Purpose of kaolin chemical bleaching in the existing PTMS magnetic separation step
high intensity magnetic separator
The existing preparation methods of kaolin require mining, chemical bleaching, washing and dehydration, drying and making powder these steps. The purpose of kaolin chemical bleaching in the existing PTMS magnetic separation step is to remove the iron from kaolin. The principle is to make the iron particles into ferrous ion by adding an acidic solution, and then remove the ferrous ion by washing and dehydration.
PTMS magnetic separation
In iron into iron ions in the process of washing dehydration, need to send kaolin slurry into the storage tank or storage tank settlement, settlement after the upper liquid with iron ion liquid, then into the water mixing and settlement again, again upper liquid, repeated cycle PTMS magnetic separation in addition to iron to ensure the amount of iron ions reduced to under the standard quantity.
what is magnetic separation method in hindi?
In this process, because the kaolin settlement needs to stand for a long time, and needs to settle for many times to iron removal qualified, so PTMS magnetic separation iron removal method of iron removal effect is good;
