Abstract
The present invention discloses a kind of composite restrainer of pyrite, its component and weight percent are: citric acid 10 ~ 80%, lime 10 ~ 80%, potassium permanganate 5 ~ 40%；Composite restrainer of the present invention strengthens the inhibiting effect to pyrite by the synergistic effect between medicament, the inhibition that can be used in shallow crust structures as pyrite has reagent consumption few for conventional pyrite inhibitor, rejection ability is strong, cheap advantage；There is preferable inhibitory effect particularly with the pyrite after activated by copper ions, the combination medicament solubility is good, nontoxic, environmentally friendly.
Description
Technical field
The present invention relates to a kind of composite restrainers of pyrite, belong to technical field of mineral processing.
Background technique
Pyrite is main objectionable impurities of the preservation in the concentrate product such as copper, lead, zinc.In separation multi-metal sulfide
When, be usually present copper ion etc. to the activating ion of pyrite in flotation pulp, therefore both at home and abroad never interruption to inhibiting yellow
The research of iron ore.In lead zinc sulfide minerals flotation separation, according to the difference of ore properties, common flotation flowsheet has lead, zinc, sulphur
Successively selective flotation flowsheet；The preferentially mixed floating separation process again of floating lead, zinc-sulphur；Lead-zinc part is mixed floating to be separated again, zinc-sulphur is mixed
It is floating to separate again and iso-floatability circuit.No matter which kind of flowage structure practice selects, and studying effective pyrite inhibitor is all a weight
Want direction.At present industrial production realize lead zinc sulfide separation floatation process in pyrite inhibitor can be divided into lime, cyanide,
Six major class such as reductant-oxidant, organic inhibitor, inorganic inhibitor and microbial inhibitor, wherein lime is most common yellow iron
Mine inhibitor.
It is that widest sulfide-bearing deposits technique is used to obtain in production using lime as the high-alkali technique of representative.Lime is molten
Highly basic is formed in water, improves slurry pH, generate hydroxide in mineral surfaces and forms calcium film, realizes the suppression to sulfide mineral
System.
Although lime can effectively inhibit pyrite, on the other hand due to largely also producing a series of ask using lime
Topic:
1) in High Alkalinity Medium, lime consumption it is big and must cream processed complicate production technology；Foam is viscous, and entrainment sludge influences essence more
Mineral amount；The easy fouling of lime, consolidation block pipeline, are unfavorable for production operation and index is stablized.
2) after lime consumption is big, some main metals also will receive inhibition, can be suppressed after slightly aoxidizing such as galena surface,
Influence the raising of the lead concentrate rate of recovery；Pyrite inhibits less than good again if lime consumption is few, so that concentrate quality drops
It is low, cause both ends difficult.
3) cause to select the difficulty of sulphur.After pyrite is inhibited by lime, difficulty of swimming, it is often necessary to use a large amount of sulfuric acid formula
Acid water activation, but since sulfuric acid corrosion resistance is strong, fugitive toxophoric gas, operating condition is badly and for the ore of carbonate containing gangue
It can consume excessive, so that many not high mines of pyrite content can not recycle yellow iron because of cost problem, be discarded in
It results in waste of resources in Tailings Dam.
4) it is unfavorable for the recycling of noble metal.In High Alkalinity Medium, lime has not the noble metals such as gold, silver, molybdenum in ore
With the inhibiting effect of degree, so that these noble metals cannot be recycled effectively.
Therefore, it develops pyrite inhibitor efficient, that selectivity is good to replace lime or reduce the dosage of lime, to me
The synthetical recovery of state's copper ore resource is of great significance.
Summary of the invention
The present invention inhibits pyrite there are poor selectivity for existing lime, and lime presses down pyrite in the environment of copper ion
The problem of effect difference processed provides a kind of composite restrainer for pyrite, and the composite restrainer is to there are the mines of copper ion
Pyrite has preferable inhibitory effect in slurry, it is particularly possible to realize efficiently separating for chalcopyrite and pyrite, improve copper sulphur content
From effect.
To achieve the goals above, the invention is realized by the following technical scheme:
A kind of composite restrainer of pyrite, component and weight percent are as follows: citric acid 10 ~ 80%, lime 10 ~ 80%, permanganic acid
Potassium 5 ~ 40%.
The additive amount of the composite restrainer is 100g/t ~ 3000g/t.
2 ~ 10 minutes inhibitory effects that can be got well are acted on after the composite restrainer addition.
The present invention has the advantages that:
(1) three kinds of medicaments used in composite restrainer of the present invention are citric acid, lime, potassium permanganate, are all conventional dose, are easy
It obtains, it is cheap.
(2) composite restrainer of the present invention has stronger rejection ability to pyrite, only need to add a small amount of inhibitor just
Ideal inhibitory effect can be obtained, cost is lower.
(3) composite restrainer of the present invention has preferable selective depression effect for the pyrite in Differential flotation of copper and sulphur, and
And it is easy to operate, it is easy to accomplish.
