Description
Technical field
The present invention relates to a kind of carnallite production KCl method, and in particular to one kind from high boron carnallite
Except harmful element particulate boron compound, except the method that decomposition-floatation process production KCl is utilized after boron.
Background technology
Carnallite, molecular formula are KClMgCl2·6H2O, be it is a kind of produce the common raw material of potassium chloride, it has two kinds to deposit
In form, a kind of is the secondary carnallite that the primary carnallite and bittern salt pan evaporation of self-assembling formation is obtained.In light halogen
In the technique of stone production potassium chloride, cool technology-floatation process is technique more ripe at present, and more than 90% carnallite is all adopted
With technique productions KCl.
There are substantial amounts of potassium, the salt lake bittern of boron symbiosis in China Qinghai-Tibet Platean, rich in K+While B2O3Content is also higher.
In the evaporation process of salt pan, K+It is carnallite stage B to separate out the later stage2O3With alkali formula antifungin calcium compound（Alkali formula antifungin calcification
Compound is the compound containing B2O3 such as boromagnesite and borax cementing a kind of superfine granulation being wrapped to form in the evaporation process of salt pan
Compound）Form separate out, the compound fine size, most of exist in ore pulp with aerosol form, and KCl is produced to carnallite
Floatation process have a negative impact, be in particular in the following aspects, when influence floating agent addition, superfine alkali
The presence of formula antifungin calcium compound particle, causes the surface area of solid particle in ore pulp to increase, so as to cause floating agent
Consumption increases；Second, the presence of alkali formula antifungin calcium compound particle can make flotation froth tacky, bubble mobility is reduced, most
Foam is caused to emit groove eventually；Third, influenceing KCl separating effect, cause the KCl concentrate grades that floatingly select low, it is qualified to produce
KCl products；Fourth, the presence of particulate boron blocks filter paper filter cloth, the strainability of product is set to be deteriorated.It is such based on above reason
High boron carnallite production KCl turns into insoluble problem in professional domain.
Current high boron carnallite（B2O3 content >=1.5%）It is most of all discarded using less, it is to the very big of resource
Waste.Current reported boron removal technique be substantially acid system except boron and floatation remove boron, it is in flotation pulp that acid system, which removes boron,
Middle addition hydrochloric acid, alkali formula antifungin calcium compound is dissolved in mother liquor by acid, the method can be acidified mother liquor, arrange to salt pan
After cause environmental pollution.CN104163440A discloses a kind of earth's surface carnallite production KCl method, wherein including one section of light
Halogen stone pretreating process, primarily to the clay in removing carnallite.The patent removing process is complicated, long flow path, and operation is difficult
Spend larger, need to pass through two-stage desliming process could effectively remove clay in carnallite.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of high boron carnallite production KCl method, and technique is simpler
Single, the potassium rate of recovery is higher.
The present invention solves the technical scheme that its technical problem uses, a kind of high boron carnallite production KCl method, tool
Body comprises the following steps：
（1）Ore grinding：By high boron carnallite raw ore ore grinding；Make carnallite and boron compound fully dispersed in ore pulp；
High boron carnallite raw ore B2O3Content >=1.5wt%, have influence on the normal utilization of such carnallite.Ore grinding mass concentration is
50-65%, ore grinding mother liquor use the common saturation mother liquor of caused potassium chloride, epsomite, carnallite in the evaporation process of salt pan.Ore grinding is thin
Spend and account for more than 90wt% for -20 mesh.
（2）Size mixing dosing：With sizing mixing, mother liquor will be through step（1）High boron carnallite pulp density after ore grinding adjusted to 10~
15 wt %, while alkali metal phosphate is added, the ore pulp after must sizing mixing；
The mother liquor of sizing mixing is carnallite saturation mother liquor.The alkali metal phosphate is sodium tripolyphosphate, calgon by 1：
1-1.2 mass ratio compounding.Add alkali metal phosphate functions as dispersant to disperse the alkali formula antifungin in ore pulp
Calcium compound, reduce its adsorption in carnallite mineral.The dosage of alkali metal phosphate is 40~60mg/L ore pulps, herein
The volume calculating benchmark of ore pulp is that the ore pulp after mother liquor of sizing mixing is sized mixing is added in this step.Alkali metal phosphate can be configured to solution
Add.
（3）It is classified boron removal：Ore pulp after sizing mixing is pumped to desliming bucket and divides boron compound in mud device removing ore pulp, gained
Underflow is the low boron carnallite ore pulp of high concentration（The concentration of ore pulp is high, but Boron contents are low）；Gained overflow is the height of low concentration
Boron mother liquor（The concentration of ore pulp is low, but Boron contents are high）.
Ore pulp i.e. feed slurry concentration after sizing mixing is 10~15wt%.The low boron carnallite pulp density of gained high concentration
For 60~70wt%；The high boron mother liquid concentration of gained low concentration is 4~8wt%.
（4）High boron mother liquid disposal：Toward step（3）Add flocculant in the high boron mother liquor of gained to flocculate and settle, supernatant liquor
Return to step（2）Size mixing, lower sediment is discharged into tailing pit.
The flocculant is polyacrylamide；Dosage is the high boron mother liquors of 2~5mg/L.
（5）Decompose：By step（3）The low boron carnallite ore pulp of gained and water, washing mother liquor in mass ratio 1: 0.08~0.15:
0.10~0.18 mixing, is stirred at room temperature 40~60 minutes, and solid-liquid mixed ore pulp is obtained after decomposition；
The low boron carnallite is step（3）It is classified the underflow obtained by boron removal.
Further, in each step, washing mother liquor is step（7）It is produced.The purpose is to by step（7）In it is caused low
The high potassium washing mother liquor of magnesium passes through step（5）The low potassium decomposition nut liquid of high magnesium is converted into, reclaims the K in mother liquor+, a whole set of work is improved with this
The K of skill+The rate of recovery.Further, can K by mass percentage when whole set process does not have washing Recycling Mother Solution in the first round+
3.382%、Na+4.326%、Mg2+3.423%、Cl-16.23%、SO4 2-4.734%th, Yu Weishui composition is prepared.
（6）Flotation：Toward step（5）In gained solid-liquid mixed ore pulp add flotation collector using one thick one it is single-minded sweep, essence
Ore deposit and scavenger concentrate is chosen to return to the closed circuit floatation process acquisition KCl flotation concentrates of roughing.
The flotation collector is mixing-in fat amine, is lauryl amine, octadecylamine in mass ratio 1：3~5（It is preferred that 1：4）It is multiple
Match somebody with somebody.Dosage is 80~120g/t solid-liquid mixed ore pulps.
（7）Wash drying：By step（6）Gained flotation concentrate and water in mass ratio 1: 0.10~0.15 are mixed, and room temperature is stirred
20~40min is mixed, after filtering, it is KCl products that solid phase, which is dried,；Liquid phase is to wash mother liquor, return to step（5）Decompose low boron light
Halogen stone ore.
By above step, the KCl products for meeting national standard Grade A requirement can be obtained.
Present invention process aims to solve the problem that the technical barrier using high boron carnallite raw ore production KCl, this method novelty
Add alkali metal phosphate and disperse alkali formula antifungin calcium compound, only needed after sizing mixing by common desliming device desliming bucket removing
Superfine alkali formula antifungin calcium compound particle, solves existing acid adding except the cost of boron technique is high and problem of environmental pollution.The present invention
Technological process is simple, easy to operate, the main useful element K in raw ore+The rate of recovery is high, and resource utilization is high, is avoided that resource wave
Take, new thinking is provided except boron produces KCl products for the carnallite of this type.
