Potassium feldspar is widely used in ceramics, glass, electrical porcelain, abrasive materials and potash fertilizer industries. As demand grows, the industrial value of potassium feldspar is getting higher and higher. Therefore, it is very important to remove impurities, especially iron, during processing.
Application of potassium feldspar
Potassium feldspar is extensively used in the production of ceramic bodies, glazes, fire-resistant calcium silicate boards, glass and enamel industries, abrasive materials, etc. Its aesthetically pleasing colors make it a popular choice for decorative stones and semi-precious gems. Additionally, high-quality potash feldspar is utilized in the manufacturing of TV display glasses and can also be used to produce potash fertilizers.
The Process of Deironing and Beneficiation of Potassium Feldspar
Process of impurity removal
Photoelectric sorting
Use photoelectric sorting machine to separate raw ore, remove waste rock and impurities, and improve sorting efficiency.
Magnetic separation
Remove weak magnetic impurities in feldspar, such as iron minerals, biotite, etc.
Flotation process
Remove ferrite-containing minerals, such as pyrite, mica, etc.
The Process flow of Beneficiation equipment
Crushing
The raw ore is first crushed by a jaw crusher. It then moves to a cone crusher on a belt conveyor for more crushing.
Sorting
After secondary crushing, potassium feldspar particles are screened. They are sent to a sorting machine for further classification. Waste rock is thrown away.
Grinding
The concentrate waste is ground. The resulting potassium feldspar powder is sorted in a spiral classifier.
Magnetic separation
The fine-ground potassium feldspar powder goes through magnetic separation. Strong magnets remove iron and mica.
Flotation
Feldspar flotation removes iron and titanium. It also separates quartz and other materials. Different methods are used depending on the feldspar's condition.
Dewatering and drying
After separation, the feldspar is dewatered in a concentrator. It then goes to a dryer for quick drying. The dried powder is the final product.
Introduction to Feldapsr Processing Equipment
The equipment required for the potassium feldspar mineral processing process includes a jaw crusher, cone crusher, grinding machine, vibrating feeder, spiral classifier, ore color separator, artificial intelligence separator, magnetic separator, flotation machine, dryer, vibrating screen and conveyor. Depending on the different forms of potassium feldspar present variations in the necessary equipment may occur.
