Description
Technical field
The present invention relates to ore dressing flotation technology, more particularly to a kind of application of bydroxyethyl starch ether in fluorite flotation.
Background technology
China's fluorite resource mainly has single type fluorite deposit (point) more but reserves are small, with (common) raw type mineral deposit (point) number
Less and reserves are big, and association reserves substantially exceed the reserves of single type, and lean ore is more, and rich ore is few, and difficult ore dressing is more, and easy ore dressing is few.Therefore,
Above many reasons cause China's fluorite resource whole development producing level low.
The difficult point of fluorite is the effective of fluorite and quartz, calcite, barite and multi-metallic minerals for a long time
Separation, this is similar mainly due to fluorite, calcite, quartz, barite Surface Physical Chemistry property.And in more metal association fireflies
Fluorite is then influenceed significantly by medicament in stone ore, for example, need to typically add substantial amounts of waterglass to firefly in white tungsten floatation process
The gangue minerals such as stone carry out strong inhibition, cause fluorite mineral in floating Tungsten tailing to be strongly inhibited so that most of with (common) raw
Fluorite ore is not utilized effectively.Therefore, solve the problems, such as a big emphasis of the floating agent into fluorite.
So-called starch ether, just refer to that-the OH in starch molecular structure reacts amylogenic substituent ether with active material,
Mainly include hydroxyalkyl starch ether, carboxyalkyl starch ether, alkyl starches ether, unsaturated alkyl starch ether and cationic starch etc.,
Ethers starch product viscosity stability is good, is widely used in the fields such as papermaking, water process, weaving, medicine, detergent, but in ore deposit
Thing floating agent field yet there are no its application report.
The content of the invention
It is an object of the invention to provide a kind of application of bydroxyethyl starch ether in fluorite flotation, for current calcite
The problems such as complicated difficults such as type, barite type select the fluorite flotation concentrate rate of recovery of poor quality and effective relatively low, flotation of the invention
Inhibitor bydroxyethyl starch ether can suppress the flotation of the gangue minerals such as calcite and barite, significantly improve the mineral such as fluorite with
The separating effect of calcite, barite, solve the problems, such as that fluorite separates difficulty with calcite, barite gangue mineral, it can also be used to
The suppression of calcite, barite mineral in other floatation process.
Technical scheme：
A kind of application of bydroxyethyl starch ether in fluorite flotation, it can other side in the floatation process of fluorite ore ore
Xie Shi, barite effectively suppress.
A kind of method for floating of fluorite ore, comprises the following steps：Fluorite ore ore containing barite, calcite mineral is ground
Broken, in feed flotation device and stirring is sized mixing, then with HCl, NaOH or Na2CO3Regulation pH values of pulp >=7 are simultaneously stirred, then add hydroxyl second
Base starch ether inhibitor ensures its concentration for 20~200mg/L and stirs 2~5min；Collecting agent enuatrol is finally added, it is used
20~400mg/L is measured, it is reinflated to scrape bubble.
The fluorite ore ore grinds granularity as -74+38 μm.
The present invention has following innovative characteristicses and effect compared with common starch and other inhibitor：
(1) it is strong to the inhibitor ability of calcite, barite mineral, be advantageous to improve fluorite grade and recovery
Rate, shorten flotation flowsheet, it is horizontal to improve comprehensive utilization of resources.
Minal Study of flotation result shows, as inhibitor common starch concentration 20mg/L in ore pulp, fluorite, again
Spar, the Floatation Rate of calcite respectively may be about 91.5%, 60%, 57.6%；And it is suppression to use the bydroxyethyl starch ether with dosage
During preparation, the Floatation Rate of fluorite have dropped 2% or so, and barite and calcite almost all are suppressed, Floatation Rate close to zero,
Illustrate that bydroxyethyl starch ether has good rejection ability to barite and calcite.
The experiment of artificial mixed ore FLOTATION SEPARATION shows, is giving ore deposit fluorite：Barite mass ratio is 1：When 1, to ore deposit through once
FLOTATION SEPARATION, and CaF in flotation concentrate2Grade and the rate of recovery are respectively 87.5%, 89.6%；Giving ore deposit fluorite：Calcite matter
Amount is than being 1：When 1, to ore deposit through a FLOTATION SEPARATION, and CaF in flotation concentrate2Grade and the rate of recovery be respectively 90.5%,
87.5%；Illustrate that bydroxyethyl starch ether has good selective depression ability to barite and calcite, be that fluorite and weight are brilliant
Stone, effective inhibitor of Calcite by Flotation separation.
(2) contrasted with common starch, bydroxyethyl starch ether is advantageous to liquid medicine and prepares and add, stable performance.Commonly
Starch dissolution degree is small, and the easy moldy metamorphism of solution prepared, and gives out stink, and bydroxyethyl starch ether solubility is high, and its is molten
Liquid stable performance, storage time length.
(3) contrasted with other inhibitor, there is friendly environment, wide material sources, cheap, positive effect.Hydroxyl
Primary raw material starch source prepared by hydroxyethyl starch ether inhibitor belongs to regenerated resources, taken in agricultural product such as corn, rice, sweet potato
Not to the utmost, nexhaustible and wide material sources, cheap, it is small that it using residue is easy to degraded, environmental pollution.
