Description
Technical field:
The invention belongs to mine technology fields, are related to a kind of method of iron tailings recycling cobalt mineralss, and in particular to one kind is adopted
Iron tailings cobalt mineralss are recycled with desliming preenrichment-method for floating.
Background technique:
Mineral Resources in China rich reserves, great variety of goods, but occupancy volume per person be low and lean ore, difficult ore dressing are more, exploitation benefit
It is big, at high cost with difficulty.Therefore the great demand of the development of the national economy is faced, it would be desirable to reinforce mineral resources saving and pipe
Reason, carries forward vigorously Green Mine and green mining develops demostration area construction, implements mineral resources saving and comprehensive utilization demonstration work
Journey, mineral resources conservation and deposit engineering, improve mining mineral resource rate, recovery rate in ore-dressing and comprehensive utilization ratio.
Chinese overwhelming majority cobalt metal resource is associated resources, is recycled essentially as mine byproduct.It produced
Cheng Zhong causes production technology complicated, the rate of recovery is low, high production cost since grade is low.Mainly there is following four cobalt ore in the country
Stone: cupro-nickel cobalt ore, Cu-Co deposit, wairauite stone and asbolane ore.Different ore dressing sides need to be used for different main mineral products
Method.Wherein the iron cobalt separation in wairauite stone uses floatation, respectively obtains two products of cobalt iron concentrate and iron ore concentrate.
By abundant the study found that content is in tailing after the cobalt in wairauite stone is primarily present in magnetic separation
0.012%, grade is lower.This part tailing granularity is thinner, does not need ore grinding, can directly adopt method for floating Call Provision.But by
Thin mud content is more in tailing, and direct flotation reagent consumption amount is big, flotation is at high cost, and flowage structure is complicated, operation is steady
Qualitative difference.Therefore, it is necessary to a kind of new processes to recycle to cobalt mineralss.
Summary of the invention:
To solve the above-mentioned technical problem low and at high cost there are the cobalt rate of recovery, the present invention provides a kind of iron tailings recycling
The method of cobalt mineralss plays the role of preenrichment desliming again using cyclone, returns to poor valuable mineral resource low in iron tailings
Then this sharp fall of harvest is comprehensively utilized by what flotation can have an economic benefit.
The technical solution that the present invention solves technical problem is as follows:
A kind of method of iron tailings recycling cobalt mineralss, this method specifically comprise the following steps:
Step 1: the raw ore after iron ore magnetic separation, which enters cyclone, to carry out preenrichment and removes thin mud；
Step 2: the product of acquisition carries out roughing by sequentially adding regulator, collecting agent and foaming agent after sizing mixing again；
Step 3: the rougher concentration obtained by roughing carries out selected operation for the first time and obtains chats two and concentrate；By
Rougher tailings that roughing obtains is added collecting agent and foaming agent carries out scanning operation and obtains chats three and tailing, and tailing is excluded；
Step 4: it chats two that selected operation for the first time obtains and scans the chats three that operation obtains and is back to jointly slightly
The stage is selected to carry out operation；
Step 5: obtained concentrate is subjected to second of selected operation and obtains chats one and final concentrate；
Step 6: obtained chats one is back to progress operation of selected stage for the first time, and recycles final concentrate as most
Finished product.
Further, the cyclone selects hydrocyclone.
Further, the regulator selects waterglass；Collecting agent selects alkyl dithiocarbonic acids sodium；Foaming agent is selected
Flotation oil.
Compared with the prior art, the invention has the following beneficial effects: the present invention uses desliming preenrichment-flotation technique
Cobalt in method synthetical recovery iron tailings can remove the thin mud in 40% iron tailings by cyclone predictive desliming, in sand setting
Cobalt taste increase substantially；Material after desliming passes through one roughing, selected twice and once purging selection closed circuit floatation process
Process finally can get grade 4659.11ppm, and the rate of recovery 54.41%, technical-economic index is good.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and specific embodiments:
Fig. 1 is the process flow chart of iron tailings recycling cobalt mineralss in the present invention.
Specific embodiment
Embodiment 1
As shown in Figure 1, a kind of method of iron tailings recycling cobalt mineralss, this method specifically comprise the following steps:
Step 1: the raw ore after iron ore magnetic separation, which enters cyclone, to carry out preenrichment and removes thin mud；
Step 2: the product of acquisition carries out roughing by sequentially adding regulator, collecting agent and foaming agent after sizing mixing again；
Step 3: the rougher concentration obtained by roughing carries out selected operation for the first time and obtains chats two and concentrate；By
Rougher tailings that roughing obtains is added collecting agent and foaming agent carries out scanning operation and obtains chats three and tailing, and tailing is excluded；
Step 4: it chats two that selected operation for the first time obtains and scans the chats three that operation obtains and is back to jointly slightly
The stage is selected to carry out operation；
Step 5: obtained concentrate is subjected to second of selected operation and obtains chats one and final concentrate；
Step 6: obtained chats one is back to selected sessions for the first time and carries out operation, and recycle final concentrate at
For final products.
In the present embodiment, the cyclone selects hydrocyclone, is used as desliming device, passes through centrifugation and gravity
Ore particle is dished out, is separated with the thin mud in raw ore.
In this implementation, the regulator selects waterglass, and the effect of adjustable collecting agent and mineral while promotes non-desire
Floating fine-grained composition dispersion；Collecting agent selects the xanthate in alkyl dithiocarbonic acids sodium, recycles useful mineral；Foaming agent is selected
No. two flotation oils can stablize bubble and collecting agent eutectoid content on ore particle surface, and play synergistic effect.
In this method, the return of chats product carries out roughing and selected operation again respectively, forms closed circuit flow, in this way can be with
Improve the rate of recovery of metalliferous mineral.
The foregoing is merely a prefered embodiment of the invention, but scope of protection of the present invention is not limited thereto, any to be familiar with sheet
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by those skilled in the art, should all cover
Within protection scope of the present invention.Therefore, the protection scope that protection scope of the present invention should be defined with claim is
It is quasi-.
Place is not described in detail by the present invention, is the well-known technique of those skilled in the art of the present technique.
