Description
Technical field
The present invention relates to gangue separation fields, more specifically to the gangue seprating assistant method of pyrometallurgy.
Background technique
Pyrometallurgy is exactly that ore or concentrate are subjected to a series of physicochemical change process under the high temperature conditions, makes it
In metal separated with gangue or other impurities, and obtain the metallurgical method of metal, including roasting (or baking with agglomeration), melting,
The processes such as blowing, distillation and smart gold-plating, pyro-refining, molten-salt electrolysis.
For economic angle, the raw material of pyrometallurgy is mostly the higher gangue mineral of purity, and in nature
The gangue mineral ingredient of formation is not quite similar, and particularly, the unearthed gangue mineral in a pit is also likely to be present biggish gap,
Therefore need to carry out ore dressing to gangue money object before metallurgy, select the higher gangue mineral of purity to carry out metallurgy, and purity is lower
Gangue mineral can only do waste processing.
But metalliferous mineral belongs to non-renewable resources, and how much consumption is exactly to lose how many, for by tungsten ore, China
As tungsten ore big country in the world, the rich reserves of tungsten ore, and tungsten ore is in nature mainly with wolframite and two kinds of scheelite
Form exists, and wherein wolframite is easily purified and smelts and first utilized by people, the wolframite reserves in China also compared with horn of plenty,
But the initial stage exploited and utilized in wolframite, due to the technical restriction of gangue separation and pyrometallurgy, along with more extensive
Production method, cause the waste of a large amount of tungsten ore resource, partial metallurgical factory is even direct by tailing in order to save production cost
It is discharged into nature, it is without any processing, serious influence also is caused on environment while wasting vast resources, and in length
Up to after the more extensive wolframite metallurgical production of over half a century, also there is resource in the wolframite for being considered rich reserves originally
Deficient situation, people have to sight turning the scheelite for being difficult to purify and smelt.
Summary of the invention
1. technical problems to be solved
Aiming at the problems existing in the prior art, the purpose of the present invention is to provide the gangue seprating assistant sides of pyrometallurgy
Method, it may be implemented to increase the utilization rate of wolfram element in scheelite, during gangue mineral separation, for part W content
Gangue mineral that is higher but not meeting production requirement carries out postsearch screening, is not easy to result in waste of resources, is the current mining industry in China
An important ring in circular economy meets the recyclable production of current country and the fundamental state policy of built environment friendly society, though
So a little higher than current more extensive production method of meeting in terms of production cost of the present invention, but be also the following mining industry cycle development
An important directions.
2. technical solution
To solve the above problems, the present invention adopts the following technical scheme that.
The gangue seprating assistant method of pyrometallurgy, including the following steps are included:
Scheelite is crushed to the size of suitable differential separation by S1, coarse crushing, staff with mineral breaker.
S2, washup, staff clean the scheelite Jing Guo coarse crushing, the impurity for scheelite surface attachment of going out.
S3, differential separation, cleaned scheelite and clear water are added in mineral centrifuge staff together, carry out from
Heart separation, obtains the gangue mineral and waste tailing of the white tungsten stone of target.
S4, waste recovery after tailing is carried out waste recovery processing by staff, repeat S1-S3, carry out to tailing secondary
Separation.
S5, ore grinding, staff cut after being dried from the gangue mineral for the white tungsten stone that the separation of S3 differential obtains
It cuts or shaping, the shape and size of the gangue mineral of white tungsten stone is made to reach compound back production requirement.
S6, fluorescence sorting, staff utilizes ultraviolet lamp, fluorescence detection device and automatic discharging device, right
Scheelite gangue mineral carries out primary election, testing by taking 80-120 millimeters of partial size scheelites as an example as a result, charging grade is 0.60%
WO3, barren rock grade 0.10%WO3, WO in barren rock3Distributive law be 7.0%, barren rock mine amount percentage is about 55%.
S7, flotation, the flotation of scheelite are carried out in alkaline medium, with sodium carbonate by pH to the 9-10.5 of ore pulp, are added
Enter waterglass as inhibitor, adds oxidized paraffin wax soap as capturing agent, the ore pulp formed by one ton of raw ore needs to be added in terms of coming
The inhibitor waterglass and 200-400 grams of capturing agent oxidized paraffin wax soap that 500-2000 grams of modulus is 2.2-3.
The utilization rate that wolfram element in increase scheelite may be implemented, during gangue mineral separation, for part tungsten
Content is higher but does not meet the progress postsearch screening of the gangue mineral of production requirement, is not easy to result in waste of resources, is that China is current
An important ring in Mining Recycling Economy meets the recyclable production of current country and the basic state of built environment friendly society
Plan is also that the following mining industry follows although a little higher than current more extensive production method of meeting in terms of production cost of the present invention
One important directions of ring development.

The partial size of tungsten ore gangue mineral is about 50-150mm, improves the sharpness of separation of S6 fluorescence sorting, reduces the work of fluorescence sorting machine
Difficulty.
S6, fluorescence sorting, staff utilizes ultraviolet lamp, fluorescence detection device and automatic discharging device, right
Scheelite gangue mineral carries out primary election, testing by taking 80-120 millimeters of partial size scheelites as an example as a result, charging grade is 0.60%
WO3, barren rock grade 0.10%WO3, WO in barren rock3Distributive law be 7.0%, barren rock mine amount percentage is about 55%.
S7, flotation, the flotation of scheelite are carried out in alkaline medium, with sodium carbonate by pH to the 9-10.5 of ore pulp, are added
Enter waterglass as inhibitor, adds oxidized paraffin wax soap as capturing agent, the ore pulp formed by one ton of raw ore needs to be added in terms of coming
500-2000 grams of modulus is the inhibitor waterglass of 2.2-3, can mix a small amount of ferrous sulfate in waterglass, and it is floating can to improve S7
The selectivity chosen improves the flotation effect of scheelite and 200-400 grams of capturing agent oxidized paraffin wax soap, is carrying out 1 time
Carried out again after primary election 2-3 times scan with it is selected, obtain white tungsten rough concentrate and tailing, improve the flotation precision of S7 flotation, S7 is floating
Need to be ready work before selecting scheelite, since white tungsten bed mine generally entails sulphide ore, wherein molybdenite is especially common, therefore
General elder generation's Flotation of Sulfide Ores, rear fubai tungsten ore improve S7 flotation precision, reduce the difficulty of S7 flotation in the beneficiation method of scheelite
It spends, zinc sulfate and sodium carbonate can be selected as inhibitor during Flotation of Sulfide Ores in S7 flotation, avoid that cyanide is selected to make
For inhibitor, reduces and polluted caused by cyanide.
Further, the mineral centrifuge in S3 differential centrifugation includes vertical centrifugal ore selector bracket 1, vertical centrifugal ore dressing
Rotary drum 2 and motor 4 are connected on machine support 1, motor 4 is located at the side of rotary drum 2, is connected between rotary drum 2 and motor 4
