Abstract
It is the present invention relates to a kind of zinc oxide ore intensified Daqu method, zinc oxide ore is levigate, order addition acid solution, vulcanized sodium, composite collector effect after carry out 1 roughing, roughing foam carry out 2 times it is selected, ore pulp is scanned through 2 times in initial separatory cell.This method preferably resolves the problem of current zinc oxide ore ammonium sulfide flotation recovery rate is low, foam is difficult to control to, and flotation recovery rate is up to 60~85%.
Description
Technical field
The present invention relates to a kind of zinc oxide ore intensified Daqu method, belong to Mineral Processing Engineering flotation field.
Background technology
China's zinc resource enriches, and zinc reserves occupy the 2nd, the world, and wherein zinc oxide ore proportion is larger.Zinc oxide ore
Key industry mineral have smithsonite, smithsonite, willemite etc..The processing method of zinc oxide ore mainly has flotation and wet-leaching two
Major class, wherein floatation mainly have vulcanization-amine with the main stream approach that its cost advantage is current processing zinc oxide ore, floatation
Method, vulcanization-xanthate method, fatty acid collecting agent direct flotation method, flocculation-floatation etc..Widely used vulcanization industrial at present-
Amine method, amine collector used is usually 12 carbon atoms and the fat primary amine of the above, such as lauryl amine, octadecylamine.However, oxygen
Change zinc ore to have the following disadvantages using aliphatic amine collector flotation：It is more sensitive to sludge and soluble-salt, when in ore
Flotation environment and index deteriorate when sludge content is higher, and flotation froth is extremely difficult by medicament and the armoring froth breaking of sludge joint, raw
The live flow of production is difficult to smooth progress.Substantial amounts of test data and production target show that the flotation recovery rate of zinc oxide ore is usual
Only 50~65%.The flotation of zinc oxide ore sulfidization-amine method why produce a large amount of be difficult to rupture foams main reason is that：
（1）The amine collector of Long carbon chain has good frothing capacity in itself, easily produces a large amount of foams；（2）Mineral surfaces are adsorbed
A large amount of electronegative sulphion groups and aobvious electropositive cationic amines collecting agent occur strong in flotation three-phase system
Electrically absorption.Therefore, the influence of sludge is overcome, primarily must be from floating agent.
The content of the invention
In order to improve the rate of recovery of zinc oxide ore, mitigate influence of the sludge to vulcanization-amine flotation, the invention provides one kind
The flotation new method of zinc oxide ore surface acid corrosion-efficient collecting of vulcanization-composite collector.Can significantly it be mitigated using this method
The influence of sludge in zinc oxide ore floatation process, ensures the smooth operation of flotation flowsheet, preferably reclaims Zinc oxide minerals.
The present invention is achieved through the following technical solutions：
Levigate extremely -200 mesh of zinc oxide ore are accounted for into 80~90wt%, pulp density is controlled in 25~40wt%, addition 200~
800g/t acid solutions stir 3~5min, the dissolving of Zinc oxide minerals surface is fully exposed surface zinc atom, then add 2~
6kg/t vulcanized sodium vulcanizes 3~6min, and 1 time is carried out slightly after being eventually adding 200~500g/t of composite collector effects, 2~5min
Choosing, roughing foam carry out 2 times it is selected, ore pulp is scanned through 2 times in initial separatory cell, refining process chats successively order return upper level make
Industry, order returns to upper level operation to the process foam of scanning successively, and flotation recovery rate is up to 60~85%.Whole flotation process
As shown in Figure 1.
Zinc grade should be greater than 4% in the zinc oxide ore.
The acid solution is hydrochloric acid solution.
The composite collector is the mixture of 2- amino -5- epoxide-benzenethiol sodium and lauryl amine, and 2- amino -5- is
The mass ratio of epoxide-benzenethiol sodium and lauryl amine is 3~6:1.
Epoxide-benzenethiol sodium structural formula is 2- amino -5- in the composite collector：,
Its preparation method is：（1）By 2- amino benzenethiols（SH-C6H4-NH2）With propylene in molar ratio 1:1 mixing and in acid condition
React 1h and obtain product A；（2）Reaction product A is transferred in closed compressive reaction device, oxygen is passed through, it is anti-at 110-120 DEG C
0.5h is answered, appropriate amount of acid and water is then added, 90 DEG C are heated to, continues to react 0.5h, sodium hydroxide to solution is added and shows alkalescence, instead
Deserved product B, extracts to obtain product C with ether；（3）By product C and bromo n-hexane in molar ratio 1:1 reacts to obtain purpose product.
The present invention has the advantages that：
（1）Using sour corrosion Zinc oxide minerals surface, it is allowed to expose more zinc atoms, is conducive to subsequent mineral surface and multiple
The chelations of 2- amino -5- between epoxide-benzenethiol sodium in collecting agent are closed, while the consumption of vulcanized sodium can also be reduced；
（2）Compared with conventional vulcanized-amine method, using Chelating Collectors 2- amino -5-, epoxide-benzenethiol sodium is used as master to this method
Body medicament, only adds a small amount of lauryl amine, and the easy froth breaking of flotation froth of generation can overcome or significantly mitigate zinc oxide ore flotation
During sludge influence, preferable floatation indicators can be obtained, while ensure that the smoothness of technological process.
Brief description of the drawings
Fig. 1 is present invention process flow chart.
