China's potassium feldspar rich resources are few, and often coexist with other impurity minerals, especially a small number of impurities such as iron and titanium, which affect its quality and application, so it needs impurity removal. At present, the main impurity removal methods of potassium feldspar are magnetic separation, flotation separation, acid leaching process and combined process. Specifically, the appropriate impurity removal process should be selected according to the occurrence state of impurity minerals and the embedded particle size.

For weak magnetic minerals such as iron oxide, mica and garnet in potassium feldspar ore, strongmagnetic separationshould be used for separation, and the choice of magnetic separation equipment needs to be determined according to the property of the ore. Commonly used magnetic separation equipment includes the wet cylinder magnetic separator, the vertical ring pulsating high gradient magnetic separator, the flat magnetic separator.

In actual production, the magnetic separation effect of potassium feldspar ore impurity removal is mainly affected by the magnetic field strength of magnetic separation equipment and the number of magnetic separations.

When the iron-containing impurities in potassium feldspar are pyrite, mica or in the form of iron-containing alkali metal silicate minerals such as garnet, tourmaline and hornblende, theflotationmethod is mostly used to remove the impurities. The conditions for removing potassium feldspar impurities by flotation are as follows:

It is worth noting that weakly acidic flotation has a lower dosage of flotation reagents than weakly alkaline flotation. The output of potash feldspar is high, and the flotation effect is better. Whengrinding, its recommended to prevent insufficient kinetic energy of particles by over-grinding, and the bubbles interacting with the ore particles cannot break through the surrounding hydration layer, making the target minerals difficult to separate.

The acid leaching process is a method of removing iron from potassium feldspar by using acids to selectively dissolve the iron-containing minerals. It is an effective method to process potassium feldspar containing very fine embedded crystal structure impurities.

5. Oxalic acid has strong acidity, stronger reducibility than other inorganic acids, and has a good complexing ability. It is currently an effective organic acid for dissolving iron oxides which are widely used in removing iron from potassium feldspar, and dissolves hematite slowly, but iron hydroxides such as needle iron ore and fibrous iron ore are easily dissolved, and the iron removal rate can reach 90%.

For some difficult to select potassium feldspar ore, not only the iron content is high, but also some of the impurities penetrate into the cleavage gap of potassium feldspar in the form of iron staining. When a single separation process cannot meet the requirements of the concentrate, it is appropriate to use the combined impurity removal process, such as acid leaching-flotation combined process, flotation-magnetic separation combined process, scrubbing-magnetic separation-flotation combined process, desliming-strong magnetic-acid leaching combined process, etc.

Taking the removal of iron from the combined acid leaching and flotation process as an example, it uses sulfuric acid to remove most of the iron minerals in the ore. The product after acid leaching is used as the raw material for flotation, and sodium oleate is used as a collector for flotation to separate a small amount of iron staining compounds. The whiteness of potassium feldspar is obviously improved, and the iron removal effect is good.

In short, among the above four potassium feldspar impurity mineral removal processes, the magnetic separation removal process is more environmentally friendly, easy to operate, and is one of the important potassium feldspar removal process to remove impurities. For potassium feldspar with non-magnetic impurities, it is advisable to adopt the flotation removal process, and pay attention to choosing a reasonable flotation reagent system and operating parameters at the same time. For the potassium feldspar containing microfine particles or hard-to-select impurities in the form of iron staining, it is appropriate to adopt the acid leaching process or combined impurity removal process.

Whats the workflow of the feldspar stone processing plant? Generally speaking, the feldspar concentrate rich in potassium and sodium is recovered by the combined mineral separation methods of gravity separation, electric separation, magnetic separation and flotation to remove associated minerals such as quartz and mica.

The crushing and grinding of feldspar are not only to meet the grain size requirement of the final product, but also to meet the need of the impurity removal process. The coarse crushing of feldspar mostly adopts jaw crusher, and the particle size is about 10mm. There are many options for fine crushing and grinding machines of the feldspar processing plant, mainly roller crusher, impact crusher, sand making machine, hammer crusher, stone grinding, column mill, tower mill, Raymond mill, stirring mill, vibration mill, sanding mill, and airflow mill, etc. At present, feldspar grinding can be divided into dry grinding and wet grinding, wet type grinding is more efficient than dry type.

From the point of view of the application industry, the processing of feldspar raw materials in the glass industry mostly adopts a steel rod medium grinding machine, which has high grinding efficiency and uniform particle size, but the introduction of iron pollution leads to the low quality of feldspar products. The ceramic industry has higher requirements for feldspar raw materials, so stone roll grinding or ceramic ball grinding is often used, which has low grinding efficiency and high energy consumption, and can not realize high efficiency and continuous process.

On the basis of ensuring the high quality of feldspar products, how to realizing high efficiency grinding process and continuous production is an important subject in the research of feldspar beneficiation and purification.

The washing process is suitable for feldspar produced from weathered granite or feldspar placer, which mainly to remove impurities such as clay, fine mud and mica. On the one hand, it can reduce the content of Fe2O3 in feldspar ore, on the other hand, it can increase the content of potassium and sodium in feldspar ore. Common ore washing machines: Denver washer dryer, vibrating screen, log washer, mixing tank, and grinders.

Desliming is mainly used to remove the primary slime and the secondary slime produced by grinding, prevent a large amount of fine slime from affecting the separation effect of subsequent operations such as flotation and magnetic separation. Commonly used equipment desliming hopper, centrifuge concentrator, hydrocyclone, etc.

Due to the magnetic properties of iron minerals, mica and garnet in feldspar ore, it can be separated from feldspar mineral by the external magnetic field. In general, the magnetic properties of iron minerals and mica in feldspar are weak, only by using high-intensity magnetic separator can get a good result. The main magnetic separator equipment has a permanent magnetic roller type strong magnetic separator, permanent magnetic drum type medium strong magnetic separator, wet flat type strong magnetic separator and high gradient strong magnetic separator.

Flotation is an effective way to remove impurities in feldspar. On the one hand, the impurity elements such as iron and titanium can be removed from feldspar, the combination of chemical agents depends on the existing components of impurity; on the other hand, the feldspar can be separated out the quartz, thus increase the content of K, Na. At present, there are many studies on the separation of feldspar and quartz, as well as the selective separation of potassium feldspar and albite.

It is difficult to remove the iron-bearing minerals in ultrafine feldspar particles by traditional methods, but leaching can achieve better results. The feldspar leaching reagent is not only beneficial to the decomposition of feldspar, but also can effectively remove the interlayer iron minerals on the surface of feldspar. Biological leaching has the advantages of simple operation and low environmental pollution.

For some very difficult separating feldspar, of which iron content is high, some iron minerals are permeated in the feldspar cleavage, only single separation process does not meet the requirements of concentrate, the combination of multistage is introduced at the right moment.

(1) Magnetic-floating combined flow Most of the iron minerals were removed by magnetic separation, and then the fine iron minerals and iron-stained Potassium Feldspar were removed by flotation. Dry magnetic separation followed by flotation can get the best separation effect, but the dry magnetic separation need dehydration and drying process, the cost is higher, so wet magnetic separation followed by flotation process is more widely used. (2) Stripping-strong magnetic separation process combined flow If the feldspar ore is soft, easy crushing, put them into the grinding mill machine to peel off the iron material in the mica group minerals. The result shows that the stripping-strong magnetic separation process has a significant improvement, besides, its cost is lower than that of the magnetic flotation combined flow.

Potash feldspar belongs to the feldspar family of minerals. According to its density, hardness, and the components and characteristics contained, it is widely used in glass, electric porcelain and other industrial manufacturing and potassium fertilizer. In addition, potassium feldspar can be ground into ultra-fine white ash powder, which can be used in construction, agriculture, industry, rubber, metallurgy and some high-tech industries.

Potash feldspar has high density, hardness, and silica content, which would cause serious wear on the crusher parts like the plate, hammer, chamber. Therefore, in the design of the potash feldspar crushing process, the crushing machine of the lamination principle is used as much as possible to reduce the wear of the wear-resistant parts. Potash feldspar crushers include jaw crusher, cone crusher, and impact crusher.

The raw materials are fed into the silo via a dump truck, and the materials are evenly fed into the jaw crusher through a vibrating feeder to prevent the material from impacting the crushing cavity to cause damage to the equipment. At the same time, the situation of overloaded stuffy cars is avoided. The jaw crusher performs initial crushing, crushing the material to a particle size of about 250mm, and then uniformly feeding the crushed material into the cone crusher through a belt conveyor for secondary crushing. The vibrating screen is used for sieving and grading. Materials larger than 31.5mm are returned to the cone crusher for further crushing. Materials below 31.5mm are divided into 0-10mm and 10-30mm materials by the belt conveyor to the finished product pile.

Potassium feldspar raw material is sent into the raw material warehouse by the forklift or dump truck, and then evenly fed into the jaw crusher by the vibrating feeder, crushing the material to the size of about 150mm, and then sent to the cone crusher for the second crushing. The crushed material is classified by a vibrating screen, and the 0-5mm material is sent to the finished product pile by a belt conveyor. The material> 30mm is sent by the belt conveyor to the cone crusher and then broken by the vibrating screen to form a closed circuit. 5-30mm material is sent to the high-efficiency centrifugal impact sand making machine through a belt conveyor for crushing. The crushed material is classified by a vibrating screen, and 0-5mm material is sent to the finished product pile by a belt conveyor. The material is again sent to the high-efficiency centrifugal impact sand making machine to be broken, forming a closed circuit, until the material meets the specifications of the finished product, and then sent to the finished product pile.
