Description
One, technical field
The present invention relates to a kind of preparation methods of Wolframite agent, especially for the system of Wolframite collecting agent
Preparation Method.
Two, background technology
It is typically all both at home and abroad at present to be recycled using gravity separation method to the ore dressing of coarse grain wolframite, the rate of recovery of wolframite is most
45% hereinafter, loss late is larger；To the wolframite of fine fraction wolframite especially micro-size fraction, domestic and international ore dressing is main at present
With gravity treatment, the methods of again-floating process integration Wolframite is recycled, but since complex process or floating agent select
Property is not strong, does not still find preferable recovery method at present.For wolframite fine size, grade is low, contains in gangue mineral
A large amount of quartz and thin mud, the annual fine fraction wolframite value being lost in tailing is tens billion of, as can will be micro- using method for floating
Fine wolframite is detached with other impure minerals, this has important practical significance to the recycling of wolframite resource.
Three, invention content
The purpose of the present invention is to provide a kind of preparation method of Wolframite agent, the collecting agent being prepared into this method
It can realize that wolframite efficient flotation separation recycles.
The present invention realizes above-mentioned purpose using following technical scheme：A kind of preparation method of Wolframite agent, including such as
Lower step：First in mass ratio=1~2 by oleic acid and sodium methanesulfonate:1~3 is stirred 1 hour to obtain solution 1 at normal temperatures,
Then in mass ratio=1~2 by ethylenediamine:3~7 are slowly added in solution 1, are stirred to react under the conditions of 85~90 DEG C of temperature
2.5~3 hours obtained solutions 2, the brown color of gained after finally adding the sodium hydroxide of mass percentage concentration 10~15% to neutralize again
Translucent thick liquid is the Wolframite agent.
Slurry pH is 9~9.5 when flotation；In floatation process, gangue is added after ore ore grinding to mineral monomer is dissociated
Inhibitor 800~1000g/t of waterglass, then be added activator 300~400g/t of plumbi nitras, then add the collecting agent 800~
1000g/t, finally plus the agent 110~130g/t of 2# oil that spumes carries out collecting to wolframite.
In use, the collecting agent is first configured to 10% solution.
Unless otherwise stated, percentage of the present invention is mass percent, and the sum of each component content percentage is
100%.
Particularly advantage of the invention is：
1, using the collecting agent that is prepared into of the present invention can collecting wolframite, it is soluble easily in water, and have good selectivity
And resistance to low temperature.
2, dosing is few.
Four, specific implementation mode
Technical scheme of the present invention is further described below by way of specific embodiment.
Embodiment 1
One example of the preparation method of Wolframite agent of the present invention, includes the following steps：
First in mass ratio=1 by oleic acid and sodium methanesulfonate:1 is stirred 1 hour to obtain solution 1 at normal temperatures, then
In mass ratio=1 by ethylenediamine:3 are slowly added in solution 1, are stirred to react under the conditions of temperature is 85 DEG C and are made within 2.5 hours molten
Liquid 2, the translucent thick liquid of brown color of gained is institute after finally mass percentage concentration being added to be neutralized for 10% sodium hydroxide again
State Wolframite agent.
Embodiment 2
Another example of the preparation method of Wolframite agent of the present invention, includes the following steps：
First in mass ratio=2 by oleic acid and sodium methanesulfonate:3 are stirred 1 hour to obtain solution 1 at normal temperatures, then
In mass ratio=2 by ethylenediamine:7 are slowly added in solution 1, and 3 hours obtained solutions 2 are stirred to react under the conditions of 90 DEG C of temperature,
The translucent thick liquid of brown color of gained is described black after finally the sodium hydroxide that mass percentage concentration is 15% being added to neutralize again
Tungsten ore collecting agent.
Embodiment 3
The present embodiment is an application example of the Wolframite agent in Flotation Wolframite.
1, raw mineral materials：
W content is 0.37% in ore used, dioxide-containing silica 13.54%, iron content 15.75%, object phase point
Analysis shows that tungsten mainly exists in the form of wolframite, separately there is a small amount of scheelite；Gangue mineral mainly exists with silicate patterns, separately
There are segment magnet mine and goethite.
2. floating agent and operating condition:
In floatation process, after ore ore grinding to mineral monomer is dissociated, sodium carbonate is added and disperses and inhibit arteries and veins with waterglass
Stone ore object, then plumbi nitras is added to activate wolframite, finally plus the collecting agent carries out collecting to wolframite and obtains tungsten concentrate product.Experiment
The result shows that can effectively recycle wolframite using process above and agentia condition；Under the conditions of being 0.37% to mine W content,
Scanned twice by one roughing it is selected twice, obtain tungstic acid content be 54.21%, the tungsten concentrate of the rate of recovery 79.57%.
