high gradient magnetic separation

The fundamental principle of PTMS MAGNETIC SEPARATION lies in progressively enhancing quartz sand purity through tailored treatment methods based on the physical and chemical properties of different impurities. Taking the typical integrated purification process combining flotation, acid washing, chlorination roasting, and PTMS MAGNETIC SEPARATION as an example: The flotation stage utilizes mineral surface physicochemical differences for separation.

PTMS magnetic separation

In quartz sand, different mineral particles exhibit distinct surface properties. By adding appropriate flotation reagents, these quartz particles can display distinct flotation behaviors compared to impurities in the flotation cell. Mineral particles containing iron, aluminum, and other impurities tend to adhere to bubbles and be carried to the cell's surface, where they separate from quartz particles. This separation facilitates the iron removal process in the PTMS MAGNETIC SEPARATION system.

This process effectively removes floating impurities from quartz sand, establishing the foundation for subsequent PTMS MAGNETIC SEPARATION purification. The acid washing stage then utilizes strong acids like hydrochloric or sulfuric to dissolve metal oxide contaminants. Common impurities such as iron and aluminum oxides in quartz sand can compromise purity and quality, necessitating the PTMS MAGNETIC SEPARATION iron removal process.
