Carbon-coated sodium vanadium titanium fluorophosphate composite material and preparation and application thereof in sodium electricity

[0086] Example 1

[0087] This example uses a vanadium-titanium-titanium-titanium magnetite in Panzhihua, a 1.25 kg of vanadium-titanium-titanium magnetite, 0.1 kg of anhydrous sodium sulfate and 0.05 kg of organic binder (synthetic rubber; specifically terminal hydroxyl polybutiene) Polymer) After mixing into a 12 mm gabr, the ball is placed at a muffle furnace (air) for 45 minutes at 1100 ° C, and then removed from the cooler to 120 ° C. The bolt-baked ball was leached with 1.5L hot water, separated from the filter residue and filtrate, and the leaching solution was used to extract the production of vanadium. Crushed the filter residue to -250 specide from 75%, 0.2 kg of anthracite (leaching residue, the mass ratio of smokeless coal) added to the filter residue, mix uniform, and the group shifted into the bottom furnace (air) reduction 45 min Get high titanium slag and Zhuzhu steel. Further separation by the magnetic selection, high titanium residue is made of titanium sulfuric aci

[0089] This example uses a vanadium-titanium-titanium-titanium magnetite in Panzhihua, a 1.25 kg of vanadium-titanium-titanium magnetite, 0.1 kg of anhydrous sodium sulfate and 0.05 kg of organic binder (synthetic rubber; specifically terminal hydroxyl polybutiene) The polymer) is mixed into a 12 mm gantle, and the ball is placed at a muffle furnace (air) at 1400 ° C for 45 minutes, and after cooling to 120 ° C by the cooler. The bolt-baked ball was leached with 1.5L hot water, separated from the filter residue and filtrate, and the leaching solution was used to extract the production of vanadium. Crushed the filter residue to -250 specide from 75%, 0.2 kg of anthracite (leaching residue, the mass ratio of smokeless coal) added to the filter residue, mix uniform, and the group shifted into the bottom furnace (air) reduction 45 min Get high titanium slag and Zhuzhu steel. Further separation by the magnetic selection, high titanium residue is made of titanium sulfuri

[0091] This example uses a vanadium-titanium-titanium-titanium magnetite in Panzhihua, a 1.25 kg of vanadium-titanium-titanium magnetite, 0.1 kg of anhydrous sodium sulfate and 0.05 kg of organic binder (synthetic rubber; specifically terminal hydroxyl polybutiene) The polymer) is mixed into a 12 mm agglomerate, and the ball is placed at a muffle furnace (air) for 45 minutes at 1250 ° C, and after cooling it to 120 ° C by the cooler. The bolt-baked ball was leached with 1.5L hot water, separated from the filter residue and filtrate, and the leaching solution was used to extract the production of vanadium. Crushed the filter residue to -250 specide from 75%, 0.2 kg of anthracite (leaching residue, the mass ratio of smokeless coal), added to the filter residue, mix uniform and uniformly transferred into the bottom furnace at 1150 ° C (air) reduction 45min Get high titanium slag and Zhuzhu steel. Further separation by the magnetic selection, high titanium residue is m
