Description
Technical field
The present invention relates to a kind of beneficiation inhibitor, more particularly to one kind are to quartzy gangue quartz molybdenite and pyrite associated minerals
Stone carries out molybdenum sulphur and mixes floating suppression particulate silicate gangue special efficacy composite inhibitor.
Background technology
To belonging to the molybdenum deposit of high quartz gangue quartz, the wherein occurrence status of molybdenum mainly based on the molybdenite of microfine,
Gangue mineral is mainly quartz, potassium feldspar, albite, muscovite, biotite etc., and containing being also easy to produce the clay pit of shale on a small quantity
Thing etc..Molybdenite in raw ore in fine microcrystalline or platy-monocrystal with muscovite or sericite symbiosis in comprising shape structure and
Microfine disseminated structure (is wrapped up in gangue mineral).Molybdenite part in because of raw ore with fine grain teeth cloth or explanation symbiosis in
It is wrapped among easy-floating gangue between gangue mineral or in particulate parcel state, this comprehensive recovery to molybdenum has significant impact, with
When, because mainly recyclable mineral molybdenite and pyrite, in fine grain teeth cloth characteristic, they are to improve recovery rate in ore-dressing, are roughly selecting work
Fine grinding technology is adopted in industry, but fine grinding easily causes secondary mud in ore pulp to increase, and causes flotation of ore pulp environmental degradation.
The domestic and international main quartzy gangue inhibitor of molybdenite flotation mainly has following several at present：
1st, waterglass
The modulus of water glass for making inhibitor is usually 2.4.Selected modulus is in 2.4 waterglass, containing a certain amount of glue
Shape SiO2.In waterglass, these metso are strong base-weak acid salt, and in alkalescence in ore dressing medium, hydrolyze or dissociate generation
HSiO-3 and colloidal state SiO2 and H2SiO3 easily adsorb in quartz or silicate surfaces, are allowed to hydrophilic and suppressed, waterglass
Other gangue minerals (such as calcite etc.) are may also suppress, and is widely used in molybdenum ore dressing.
2nd, calgon (NaPO3) 6
Calgon is silicate and the good inhibitor of calcite, lime stone.It has been generally acknowledged that it can be with mineral surfaces
Calcium ion reacts, and generates precipitation.According to surveying and determination, in 20 DEG C of temperature below, every gram of calgon can be complexed 195mg calcium from
Son.
Both the above medicament is more satisfactory to the inhibition of silicate, but to quartzy gangue quartz molybdenite and pyrite companion
When rawore stone carries out flotation, a kind of suitable mode cannot be found all the time, cause molybdenum concentrate grade and the rate of recovery extremely low, to mine
Enterprise causes unnecessary loss.
Content of the invention
The present invention provides a kind of composite restrainer for suppressing particulate silicate gangue, to solve conventional method using a large amount of water
Glass is had adverse effect on to follow-up molybdenum sulphur detached job, the difficult problem of FLOTATION SEPARATION, moreover it is possible to while obtaining the qualified product of molybdenum
Product, improve the economic benefit of enterprise.
The present invention is adopted the technical scheme that：It is to be made up of the raw material of following weight percentage：
Sodium carboxymethylcellulose 85～95%, guar gum 5～15%.
Preferably：
It is to be made up of the raw material of following weight percentage：
Sodium carboxymethylcellulose 91%, guar gum 9%.
The principle of the present invention：
(1) general principle
Sodium carboxymethylcellulose and guar gum composite restrainer suppress easily floating fine-grained gangue mineral in raw ore, due to Guar
Glue is macromolecule organic inhibitor, has had flocculation concurrently, has helped the effect of worry, can achieve under less consumption to easily floating talcum,
Argillaceous suppression.Using sodium carboxymethylcellulose and guar gum composite restrainer to the silicate gangue of particulate in this sample ore compared with
Conventional waterglass more has a high efficiency, and with consumption is few, advantage that is not affecting later separation operation.
(2) fundamental property of sodium carboxymethylcellulose (CMC)
Sodium carboxymethylcellulose (CMC) belong to anionic cellulose ethers, outward appearance be white flock fiber dust, odorless without
Taste is nontoxic；Cold water or hot water is soluble in, the clear solution with certain viscosity is formed, solution is neutrality, dissolves in aqueous 60%
Ethanol or acetone soln.
(3) fundamental property of guar gum
Guar gum, main component are the galactomannans that glycosidic inkage is combined, white to khaki powder, can be dispersed in
Viscous fluid is formed in heat or cold water, and viscosity soprano in natural gum adds a small amount of sodium tetraborate and is then transformed into gel, and the aqueous solution is
Neutral.
(4) process features
Mix in floating flow process in molybdenum sulphur, the method using roughly selecting twice, on the premise of effectively silicate gangue is suppressed, is improved
Molybdenum sulfur recovery rate.
It is an advantage of the current invention that：When flotation is carried out to quartzy gangue quartz molybdenite with pyrite association ore, adopt
Composite restrainer of the present invention, takes to roughly select in flow process twice and successfully realizes molybdenum flotation, using the mixed floating, bulk concentrate of molybdenum sulphur again
Mill, molybdenum sulphur content separating test flow process achieve the flotation of molybdenum ore, and molybdenum concentrate grade reaches 32.15%, and the rate of recovery is 61.12%, suppression
The more conventional waterglass of the silicate gangue of particulate processed more has a high efficiency, and has that consumption is few, do not affect later separation operation
Advantage, for improve mine economic benefit, have very important significance.

Below by specific experiment example come the effect of the further present invention.
Ore properties：Inner Mongol molybdenum ore, the ore deposit belong to the molybdenum deposit of high quartz gangue quartz, wherein the occurrence status master of molybdenum
Will be based on the molybdenite of microfine, gangue mineral is mainly quartz, potassium feldspar, albite, muscovite, biotite etc., and contains
There is clay mineral for being also easy to produce shale on a small quantity etc..Molybdenite in raw ore is in fine microcrystalline or platy-monocrystal and white clouds simultaneously
In comprising shape structure and microfine disseminated structure (wrapping up in gangue mineral), the sample ore is mainly recyclable for female or sericite symbiosis
Metalliferous mineral be molybdenite and pyrite, the content of valuable element Mo, S is 0.18%, 1.03%, has reached industrial recyclable
Standard.
The technique of the present invention is comprised the following steps：This flotation operation takes mixed floating, the detached technological process of molybdenum sulphur of molybdenum sulphur：Mixed
Floating operation sweeps three smart flow processs for two thick two, under conditions of one section of corase grind is for -200 mesh 85.63%, using Na2CO3, carboxylic of the present invention
Sodium carboxymethylcellulose pyce and the composite restrainer of guar gum, roughly select collecting agent for MY, and foaming agent is 2# oil；Detached job is one thick two
Four smart operations are swept, it is the mixed floating concentrate of molybdenum sulphur to separate to ore deposit, through regrinding to -400 mesh 92.89%, using Na2S+QS is pyrite
Inhibitor, RM are the collecting agent of molybdenite in detached job, finally give molybdenum concntrate and iron concentrate.
Result of the test does not adopt the composite restrainer of the present invention compared to former produced on-site, i.e., is only capable of obtaining molybdenum concntrate Mo
Grade 11%, less than 30%, iron concentrate is less than 20%, and iron concentrate contains Mo for the Mo rate of recovery>0.75% production target has matter
Leap.The result of the test is also demonstrated using the superiority for recommending composite restrainer of the present invention, and former produced on-site index is shown in Table
