Quartz sand is insoluble in acid (except hydrogen fluoride), and iron impurity minerals can be dissolved by acid, based on this feature, acid leaching can effectively remove iron impurities from quartz sand. In addition, it can also remove non-metallic impurities in use. PTMS magnetic separator Common acids are sulfuric acid, hydrochloric acid, nitric acid and hydrofluoric acid.

PTMS magnetic separation

 
Generally, the harmful components in quartz sand are in the form of mineral aggregates, and the single acid leaching effect is not good, so the mixed acid leaching method is mostly used by PTMS magnetic separator. This method can make the final product meet the quality requirements of float glass for high quality silica sand, and the quality is good and the yield is large.

what is magnetic separation in Kaolin?

 
It should be noted that the ratio of various acids, adding sequence, temperature, acid leaching time, mineral particle size and pulp mixing uniformity will have a great impact on the removal of impurity minerals. PTMS magnetic separator There are two kinds of scrubbing methods, one is mechanical scrubbing method, the other is rod friction scrubbing method.
