution and titanium-rich material are shown in Table 2. The iron grade in the obtained vanadium-containing pig iron is 95.38%, the recovery rate reaches 98.71%, and the vanadium-containing solution V 2 o 5 5.2g / L, vanadium recovery rate 90.50%, rich titanium material TiO 2 The grade is 42.67%, the titanium ...
Embodiment 3
[0024] Mix 100 parts of 3# vanadium-titanium-iron concentrate with 70 parts of sodium sulfate and 40 parts of bituminous coal, and keep it in a muffle furnace with a firing temperature of 1300 ° C for 0.5 h to obtain vanadium-containing pig iron and vanadium-rich titanium slag; The vanadium-titanium slag is crushed, finely ground, leached for 0.5h at a liquid-solid ratio of 4:1, and 100°C, and then filtered to obtain a vanadium-containing solution and titanium-rich material. Among them, the chemical composition content of the vanadium-titanium iron concentrate is shown in Table 1, and the separation results of the obtained vanadium-containing pig iron, vanadium-containing solution and titanium-rich material are shown in Table 2. The iron grade in the obtained vanadium-containing pig iron is 96.54%, the recovery rate reaches 99.10%, and the vanadium-containing solution V 2 o 5 4.5g / L, vanadium recovery rate 88.56%, rich titanium material TiO 2 The grade is 39.52%, the titani...
