H2The excellent gas inductive material of S, Fenton-like catalysts, photocatalysis degradation organic contaminant and smelting contain vanadium about
40% vanadium iron primary raw material etc..Currently, related preparation FeVO4Report it is also fewer, mainly have high-temperature solid phase reaction method,
The synthetic methods such as hydro-thermal method.
It is tailings of the pneumatic steelmaking vanadium slag after extracting for several times containing vanadium tailing soil, is a kind of intractable containing vanadium mineral.Tail
It is still very high containing vanadium in slag, in terms of the utilization of resources and environmental protection two, it is significant to recycle vanadium therein.
The corporate boss of production vanadium pentoxide will be based on sodium roasting vanadium-extracting, since this is high containing composition contained by vanadium tailing soil at present
The low vanadium of calcium so being difficult to directly use in sodium roasting vanadium-extracting enterprise containing vanadium tailing soil, therefore is used as metallurgical raw material, cement, road mostly
The construction materials such as sill will cause prodigious vanadium to waste, and vanadium tool has been widely used, and is a kind of gold that economic value is high
Belong to.
Existing calcification vanadium extraction is although feasible using technology containing vanadium tailing soil, but due to needing ball processed roasting, then acidleach, then
It will will appear production cost height using resin adsorption or the means vanadium extraction for extracting class, energy consumption is high, pollutes environment, once market
The landing of vanadium valence will be difficult to continue to produce, and utilize and have difficulties containing vanadium tailing soil.
The present invention has studied a kind of utilize and prepares ferric vandate method containing vanadium tailing soil using on the basis of containing vanadium tailing soil.
