kaolin clay magnet requirements

Scrubbing is to remove the film iron and mud impurity minerals on the surface of quartz sand with the help of mechanical force and the grinding force between the sand particles and further wipe the unmonomer mineral aggregate, and then achieve the effect of further purification of quartz sand by PTMS magnetic separator separator. At present, there are mainly two methods: rod friction washing and mechanical scrubbing.

PTMS magnetic separator

 
The separation of mica and quartz is very difficult. The flotation of mica and quartz by anionic collector under acidic condition or negative cationic collector under alkaline condition can obtain good results. Generally, after scrubbing, desliming, PTMS magnetic separator and flotation, the purity of quartz sand can reach more than 99%, basically meet the needs of industrial sand.

what is magnetic separation in science？

 
Dilute acids have significant effects on the removal of iron and aluminum, while for the removal of titanium and chromium, stronger sulfuric acid and aqua regia are used for acid leaching. Usually, mixed acids composed of the above acids are used for acid leaching removal of impurity minerals. The control of various factors of acid leaching should be based on the requirements of the final grade of quartz, and the concentration, temperature and amount of acid should be reduced as far as possible to achieve the quartz purification at a lower cost of PTMS magnetic separator separation.
