Potash feldspar is a monoclinic system, usually with reddish yellow and white color. Widely used in ceramic blanks, ceramic glazes, glass, porcelain, abrasives and other industrial sectors and the use of potash fertilizer. In recent years, the way of potash feldspar to develop potassium has matured, and the extracted potassium has gradually been put into use. This is very good for our country and even the world. So, how much is a metric ton of potash feldspar ? It should be noted that the process for the development of potash feldspar is not very simple. On the contrary, the production process needs to be very careful, so if you want to develop potash feldspar efficiently, you need to have a good understanding of its production. Process and how much a pot of feldspar potassium .
What is K-feldspar
Feldspar is an aluminosilicate mineral containing some alkali metals. It is also called the feldspar mineral. Potash feldspar belongs to this kind of feldspar mineral, according to its density, hardness, and the ingredients it contains. Characteristics, but is widely used in some glass, electric porcelain and other industrial manufacturing and the use of potash fertilizer.
Potash feldspar use
Glass flux
Because K-feldspar is the main ingredient in the production of glass mixes, and the use of potash feldspar in the use of iron is relatively low, and easier than aluminum oxide melt, relatively speaking, the melting temperature of potassium feldspar is low The wide range, so it is often used to increase the alumina content in the glass ingredients, thereby reducing the amount of alkali in the glass production process. In addition, potassium feldspar can also be used to adjust the viscosity of glass materials.
2. Ceramic body ingredients
When potassium feldspar is used as a ceramic green body, the shrinkage or deformation of the green body due to drying can be reduced, thereby improving the drying performance and shortening the drying time of the ceramic. In addition, potassium feldspar can be used as a flux to reduce the temperature during the firing process. At the same time, it can also make the compact between the blanks to reduce the gap and increase the transparency of the ceramic blank.
3. Other raw materials
In addition to the above uses, potash feldspar is also a major component of ceramic glazes, and the most important one in the ceramic industry is potassium feldspar. In addition, potash feldspar can also be compared with other mineral raw materials for blending, and is also a kind of enamel raw material most commonly used in painting. The rich potassium contained in potassium feldspar can also be extracted as a raw material for potash fertilizer.
In addition, potassium feldspar can also be ground into ultra-fine white ash powder, which is also a raw material commonly used in industry. The ground powder can be used in construction, agriculture, industry, etc., if it is fine White powder can be used in rubber, smelting, and some high-tech industries.
How much is a pot of potassium feldspar
The price of one ton of potash feldspar ranges from 180 to 500 yuan. It is suggested that before buying, you may wish to visit the store first. Shop around, depending on your actual situation.
Note: This price is for reference only! Due to geographical differences, of course, the price will be different. For more details on the prices, please refer to the local distributors!
Potassium feldspar process
Flotation iron removal: Before you begin to develop potash feldspar, you should know that the content of potash feldspar contains not only richer potassium but also a certain amount of iron, while iron is a more active element. In order to ensure that potassium feldspar is not affected by iron during the development process, iron removal work must be done. In general, the iron content should be reduced to about 0.039%, and the commonly used methods are low-temperature decomposition or hydrothermal method. Of course, depending on the reaction before the element, iron can be separated by adding appropriate reagents.
Flotation Feldspar: The first step to be taken at this time is to continue to grind the raw ore that was mined. During this step it is necessary to pay attention to the thickness of the sand. Generally, do not polish too much so as not to damage the structure of the feldspar. After the grinding work is completed, the ore washing operation can be performed. When the washing is performed, the mud removal process is performed, and then rough selection is performed. However, certain iron removal work is also performed when the rough selection is performed. The iron removal work here is almost the same as the flotation iron removal work. The same method can also be used. Of course, a method of adding a regulator or a collector can also be used. The potassium feldspars left after this round of iron removal work are subject to rough selection before they can proceed to the next step. The last remaining potassium feldspar is the feldspar concentrate, and the ore that is removed is the tailings. In general, feldspar concentrates are commonly used for deep processing.
Dehydration treatment: After the ore has been graded, it will be dehydrated. In this step, it is generally recommended to use a turbine or a porcelain ball mill. This will improve the working efficiency and ensure the quality of the ore. . After the completion of this step, the basic process of potash feldspar is completed, after which only a certain degree of protection is required.
K-feldspar demand status
Potassium feldspar in the ceramic industry as a ceramic body ingredients, ceramic glaze accounted for 30% of the amount, and the rest for chemical, glass flux, enamel raw materials, abrasives, glass fiber, welding rods and other industries. With the economic development, the use of glass products, building ceramics and other increasingly large quantities, the increasing demand for potassium feldspar, the market prospects are broad.
With the vigorous development of the ceramic industry, the heavy consumption of potash feldspar resources has caused the reserves of potash feldspar to continue to decrease, and the cost of mining is increasing. Therefore, it is inevitable that the price of potash feldspar will rise. Domestic supply of high-quality potassium feldspar is in short supply. At present, high-quality potassium feldspar resources used in the ceramic industry are imported from North Korea, India, and other countries.
From the perspective of the nature of China's potash feldspar companies, the current mining operators of potassium feldspar are mainly private enterprises. The distribution of China's potassium feldspar is scattered, the mining conditions are poor, the starting point is low, and the relative risk is relatively small. The K-feldspar industry has a low concentration, a large number of companies, a small scale, and a serious waste of resources.
Editor's summary: In general, the process of potash feldspar is still quite complicated, and the matters needing attention are also relatively more, so we must be more careful in the development process, always pay attention to the changes of potassium feldspar, has reached the most Good results.
