PTMS magnetic separation

what is magnetic separation ？

Purification process
The quality of quartz sand raw materials in the industry is getting lower and lower. In order to meet the industrial needs, the grade can be improved through the beneficiation process. There are mainly the following purification methods:
1, rub the mud
Scrubbing refers to the removal of thin film iron, bonding and muddy impurity minerals on the surface of quartz sand by mechanical force and the frictional force between sand grains, and further shredding the unassembled mineral aggregates, and further purification of quartz sand by classification operation. Effect. Today there are mainly rod scrubs and mechanical scrubs. The main factors affecting the scrubbing effect are the structural characteristics and configuration of the scrubber; the secondary factors are scrubbing time and scrubbing concentration (the scrubbing concentration is generally 50%-60%). There are mainly mechanical scrubbing, rod scrubbing and dosing, high-efficiency strong scrubbing and ultrasonic scrubbing.
2, magnetic separation
Magnetic separation is mainly used to remove magnetic minerals in quartz sand. For example, weak magnetic minerals such as hematite, limonite and biotite can be removed by a strong magnetic machine, while ferromagnetic minerals such as magnetite can pass weak magnetic separator. Remove.
3. Flotation
Flotation is used to remove impurities such as feldspar and mica in quartz sand that cannot be removed by magnetic separation, further improving the purity.
4, acid leaching
Acid leaching is the use of quartz insoluble in acid (except HF acid), while other impurity minerals can be dissolved by acid, which can further purify quartz.
5, microbial leaching
It refers to the use of microorganisms to extract the thin film iron or dip-dyed iron on the surface of quartz sand particles. This is a newly developed iron removal technology.
Production Process
1. Large stone enters the warehouse
2, choose rough
3, choose fine broken
4, sand machine vibration screening
5, the sand washing machine washes out the finished sand
6, dryer drying or natural drying
