Wet type Electromagnetic Separator 

Acid immersion is the use of quartz insoluble in acid (except HF), other impurity minerals can be dissolved by acid liquid characteristics, so as to achieve the further purification of quartz by PTMS Electromagnetic Separator. Acid immersion commonly used acid sulfuric acid, hydrochloric acid, nitric acid and hydrofluoric acid, reducing agent sulfituric acid and its salts. Acid can have good removal effect on non-metallic impurity minerals in quartz,

PTMS Electromagnetic Separator

On different metal impurities, the species and the concentration of acid are relatively significant. It is generally believed that various dilute acids have significant effects on the PTMS Electromagnetic Separator removal of Fe and Al, while the removal effect of Ti and Cr is treated by acid leaching with concentrated sulfuric acid, royal water or HF. A mixed acid composed of acids is usually used for the acid extraction of impurity minerals. Considering the dissolution effect of HF on quartz, the HF concentration generally does not exceed 10%.

what is magnetic separation in science?

In addition to the concentration of acid, the amount of acid, acid leaching time, temperature and slurry stirring can affect the quartz acid immersion effect. The control of various factors should be according to the final grade requirements of quartz, try to reduce the concentration, temperature and dosage of acid, reduce the acid immersion time, so as to achieve PTMS Electromagnetic Separator quartz purification at a lower dressing cost.
