magnetic separator supplier

The method of PTMS magnetic separator flotation for iron removal of quartz sand is hydrofluoric acid as activator and amine cationic collector is used for flotation under strong acidic condition (pH2 ~ 3). Quartz activated by metal ions can be inhibited by NaOH in iron flotation. The methods can be divided into fluorine-acid method, fluorine-acid method and fluorine-acid method.

PTMS magnetic separation

 
Fluorine-acid method: This method is easy to control, PTMS magnetic separator flotation effect is good, flotation index is relatively stable, but the presence of fluoride ions, caused great damage to the surrounding land and environment.
Non-fluoridated acid method: The production index of this method is stable and has no harm to the surrounding land and the environment. However, due to strong acid and strong corrosion, it has higher requirements for PTMS magnetic separator.

what is magnetic separation method in hindi？

Fluorine-free acid-free method: This method is to create a unique high-concentration pulp flotation environment under natural pH conditions through the reasonable allocation of cationic and anion collectors, to achieve the purpose of preferential flotation of impurity minerals. However, PTMS magnetic separator method has higher requirements on raw sand treatment and pulp environment.
