high gradient magnetic separation

Using quartz insoluble in acid (except HF), containing Fe impurity minerals can be dissolved by acid liquid characteristics, commonly used acid is sulfuric acid, hydrochloric acid, nitric acid and hydrofluoric acid, can be divided into cold acid immersion method and hot acid immersion method. In the process of acid immersion, acid can form a complex with impurity ions and then dissolve in water to achieve the effect of PTMS MAGNETIC SEPARATOR purification. The commonly used acids are oxalic acid and acetic acid.

PTMS Electromagnetic Separator

PTMS MAGNETIC SEPARATOR The mixed acid immersion method is to mix different acids to remove all kinds of impurities in quartz sand. the removal efficiency is higher, and the product purity is better, because the harmful components in quartz sand often exist in mineral aggregate rather than single mineral form, so the mixed acid immersion effect is better. But the cost of using these acids is high and has a great impact on the environment.

what is magnetic separation method for concentration of ore ?

PTMS MAGNETIC SEPARATOR Using oxalic acid as an extraction agent to remove iron impurities in quartz sand. When the average particle size of quartz sand is 20um, the Fe2O3 content in quartz sand can be reduced from 110ppm to 10ppm, and the iron removal rate can reach more than 80-90%.
