Description
Technical field
The present invention relates to the floatation separating technology field of mineral, specifically, relate to a kind of from low grade potassium albite
The method that quartz is separated in ore deposit.
Background technology
China's feldspar resource is a lot, and distribution is also very extensive, but the impure more, quality of larger a part of feldspar ore is not
Height, as the high-quality feldspar ore raw material in China is increasingly reduced, and the industry such as ceramics is fast to the demand of feldspar, particularly high-quality feldspar
Under the background that speed increases, it is extremely urgent that feldspar fine powder is purified from low-quality feldspar ore.At present, from low-quality potassium albite
Purify potassium albite fine powder and mainly carry out combined sorting operation using ore dressing means such as gravity treatment, electric separation, magnetic separation, flotation, so as to reach
To iron, titanium, quartz, the association gangue mineral such as mica removed in potassium albite ore, reach feldspar essence of the recovery rich in potassium, sodium
Purpose ore deposit.Wherein, in the prior art, quartz is separated from potassium albite ore using method for floating and mainly uses highly acid method, this
One technique needs highly acid as flotation medium, causes that workshop tart flavour is very big, and equipment corrosion is serious, to employee's health
Infringement is greatly and peracidity abandoned mine slurry can also produce serious pollution to environment.
In addition, the means of generally use direct flotation separate quartz from potassium albite ore in the prior art, i.e., direct flotation floats
Play feldspar, suppress quartz, what it is through collecting agent seizure is the mineral grain rich in potassium albite.Due to feldspar content in potassium albite
Greatly, quartz content is few, and direct flotation " it is few will to float more suppressions ", so No. 2 oil of the foaming agent used under acid condition in direct floatation process
40-60g/ tons are needed, activator petroleum sodium sulfonate needs 600-1000g/ tons, and collecting agent lauryl amine wants 300-600g/t, each floating
Select reagent consumption amount larger, cause production cost higher, constrain the development of industry.On the other hand, largely using mahogany acid
Sodium can also cause feldspar fine powder appearance color burnt hair, influence product appearance condition and in later stage feldspar fine powder high temperature production frit
Environment can be polluted.
In order to solve the above problems, people are seeking a kind of preferable technical solution always.
The content of the invention
The purpose of the present invention is in view of the shortcomings of the prior art, to be separated so as to provide one kind from low grade potassium albite ore
The method of quartz, to solve the above problems.
The technical solution adopted in the present invention is：A kind of method that quartz is separated in the albite ore from low grade potassium, specifically
Comprise the following steps：
（1）A kind of low grade potassium albite miberal powder is provided；
（2）The low grade potassium albite miberal powder and water are carried out being mixed to get low grade potassium albite ore slurry, used
The pH that conditioning agent adjusts the low grade potassium albite ore slurry is 8~10；
（3）First to the low grade potassium albite ore slurry carry out at least once roughing handle, obtain roughing slurry and
Scan ore pulp；Then processing is scanned at least once to the ore pulp of scanning, obtains scanning mine tailing feldspar slurry；It is last described
Roughing slurry and to it is described scan mine tailing feldspar slurry carry out selected processing at least once, floatingly select quartz, obtain potassium albite
Fine powder is starched；Wherein, each roughing, scan every time during be both needed to add activator, inhibitor and amine collector, and each medicament
Addition be added in the low grade potassium albite miberal powder per ton 10g~100g the activator, 20g~60g it is described
The amine collector of inhibitor and 30g~300g；
（4）Processing is dried to potassium albite fine powder slurry, obtains potassium albite fine powder.
Based on above-mentioned, there is provided include the step of a kind of low grade potassium albite miberal powder：It is former to low grade potassium albite first
Ore deposit is crushed, and the low grade potassium albite grain graininess after control is broken is less than 10mm, realizes the mesh of more broken, few ore grindings
's；Then processing is ground to the low grade potassium albite particle and obtains low grade potassium albite original ore powder；Finally to institute
State low grade potassium albite original ore powder and carry out desliming, magnetic separation processing respectively so that in the low grade potassium albite original ore powder
Thin mud, iron oxide and iron content mica group impurity are removed, so as to obtain low grade potassium albite miberal powder.Wherein, the low product
Position potassium albite raw ore refers to SiO in potassium albite tcrude ore2Content be more than 70%, Al2O3Content be less than 17% and raw ore in
The coloring oxide Fe that mass percent is more than 0.2% be present2O3Deng.
Based on above-mentioned, the activator is alkaline-earth metal ions activator or one kind in nonionic surfactant or two
The mixing of person.
Based on above-mentioned, the alkaline-earth metal ions activator is calcium chloride, lime or barium chloride.
Based on above-mentioned, the nonionic surfactant is polyoxyethylene, polyacrylamide or aliphatic acid polyethenoxy alcohol.
Based on above-mentioned, the inhibitor is one or more of in dodecyl sodium sulfate, waterglass, calgon
Mixing.
Based on above-mentioned, the amine collector is one or more of mixing in lauryl amine, octadecylamine, ether amines.
Based on above-mentioned, the conditioning agent is the mixing of one or both of sodium carbonate, sodium hydroxide.
The present invention is adjusted described low-grade in the method that quartz is separated from low grade potassium albite ore using conditioning agent
The pH of potassium albite ore slurry is 8~10, forms a kind of alkaline system, effectively reduces the low grade potassium albite ore slurry
In each ore particles surface oxidation current potential so that rich in potassium albite particle be prone to surface oxidation generation hydrophily thing
Matter；On the other hand, the activator of addition can cause the surface contact angle rich in quartz particles to increase, and increase its surface hydrophobic
Greatly, floatability improves.
Simultaneously the material such as the waterglass in inhibitor, calgon can with the substance reaction such as the calcium chloride in activator,
Generation gel-like substance can be preferentially adsorbed on is rich in potassium albite particle surface with hydrophilic, causes its floatability further
Reduce.Meanwhile the material such as dodecyl sodium sulfate in the collecting agent of addition in the material and inhibitor such as lauryl amine can rich in
The surface of quartz particles produces physical absorption and hydrogen bond action, and is inhaled only existing physics rich in potassium albite particle surface
It is attached, increase the difference of swimming rich in quartz particles and rich in both potassium albite particles so that preferentially obtain rich in quartz particles
Flotation, and then realize and isolate quartz from low grade potassium albite ore.
The present invention is compared with the prior art with prominent substantive distinguishing features and significantly progressive, and specifically, the present invention carries
It is reverse flotation to floatingly selecting less quartz in potassium albite ore in the basic conditions that the separation method of confession, which is, in floatation process,
Because each floating agent consumption is less and alkaline not high, low is required to equipment anticorrosion, therefore low production cost, environmental pollution
It is few, and obtained potassium albite fine powder reaches ceramic industry and uses standard GB/T9195-1999.
Embodiment
Below by embodiment, technical scheme is described in further detail.
Embodiment 1
The present embodiment is using Guangxi Wuzhou area low grade potassium albite raw ore as raw material, the low grade potassium albite after measured
The mass percent of main matter is as shown in table 1 in raw ore, and the present embodiment utilizes technology provided by the invention, from Guangxi Chinese parasol tree
Quartz is separated in the low grade potassium albite raw ore of state area, obtained satisfaction reaches potassium albite essence of the ceramic industry using standard
Powder.
