Feldspar magnetic separator

Feldspar is a common rock-forming mineral, which is widely found in various magmatic rocks and metamorphic rocks, accounting for about 50% of the total weight of the earth's crust. When feldspar is fairly enriched, it constitutes an industrial mineral. Under low temperature hydrothermal action or surface environment, feldspar is often transformed into clay minerals. According to the composition, feldspar can be divided into 4 categories: potassium feldspar, albite, anorthite and barium feldspar. The most common in industrial applications are albite and potash feldspar. These two types of feldspar materials are mostly used in ceramics and other fields after ore beneficiation purification or iron removal purification. The beneficiation process is feldspar deferromagnetism. Choose machine.


The main purpose of the processing of feldspar materials by feldspar magnetic separator is to remove iron and impurity. The impurities are mainly iron-containing minerals. Among them, ferric oxide and ferro-titanium are the main components of iron-containing impurities. After beneficiation and purification, the finished feldspars can meet the market's whiteness requirements for ceramic products.

Types of feldspar magnetic separator

 

1.Dry magnetic separator

This kind of feldspar magnetic separator is more suitable for the removal of iron from feldspar with coarse-grained iron minerals, and does not use water for beneficiation;

2.Wet magnetic separator

This type of feldspar magnetic separator is more useful for iron-containing magnetic minerals in feldspars, which are mostly dispersed in feldspar minerals with fine particles embedded to form inclusions of magnetic minerals for iron removal purification operations.

Which of the above two types of feldspar magnetic separators is better, may be more effective after the wet magnetic separator finely grinds feldspar minerals. The wet feldspar magnetic separator When used for iron removal operations, after two to three magnetic separation operations, the iron content in feldspar can be reduced to less than 0.1 under good magnetic separation operation conditions. Of course, which type of feldspar magnetic separator to choose depends on the distribution of feldspar minerals processed by the user.

Feldspar iron removal production line process

Generally, the iron minerals contained in feldspar are all magnetic minerals. Except for a small amount of magnetite, which has strong magnetic properties, most of the components of iron trioxide and ilmenite are weakly magnetic, so the entire feldspar iron removal production line process The magnetic separation process is mostly used, and the iron removal process is basically a "weak magnetic + strong magnetic" process.
