Description
One, technical field
The present invention relates to the preparation method of a kind of Wolframite agent, especially for the system of Wolframite collecting agent
Preparation Method.
Two, background technology
Ore dressing to coarse grain wolframite the most both at home and abroad is typically all and uses gravity separation method to reclaim, and the response rate of wolframite is most
Below 45%, loss rate is bigger；Wolframite ore dressing both at home and abroad at present to fine fraction wolframite particularly micro-size fraction is main
By methods such as gravity treatment, weight-floating process integrations, Wolframite is reclaimed, but owing to complex process or floating agent select
Property strong, the most do not find preferable recovery method., gangue mineral low for wolframite fine size, grade contains
A large amount of quartz and thin mud, the fine fraction wolframite in mine tailing that runs off every year is worth tens billion of, if using method for floating by micro-
Fine wolframite separates with other impure mineral, and the recovery of wolframite resource is had important practical significance by this.
Three, summary of the invention
It is an object of the invention to provide the preparation method of a kind of Wolframite agent, the collecting agent being prepared into by the method
It is capable of wolframite efficient flotation separation to reclaim.
The present invention is attained in that the preparation method of a kind of Wolframite agent by the following technical solutions, including such as
Lower step: first oleic acid is stirred at normal temperatures with novalgin in mass ratio=1～2:1～3 and mix 1 hour to obtain solution 1,
Then ethylenediamine in mass ratio=1～2:3～7 is slowly added in solution 1, stirring reaction under the conditions of temperature 85～90 DEG C
2.5～3 hours obtained solutions 2, add the most again mass percentage concentration 10～15% sodium hydroxide in and the brown color of rear gained
Translucent thick liquid is described Wolframite agent.
During flotation, slurry pH is 9～9.5；In floatation process, after being dissociated by Ore ore grinding, add stone-like pulse to mineral monomer
Inhibitor waterglass 800～1000g/t, is subsequently adding activator plumbi nitras 300～400g/t, then add described collecting agent 800～
1000g/t, finally adds the agent 2# oil 110～130g/t that spumes and wolframite is carried out collecting.
During use, first described collecting agent is configured to 10% solution.
Unless otherwise indicated, percentage ratio of the present invention is mass percent, and each constituent content percent sum is
100%.
Particularly advantage of the invention is:
1, use the collecting agent that is prepared into of the present invention can collecting wolframite, soluble in water, and there is good selectivity
And resistance to low temperature.
2, dosing is few.
Four, detailed description of the invention
Below by way of specific embodiment, technical scheme is further described.
Embodiment 1
One example of the preparation method of Wolframite agent of the present invention, comprises the following steps:
First by oleic acid and novalgin in mass ratio=1:1 stirs at normal temperatures and mixes 1 hour to obtain solution 1, then
By ethylenediamine in mass ratio=1:3 is slowly added in solution 1, under the conditions of temperature is 85 DEG C, stirring reaction prepares molten in 2.5 hours
Liquid 2, adds in the sodium hydroxide that mass percentage concentration is 10% the most again and the translucent thick liquid of brown color of rear gained is institute
State Wolframite agent.
Embodiment 2
Another example of the preparation method of Wolframite agent of the present invention, comprises the following steps:
First by oleic acid and novalgin in mass ratio=2:3 stirs at normal temperatures and mixes 1 hour to obtain solution 1, then
By ethylenediamine in mass ratio=2:7 is slowly added in solution 1,3 hours obtained solutions 2 of stirring reaction under the conditions of temperature 90 DEG C,
Finally add in the sodium hydroxide that mass percentage concentration is 15% again and the translucent thick liquid of brown color of rear gained is described black
Tungsten ore collecting agent.
Embodiment 3
The present embodiment is a described Wolframite agent application example in Flotation Wolframite.
1, raw mineral materials:
In Ore used, W content is 0.37%, and dioxide-containing silica is 13.54%, iron content is 15.75%, and thing divides mutually
Analysis shows, tungsten mainly exists with wolframite form, separately has a small amount of scheelite；Gangue mineral mainly exists with silicate patterns, separately
There are segment magnet ore deposit and goethitum.
2. floating agent and operating condition:
In floatation process, after being dissociated to mineral monomer by Ore ore grinding, add sodium carbonate and waterglass dispersion and suppression arteries and veins
Stone ore thing, then add plumbi nitras activation wolframite, finally add described collecting agent and wolframite is carried out collecting obtain tungsten concentrate product.Test
Result shows that employing process above and agentia condition can efficient recovery wolframites；Under the conditions of being 0.37% to ore deposit W content,
Through one roughing scan for twice twice selected, it is thus achieved that Tungstic anhydride. content is 54.21%, the tungsten concentrate of the response rate 79.57%.
Embodiment 4
