Description
Technical field
The invention belongs to beneficiation inhibitor technical fields, and in particular to a kind of molybdenite beneficiation inhibitor and its preparation side
Method.
Background technique
Molybdenite (MoS2) be a kind of important Mo resource industrial products output mineral, still, molybdenite often contains
Gangue, there are many kinds of gangues, common are mica, calcite, talcum, chlorite, graphite etc..The main component of mica has
SiO2、K2O、Al2O3, the main component of calcite is CaCO3, the main component of talcum is MgO, Al2O3, chlorite it is main at
It is divided into aluminosilicate.
Molybdenite crystal is in six side's stratiforms or plate structure, and interlayer is combined with the Van der Waals force between S-Mo-S, binding force
Weaker, when levigate, interlayer Van der Waals force is difficult to maintain molybdenite structure, and hydrophobic surface, therefore brightness are formed after interlayer faults
The native floatability of molybdenum ore is good, thus molybdenite generallys use floatation and carries out ore dressing.Flotation process of molybdenite is usually by brightness
Molybdenum ore is levigate to be made ore pulp, is then fed into flotation cell, the ore particle in ore pulp and bubble contact, collision, the good ore particle choosing of floatability
It attaches to selecting property bubble and is carried the mineralized froth layer for rising and becoming airwater mist cooling composition, through machinery scraping or from mine
Pulp noodle are overflowed, then are dehydrated, are dried to concentrate product.But due to the occurrence status of the molybdenite in the molybdenum deposit of different regions, embedding
Cloth granularity, embedding cloth relationship, gangue mineral composition have larger difference so that the molybdenum deposit of different sources exists in washability
Bigger difference, and when carrying out flotation, the gangues such as mica, talcum, calcite, chlorite, graphite due to more soft, easily by
It is levigate, it is easy bubble in inflation, whipping process, is attached on bubble, is floated to mineralized layer, on the one hand, it belongs to impurity, directly
On the other hand connecing the collecting for influencing molybdenite will cause mineralized layer foam viscosity and increases, make foam bonding expansion, and mobility becomes
Difference, the scraper plate in flotation device are scraped less than foam, and going on smoothly for floatation process is unfavorable for.
Currently, the main inhibitor of molybdenite flotation has sodium metasilicate, calgon both at home and abroad.Sodium metasilicate is as common
Beneficiation inhibitor, wherein containing a certain amount of glue SiO2, also have the HSiO that hydrolysis or dissociation generate3、H2SiO3, these substances
Silicate surfaces are all easily adsorbed on, are allowed to hydrophilic and suppressed, similarly, sodium metasilicate can also inhibit some other gangue mines
Object.Calgon is silicate and the good inhibitor of calcite, lime stone.It has been generally acknowledged that it can be with the calcium ion of mineral surfaces
It reacts, generates precipitating.Both the above medicine machine is more satisfactory to silicate inhibitory effect, but the inhibition to non-silicate gangue
Effect is not ideal enough.
Application No. is the patents of invention of CN201610929753.X to disclose a kind of combination for inhibiting particulate silicate gangue
Inhibitor.Inhibitor disclosed in the patent of invention is made of the raw material of following percentages: sodium carboxymethylcellulose 85-95%, Guar
Glue 5-15%.Guar gum is macromolecule organic inhibitor, has both the effect of flocculation, drainage, can be realized under less dosage to easy
The inhibition of floating talcum, clayey.Sodium carboxymethylcellulose and guar gum composite restrainer compare the efficiency of conventional waterglass
Higher, dosage is less.According to the description of the invention, the method for using roughing twice, before effectively inhibiting silicate gangue
Put, improve molybdenum sulfur recovery rate, substantially mainly for product be still silicate gangue.
Application No. is the patents of invention of CN201710265701.1 to disclose a kind of inhibition ore of easy floating gangue such as talcum
Composite restrainer and its application method.In inhibitor, sodium metasilicate: the formula of CD 1:1-1:3, CD are aluminum sulfate 30-60%, paste
Smart 10-20%, carboxymethyl cellulose (CMC) 20-40%.The composite restrainer can reduce talcum, mica, calcite, chlorite
The floatability of equal ore of easy floating gangue.But the technical solution of the disclosure of the invention does not fully consider foam viscosity to floatation process
Influence, when foam viscosity is excessive, can make easy-floating gangue, molybdenite bonding, can also be easier to bring easy-floating gangue into mine
Bubble foam layer reduces the selectivity of floatation process.
Therefore, it is necessary to find, one kind is applied widely, inhibitory effect is good, can reduce the molybdenite of mineralized layer foam viscosity
Beneficiation inhibitor.
Summary of the invention
In order to solve the problems, such as to propose in background technique, the present invention gives a kind of molybdenite beneficiation inhibitor first,
It is secondary, provide a kind of preparation method of molybdenite beneficiation inhibitor.
A kind of molybdenite beneficiation inhibitor: being made of A, B component and water, and the weight ratio of component A and B component is 1:1-1:
2.5, the weight ratio of the sum of weight of component A and B component and water is 1:19-3:17；
Wherein the parts by weight of the ingredient in component A and each ingredient are as follows:
80-95 parts of sodium metasilicate；
5-20 parts of guar gum；
The parts by weight of ingredient and each ingredient in B component are as follows:
50-80 parts of aluminum sulfate；
12 5-10 parts of hydrazine aluminum sulfate potassium；
15-30 parts of sodium carboxymethylcellulose；
5-15 parts of tannin extract；
10-25 parts of dextrin.
Preferably, sodium metasilicate used is industrial sodium metasilicate, oxidation of impurities aluminium therein, iron content below 0.32%.
Preferably, aluminum sulfate used is industrial aluminum sulphate, and iron content therein is below 0.01%.
Preferably, the mass fraction of 12 hydrazine aluminum sulfate potassium used is 99.5% or more.

A kind of preparation method of molybdenite beneficiation inhibitor, includes the following steps:
S1. component A and B component are then codissolved in water by formula weighing, are made into the aqueous solution of weight fraction 5-15%；
S2. aqueous solution obtained in S1 is stirred into homogeneous, obtains a kind of molybdenite beneficiation inhibitor.
In addition, ore inhibitor dosage per ton is 300 grams~900 grams.
Thinking of the invention is the selective absorption by each component in inhibitor, is adsorbed in various easy-floating gangue tables
Face, and make easy-floating gangue that there is hydrophily by hydrophilic group, thus avoid easy-floating gangue with bubble floating to mineralized froth layer,
And it can reduce or block the adsorption between easy-floating gangue and collecting agent.In addition, in inhibitor disclosed by the invention also
Containing 12 hydrazine aluminum sulfate potassium (i.e. alum), in molybdenite beneficiation inhibitor ingredient before, there is no alum ingredients.
Beneficial effects of the present invention are as follows: by by various component organic assemblings, so that mica, cunning contained in molybdenite
Stone, calcite, chlorite, graphite etc. easily can be formed moisture film on levigate, easily floating gangue, had good hydrophily, kept away
Hydrophobic blistering is exempted from, in addition, the use of tannin extract reduces ore pulp, foam viscosity, has also reduced or blocked between gangue and collecting agent
Suction-operated also improved catching for collecting agent to both solve the tacky craftsmanship problem of ore-dressing technique chats pulp foam
Produce effects rate, improve collecting molybdenum ore grade and the rate of recovery, with grade it is rough in the case where, 2-4 percentage can be improved in mineral recovery rate
Point, so that more concentrate are obtained, from the point of view of interior angle of obtaining employment, significant effect.
Specific embodiment
The present invention will be described combined with specific embodiments below, but the only description of the invention, rather than to the present invention
The limitation of technical solution, the technical solution that progress simple superposition, element are replaced on the basis of disclosed embodiment should all
