Embodiment 1
[0035] Containing vanadium ore A, its composition is as follows (weight ratio): V 2 o 5 1.2%, SiO 2 76.3%, Al 2 o 3 6.7%, Fe 2 o 3 3.2%, FeO 2.6%, CaO 0.8%, K 1.0%, Na 0.6%, P 2 o 5 0.1%, other 7.5%.
[0036] The vanadium-containing ore A is crushed and wet-ground to 60-80 meshes, 120 kg (dry weight) is added to the standby filtrate 2 returned from the next stage, heated to 90-100° C., reacted for 3.5 hours, and filtered to obtain filtrate 3 and Filter cake 1; filter cake 1 is mixed with standby filtrate 1, heated to 95-100°C, reacted for 2 hours, filtered to obtain standby filtrate 2 and filter cake 2, standby filtrate 2 is used to react with raw ore, filter cake 2 and 6.8 kg Phosphoric acid, 42 kg of sulfuric acid and 100 kg of water were mixed, stirred and reacted at 100°C for 1 hour, filtered to obtain standby filtrate 1 and filter cake 3, filter cake 3 was washed as cement mixture, and standby filtrate 1 was returned to leach filter cake 2 .
