Description
Technical field
The invention belongs to technical field of mineral processing, and in particular to a kind of preparation for vulcanizing copper-molybdenum separating flotation inhibitor
And application.
Background technique
The inhibitor generallyd use in the FLOTATION SEPARATION of copper-molybdenum bulk concentrate is Cymag, but main existing for Cymag
Problem is that toxicity is big, cyanide wastewater is not degradable, big to human body and environmental hazard and dosage is big, causes copper-cobalt ore cost inclined
It is high.Therefore efficient, non-toxic or low-toxic inhibitor is selected to have important practical significance instead of Cymag.
Thioacetic acid has been shown in copper-cobalt ore using upper since selectivity is high, pollution is small, dosage is few, inhibitory effect is good for it
Its superiority is shown.Thioacetic acid can carry out flotation under relatively broad pH value, and action time is short, inhibit selectivity high,
Hypotoxicity and water solubility all promote its application industrially, are just showing that good development becomes in copper-cobalt ore industry
Gesture.Since vulcanized sodium stability is poor, dosage is big, and thioacetic acid higher cost, therefore develops new and effective cheap copper-molybdenum point
From the main direction of studying that inhibitor is still current copper-cobalt ore.It has been reported that and chitosan is used as copper-cobalt ore inhibitor, but press down
Effect processed needs the problem of being further increased.Chinese patent (CN105537002A) is that sulfhydrylization reagent is modified shell by research group
Glycan prepares thio chitosan, and is applied to the inhibitor of vulcanization copper-molybdenum separation of pulp concentrate.But in subsequent application
Although invention, the inhibitor have the floating molybdenum effect of suppression copper well, there is also products to be insoluble in water even weak acid, simultaneously synthesizing cost
Height, because of the inherently good depressing agent of thioacetic acid and chitosan, during the preparation process, by be filtered, washed by
Unreacted thioacetic acid and chitosan increase production cost further through drying.The present invention overcomes the deficiency of the invention,
Using the mixture of thioacetic acid and the esterification of chitosan as inhibitor product, form is colloidal cpd, is soluble in weak
The production technology of acid, product simplifies significantly, reduces the step for being filtered, washed, drying, simultaneous reactions temperature at room temperature into
Row, reaction time also greatly shorten.The inhibitor effect of product utilization thioacetic acid, chitosan and thio chitosan three,
It is more convenient in practical applications, equally there is preferable suppression copper to float molybdenum effect.
Summary of the invention
The purpose of the present invention is for deficiency existing for prior art, provide one kind have production cost it is low, using secure side
Just, the preparation and application of the inhibitor of vulcanization copper-molybdenum concentrate copper-cobalt ore flotation low in the pollution of the environment.
The purpose of the present invention is achieved by the following technical programs:
A kind of preparation method vulcanizing copper-molybdenum separating flotation inhibitor, it is characterised in that the suppression of the copper-molybdenum minerals separation
The preparation step of preparation is as follows: by percentage to the quality, weighing a certain amount of chitosan and is added in a certain amount of thioacetic acid, stir
Dissolution is mixed, adds in a certain amount of concentrated sulfuric acid, is stirred to react certain time at room temperature, be inhibited agent product.
The deacetylation of the chitosan is greater than or equal to 70%.
The chitosan and the mass ratio of thioacetic acid are 1:10~20.
The concentrated sulfuric acid is the 0.5~1.0% of gross mass.
The mixing time is 5~12h.
A kind of vulcanization copper-molybdenum separating flotation inhibitor is applied to the separation process of copper-molybdenum bulk concentrate, by the flotation
Inhibitor realizes the isolated copper concentrate of copper-molybdenum mineral and molybdenum concentrate as the inhibitor of copper mineral.
The copper-molybdenum bulk concentrate is that copper-molybdenum green ore is carried out flotation, obtained copper-molybdenum bulk concentrate.
The inhibitor of the copper is thio chitosan mixture, dosage 100~150g/t copper-molybdenum bulk concentrate.
Depressing agent of the present invention prepares thioacetic acid and chitosan generation esterification with better inhibition effect
At thio chitosan mixture.The inhibitor is by the thioacetic acid with better inhibition effect and contains active hydroxyl and amino
Chitosan macromolecular and esterification generate thio chitosan composition, as vulcanization copper-molybdenum bulk concentrate separation flotation,
There is preferable suppression copper to float the effect of molybdenum.
Compared with the existing technology, the present invention has following remarkable advantage:
1, the thio chitosan mixture that the copper sulfide molybdenum concentrate floatation inhibitor that the present invention synthesizes is used passes through sulfydryl second
With chitosan esterification, chitosan and Cu occur for acid2+Chelate is formed, and-SH group has stronger reproducibility, Cu+With-
SH combination is more stable, and suppression copper effect is more obvious.
2, thio chitosan mixture thioacetic acid, chitosan and the thio chitosan synthesized, it is any former in synthesis
Material does not lose, and gives full play to the inhibitor effect of each substance.
3, synthesis technology is mild, easy to operate, and manufacturing cost is low, and effect is good.
Detailed description of the invention
Fig. 1 shows thio chitosan synthetic route.
