Process Introduction:
Feldspar mainly contains iron minerals, and its impurities include clay, quartz, mica, garnet, beryl and so on. Generally, magnetic separation, gravity separation, flotation and combined process are used for separation.
According to the types of feldspar deposits and ore properties, customize the appropriate feldspar mining process and equipment, and recover high-quality feldspar concentrate.
Feldspar is an aluminosilicate mineral containing calcium, sodium, and potassium. There are many kinds of it, such as orthoclase (potassium feldspar), albite, anorthite, micro plagioclase, sanidine, etc. The feldspar beneficiation process is mainly magnetic and flotation separation for mineral processing.
1. Ore Washing: Mainly to remove impurities such as clay, fine mud, and mica in potassium feldspar, reduce the content of ferric oxide in potassium feldspar, and increase the content of potassium and sodium. Suitable for separation of weathered granite or feldspar placer.
2. Crushing & Screening: Feldspar coarse crusher and fine crushing are generally used, and vibrating screen screening ensures the qualification of the ore particle size entering the next stage of the process.
3. Grinding & classifying: Generally, one-stage or two-stage grinding is used to grind ore economically to any particle size required for mineral processing. According to the requirements of technology and feldspar properties, grinding can be divided into dry grinding and wet grinding.
4. Separation stage: According to the nature of the ore, select the appropriate beneficiation process.
