芬兰劳塔é²group's Aotanmaji ore containing 40% of mineral magnet containing V 0.25% ~ 0.3%. Vanadium is present in the titanium magnetite crystal lattice. The ore is first magnetically removed to remove the gangue, and then finely ground to 0.1 ~ 0.2mm, wet magnetic separation to obtain vanadium magnetite concentrate, the composition is as follows:
Composition V Fe TiO 2 SiO 2
% 0.65 69.5 1.8 0.5
The process is characterized by the use of pellets in the shaft furnace for sodium oxide roasting. A pellet of 10 to 12 mm was prepared by adding 3% to 6% of soda ash, and the furnace was kept at 1200 ° C for about 11 hours. Cooled to 600 ~ 700 ° C out of the furnace. Dip in water for 36h. The vanadium leaching rate is greater than 95%. Al 2 (SO 4 ) 3 was added to remove silicon, and the supernatant was added with ammonium sulfate to precipitate ammonium polyvanadate. The pellet after leaching is used as a raw material for iron making.
Musta Walla was the new base discovered by the company in 1962 and was completed and put into production in 1976. The ore contains Fe 17% and V 0.2%. The process is basically similar to that of Ortamaki. The total recovery of vanadium is 77%. The vanadium precipitation rate is 99.8%, with an annual output of V 2 O 5 3kt. The finished ingredients are as follows:
Finished product | V 2 O 5 | V 2 O 4 | Fe 2 O 3 | SiO 2 | Na 2 O | K 2 O | NH 3 | H 2 O |
Ammonium vanadate /% | 90 | 0.6 | 0.02 | 0.1 | 0.1 | 0.1 | 5.6 | 3.2 |
Foil /% | 92 | 6.0 | 0.05 | 0.15 | 0.1 | 0.1 |
