electromagnetic separation

During high temperature roasting, iron-containing impurities become oxidized to remove easier substances; carbon impurities are burned, and sulfide breaks down into gas to escape. At the same time, the high-temperature roasting can also improve the chemical reactivity of the roasting products, so that they can show better performance in the subsequent applications. However, the iron removal method of high-temperature roasting PTMS magnetic separation also has some disadvantages.

PTMS magnetic separation

First, the energy consumption is high because the kaolin needs to be heated to a higher temperature; Second, some harmful gases, such as sulfur dioxide, which are easy to cause environmental pollution. Therefore, when using the roasting PTMS magnetic separation purification method, the corresponding environmental protection measures need to be taken to reduce the impact on the environment.

what is magnetic separation in Kaolin？

Codens/ flocculation is a method to remove titanium impurities in kaolin using physiochemical principles. In kaolin slurry, iron-titanium impurities usually exist in the form of fine particles, which are difficult to remove directly by conventional methods. The condensation / flocculation method is to condense and flocculation the iron and titanium impurities by adding specific agents to the pulp, so as to realize the separation of kaolin and iron by PTMS magnetic separation.
