K-Na-Feldspar Iron Removal Equipment of Magnetic Separator 

Potassium albite is an important raw material for glass, ceramics and electronic industry. Iron ore, biotite, amphibole and tourmaline in potassium albite have certain magnetism, so it can be separated from potassium albite under the action of external magnetic field. Generally, the magnetic properties of these minerals in K-Na feldspar are weak, and only by using high-intensity magnetic separation equipment can a better separation effect be obtained.

Quartz, the main mineral in quartz sand, is a diamagnetic material and cannot be magnetized in magnetic field. The iron-bearing impurity minerals in quartz sand, such as hematite, limonite, magnetite and goethite, are mostly magnetic materials, which can be magnetized in the magnetic field. In magnetic separation process, these iron-bearing impurity minerals in quartz sand are removed by magnetic separation, taking advantage of this difference in nature. The more magnetic separation times, the better iron removal effect.
