Description
Technical field
The present invention relates to titanium separation method fields, more particularly to v-ti magnetite tailing recycling titanium separation method.
Background technique
China v-ti magnetite mineral deposit is widely distributed, rich reserves, and the third position of the national iron ore of reserves and yield residence has been visited
98.3 hundred million tons of bright reserves, prospective reserves are mainly distributed on Panxi, Sichuan (Panzhihua-Xichang) area, Hebei up to 30,000,000,000 tons or more
Chengde area, Hanzhong Area of Shaanxi, Hubei Yun county sun, Xiangyang area, Shandong Linyi, Xingning of Guangdong Province and Shanxi Dai County, Chaoyang
Equal areas.Wherein, Pan Xi (Panzhihua-Xichang) area is the Main Metallogenic band of China's vanadium titano-magnetite, and similar in the world
One of the important producing region in mineral deposit, north and south are about 300km, have verified at large-scale, oversized mineral deposit 7, at medium-sized mineral deposit 6.Navajoite money
Source is more, total reserves V2O525960000 tons, occupy the 3rd, the world.Navajoite mainly originate in magma lithotype vanadium titano-magnetite bed it
In, as associated minerals output.Navajoite is mainly Cambrian Black Shale-type navajoite as independent deposit.Navajoite is distributed more widely,
There are proved reserves in 19 provinces (area), Sichuan vanadium reserves rank first in the whole country, and account for the 49% of gross reserves;Hunan, Anhui, Guangxi, lake
North, Shandong, Gansu etc. save (area) and take second place.Vanadium titano-magnetite is with being distributed mainly on Sichuan-Xichang Region and Chengde
Area, Black Shale-type navajoite are distributed mainly on Hunan, Hubei Province, Anhui, one band of Jiangxi.
Vanadium titano-magnetite rock mass is divided into basic rock (gabbro) type and basic-ultrabasic rock (gabbro-pyroxenite-brightness
Rock) type two major classes, the important sources of iron, and the Multicomponents such as the vanadium of association, titanium, chromium, cobalt, nickel, platinum family and scandium are not only, are had
There is very high comprehensive utilization value.
Titanium is a kind of rare metal, it, which exists, in nature disperses and be difficult to extract, it has many excellent performances.Liquid
State titanium can almost dissolve all metals, therefore can form alloy with various metals.It is tough and tensile that titanium steel obtained in steel is added in titanium
And aircraft people more than 100 than the aircraft overloading passenger that same weight is made in other metals are made in high resilience, titanium alloy.It is manufactured latent
Ship, can anti-seawater corrosion and deep layer pressure, submerged depth than stainless steel submarine increase by 80%.Meanwhile titanium is nonmagnetic,
It will not be found that there is good anti-monitoring effect by submarine mine.Titanium also has " one's own object " property.In human body, secretion can be resisted
Corrosion and nontoxic, any method for disinfection is all adapted to.Therefore it is widely used in medical instrument processed, artificial femoral articulation processed, knee close
Section, shoulder joint, the side of body joint, cranium, active heart valve, skeletal fixation folder.When new meat fiber ring packet is on these " titanium bones "
When, these titanium bones begin to maintain the normal activity of human body.
And in actual industrial production, when dressing plant's concentrate selection, is poor to the rate of recovery of ilmenite concentrate, and there are still have titanium in tailing
Concentrate is not selected, as Tailings Slurry is discharged into Tailings Dam.And ore belongs to non-renewable resources, can increasingly reduce with exploitation, such as
Fruit more fully becomes the unique channel solved the problems, such as using existing resource.
Summary of the invention
The object of the present invention is to provide a kind of v-ti magnetite tailing recycling titanium separation methods, can be by v-ti magnetite tailing again
Titanium is selected in recycling, makes full use of the natural resources.
In order to solve the above technical problems, one technical scheme adopted by the invention is that:
A kind of v-ti magnetite tailing recycling titanium separation method is provided, including the following steps:
(1) v-ti magnetite tailing is subjected to progress high intensity magnetic separation after weak magnetic removes iron and obtains high intensity magnetic mineral;
(2) high intensity magnetic mineral be dehydrated after gravity treatment roughing, gravity treatment are selected up to titanium chats.
The iron tailings of low-grade vanadium titano is the vanadium titano-magnetite tailing by being conventionally treated in this field.
Further, it is 2300~3000Gs that the weak magnetic, which removes the field strength of iron,.
Further, the background lectromagnetism field of the high intensity magnetic separation is 4000~10000Gs.
Further, it is 2500~2800Gs that the weak magnetic, which removes the field strength of iron,.
Further, the field strength of the high intensity magnetic separation is 5500~6500Gs.
Further, the v-ti magnetite tailing includes coarse fraction mineral and fine-grained minerals.
It can be ability that the v-ti magnetite tailing, which is classified as raw material coarse fraction mineral aggregate and the method for raw ore fine fraction mineral aggregate,
Common method in domain requires as long as raw ore coarse fraction mineral aggregate and raw ore fine fraction mineral aggregate is made to meet recycling.Such as it is logical
It crosses inclined plate concentration classification case classification and obtains raw ore coarse fraction mineral aggregate and raw ore fine fraction mineral aggregate.
Further, it when the v-ti magnetite tailing is coarse fraction mineral, is first carried out every Slag treatment before weak magnetic is except iron.
Further, the gravity treatment is using one or more progress in spiral chute, spiral concentrator and shaking table.
In one embodiment of the invention, the gravity treatment is carried out using spiral chute.
Further, the iron tailings of low-grade vanadium titano contains TiO2Grade is 3.0~12.0%.
The beneficial effects of the present invention are:
(1) titanium separation method process of the present invention is few, easy to operate, then is not necessarily to slurry concentrating can be directly entered production before selecting, then
Selecting technique is that magnetic separation aggravates choosing, hardly changes the mechanics index of physics such as tailings granularity, bulk density, internal friction angle, cohesive strength, and
Tailing pulp density remains unchanged after selecting again, consistent with the tailing pulp density of former v-ti magnetite Tailings Dam, therefore tailings is not present
Inconsistent situation is designed with former, Tailings Dam operational safety can be protected.
(2) v-ti magnetite tailing can be recycled by titanium separation method of the present invention, then the titanium chats TiO obtained after selecting2Product
Position is significantly improved compared with original debris, is taken full advantage of natural resources, while reducing pollution of the tailing to environment, is turned waste into wealth.
