Description

Miscellaneous ore-dressing technique drops in apatite vanadium titano-magnetite
Technical field
The invention belongs to technical field of beneficiation, drop miscellaneous ore-dressing technique more particularly to a kind of apatite vanadium titano-magnetite.
Background technique
Titanium has the advantages of steel (intensity high) and aluminium (quality is light) concurrently simultaneously, pure titanium has good plasticity, it tough Property more than 2 times of pure iron, heat-resisting and corrosion resistance is also fine.Since titanium there are these advantages, rare gold outstanding is promoted it as Category, titanium and its alloy are first utilized in manufacture aircraft, rocket, guided missile, naval vessels etc., are widely used in chemical industry and petroleum again later Department；So not only increasing resource utilization to the recycling of the titanium of noble metal in ore dressing, and help to improve the warp for selecting factory Ji benefit.
Furthermore vanadium is currently mainly by China, and Russia, four South Africa, New Zealand country's productions, yield is far below the whole world To the demand of vanadium, market value is considerable.
Many iron ore mines, the main species of iron ore are vanadium titano-magnetite, and the vanadium titano-magnetite of certain areas also companion Have a large amount of apatite, i.e. ore is apatite-vanadium titano-magnetite, the iron of this kind of ore about 2/3rds with ilmenite and The form of titanomagnetite exists, remaining iron mainly exists in the form of pyroxene, a small amount of iron preservation garnet, allochite, In chlorite, the magnetic iron ore in these regional mines also contains a certain amount of magnalium, and the general iron content of ore is 15% or so, iron Matter grade is 68%, is Ultra-low-grade magnetite far below the theoretical Iron grade of magnetic iron ore 72.4%.P2O5Mainly with the shape of apatite Formula exists, and a small amount of preservation is in mica, P2O5Content be generally 2%-3% or more.TiO in ore2Mainly with the shape of ilmenite Formula exists, TiO2Content between 3%-8%.V2O5Main preservation in titanomagnetite with intergrowth of crystals, with vanadium iron spinelle Form exist, chemical formula is generally FeV2O4, this kind of vanadium iron spinelle be generally enriched with, V in ore with the enrichment of iron2O5 Content be 0.3-0.8%, if this part vanadium in ore can be extracted separate will greatly increase this kind of ore Comprehensive resources utilization rate, greatly improves economic benefit.So it is lower in view of the mine Iron grade, such as only recycle iron mineral, it will be difficult to Preferable economic benefit is obtained, this TiO that just seems2It is more necessary with effective recycling of vanadium.
In European Region and other developed countries, to P in Iron concentrate2O5Content have strict demand, generally mustn't be more than 0.05%, far more than P in China's Iron concentrate2O5Minimum content can requirement between 0.1~0.4%.
It can be seen that the green ore Iron grade is lower, P2O5Content it is higher, magnetic iron ore geologic grade is lower, in Iron concentrate Iron grade be difficult to improve, to P in Iron concentrate on international market2O5Content requirement it is very strict, this all gives this ore resource Utilization bring difficulty.And it is lower in view of the mine Iron grade, such as only recycle iron mineral, it will be difficult to obtain preferable economic effect Benefit, this TiO that just seems2It is more necessary with effective recycling of vanadium.
It is therefore necessary to develop one kind can effectively improve Iron grade in Iron concentrate, P in Iron concentrate is effectively reduced2O5Contain Amount, and can effectively recycle TiO2Miscellaneous ore-dressing technique drops with the apatite vanadium titano-magnetite of vanadium.
