drum separator

Chemical treatment is mainly treated with inorganic acid or reducing agent, which is suitable for obtaining high purification effect of PTMS MAGNETIC SEPARATOR. Pickling and pickling are common chemical treatments. Acid leaching method can be divided into cold acid leaching method and hot acid leaching method, commonly used acids are hydrochloric acid, sulfuric acid and hydrofluoric acid, these acids have a good removal effect on the metal impurities in quartz sand, especially the removal effect of Fe and Al is obvious.

PTMS Electromagnetic Separator

The main factors affecting the purification effect of acid leaching PTMS MAGNETIC SEPARATOR are acid composition, acid concentration and dosage, temperature and time. After acid leaching, high purity quartz sand with a purity of 99.99% or even ultra-high purity quartz sand can be obtained. Complex method is the use of quartz sand in the acid leaching process, acid can form a complex with impurity ions and then dissolve in water, so as to achieve purification effect.

what is magnetic separation in chemistry ?

The main acids commonly used in complexation are oxalic acid and acetic acid. It has been reported that the use of oxalic acid as a leaching agent to remove iron impurities in quartz sand, the content of Fe2O3 in quartz sand is reduced from 110ppm to 10ppm, and the iron removal rate reaches more than 80-90%, but PTMS MAGNETIC SEPARATOR has certain requirements for the particle size of quartz sand (average particle size 20um).
