Description
Technical field
The present invention relates to mineral processing in copper ore floatation field more particularly to a kind of Copper Ores production return water purify work
Skill.
Background technique
Copper is national economy indispensable basic material and strategic resource as a kind of important non-ferrous metal.Copper mine
The widest ore-dressing technique of middle use that sorts of stone is flotation, and a large amount of production return water, the return water can be generated in floatation process
In containing collecting agents and the pine tar alcohols foaming agent such as a certain amount of solid suspension, xanthate class, amine, lipid, since environmental protection is wanted
It asks and is increasingly stringenter, these production return water can only return in production procedure.But with prolonged circulative accumulation, in return water
Remaining medicine component becomes increasingly complex, and pharmacy effect gradually fails, while poisonous and harmful element is more and more, and return water is caused to return
Reflux journey is in use, to occur that flotation is difficult to control, production target decline, line clogging and clear water usage amount steeply rise etc. existing
As it is very necessary for developing a kind of Copper Ores production return water purification method thus.
Summary of the invention
The present invention provides a kind of Copper Ores production return water purification method, to solve in return water remaining medicine component increasingly
Complexity, pharmacy effect gradually fail, and poisonous and harmful element is more and more, be no longer appropriate for using the problem of.
The technical solution adopted by the present invention is that: include the following steps:
A. Copper Ores production return water is delivered in high-efficiency thickener by Pulp pump, macromolecular chemical combination is added in the process
Object polyacrylamide；
B. the concentrator overflow water obtained in step a imports in the standing pond under illumination condition,
C. the water handled in stepb is delivered in high efficiency stirring tank 1 by pumping, while being led into high efficiency stirring tank 1
Enter air；
D. obtained water is delivered in next stage high efficiency stirring tank 2 after handling in step c, while from ozone generator to height
Ozone is imported in effect stirred tank 2, and tungstates is added；
E. the water handled in step d enters production flotation operation.
The polyacrylamide added in the step a is suspended flocculent, dosage 5-10mg/l.
Pond is stood in the step b handles the time under illumination condition as 5h-8h.
High efficiency stirring tank 1 has air delivery pipe and air distributor, mixing time 5min- in the step c
10min。
In the step d high efficiency stirring tank 2 have air delivery pipe and air distributor, mixing time 4min-8min,
Tungstates dosage is 35-55mg/l.
Final water obtained in the step e enters head-tank and returns to production procedure.
The present invention has carried out 4 grades of purifications to the return water in Copper Ores floatation process, when eliminating return water and entering production system
The harmful chemicals of the solid suspension and remainings that have an adverse effect to index, while having saved rinse dosage, ensure that life
The stability of production.The method of the present invention is scientific and reasonable, easy to operate, it is easy to accomplish, it has the advantage that compared with prior art
1. xanthate class, amine, lipid and pine tar alcohols that this method has effectively purified in Copper Ores production return water organise
Object medicament is closed, and reduces solid suspension content in return water, greatly reduces Copper Ores production return water Returning process to production
The influence of index.
2. high-efficiency thickener as first class purification process, flocculant polyacrylamide is added in return water, is eliminated back
It is pure before standing pond process to ensure that return water enters for the solid contents such as remaining copper concentrate, sludge and inevitable gangue in water
Degree.Return water is delivered to behind standing pond under the conditions of solar exposure, is returned Organic substance in water class floating agent and has been carried out preliminary drop
Solution, the return water after degradation are then strong using carrying out in high efficiency stirring tank 2 by carrying out pre-oxidizing stage in high efficiency stirring tank 1
Oxidation.
3. be equipped with air distributor in the high efficiency stirring tank used in the present invention, can strengthen air and ozone and return water it
Between interaction, while tungstates can accelerate the oxidation of ozone as catalyst, further ensure organic medicament
It is fully oxidized.
