Description
Technical field
The present invention relates to technical field of beneficiation, more particularly to a kind of depressing agent and preparation method and applications.
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.
The content of the invention
It is an object of the invention to provide a kind of depressing agent and preparation method and applications.For current calcite type,
The problems such as complicated difficults such as barite type select the fluorite flotation concentrate rate of recovery of poor quality and effective relatively low, flotation of the invention suppress
Agent (being modified using iron chloride to common starch, referred to as " iron starch ") can suppress the gangue minerals such as calcite and barite,
The mineral such as fluorite and calcite, the separating effect of barite are significantly improved, solve fluorite and calcite, barite gangue mineral point
The problem of from difficulty, it can also be used to the suppression of calcite, barite mineral in other floatation process.
Technical scheme：
A kind of depressing agent, i.e. iron starch, be by Qu Li Shui ︰ Dian Fen ︰ iron chloride three in mass ratio for 20~
What the ︰ 0.05~0.2 of 100 ︰ 1 mixing and heating water bath stirring reaction generated.
A kind of preparation method of depressing agent, first by deionized water, starch, iron chloride three successively in mass ratio 20~
The ︰ 0.05~0.2 of 100 ︰ 1 ratio is added in three-necked flask, and three-necked flask then is put into heating water bath in magnetic stirring apparatus again
Stirring reaction, mixing speed are 400~800r/min, and the stirring of water-bath temperature >=90 DEG C is changed into bronzing up to solution,
Final mean annual increment solution can be used to Study of flotation.
The depressing agent is effective inhibitor of calcite, barite mineral, is mainly used in fluorite ore ore
The suppression of calcite, barite in floatation process.Key step method is：By the fluorite containing barite, calcite gangue mineral
Ore deposit ore is ground, and in feed flotation device and the 1min that sizes mixing is stirred, then with HCl, NaOH or Na2CO3Regulation pH values of pulp >=6 are simultaneously stirred
2min is mixed, then adds inhibitor to ensure its drug concentration >=20mg/L and stir 3min, finally adds collecting agent oleic acid dosage 20
~400mg/L stirrings 3min, reinflated scrape bubble.
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 90%, 60%, 57%；And when use is inhibitor with the iron starch of dosage, firefly
The Floatation Rate of stone have dropped 2% or so, and barite and calcite almost all are suppressed, and Floatation Rate illustrates that iron forms sediment close to zero
Powder has good rejection ability to barite and calcite.
The experiment of artificial mixed ore FLOTATION SEPARATION shows, is giving ore deposit fluorite：Barite or calcite mass ratio are 1：When 1, i.e.,
Artificial mixed ore CaF2To ore deposit grade 50%, to ore deposit through a FLOTATION SEPARATION, the removal efficiency of barite or calcite is left 85%
The right side, and CaF in flotation concentrate2The rate of recovery >=87%, illustrate that iron starch has good selectivity suppression to barite and calcite
Ability processed, it is effective inhibitor that fluorite separates with barite, Calcite by Flotation.
(2) contrasted with common starch, the iron starch is advantageous to liquid medicine and prepares and add, stable performance.Common starch
Solubility is small, and the easy moldy metamorphism of solution prepared, and gives out stink, and iron starch dissolution degree is high, and its solution property is stable,
Storage time is grown.
(3) contrasted with other inhibitor, there is friendly environment, wide material sources, cheap, positive effect.Should
Primary raw material starch source prepared by iron starch inhibitor belongs to regenerated resources in agricultural product such as corn, rice, sweet potato, take no
To the greatest extent, nexhaustible and wide material sources, cheap, it is small that it using residue is easy to degraded, environmental pollution.
