Electromagnetic Separation for Quartz Processing line

The roasting process is a complex thermochemical reaction that requires to be carried out in specific roasting furnaces. During the roasting process, controlling parameters such as temperature, time, and atmosphere is crucial. Generally, roasting temperatures range from several hundred to over a thousand degrees Celsius, with different minerals and PTMS Electromagnetic Separator process requirements varying accordingly.

PTMS magnetic separation

After roasting, mica and tourmaline minerals become strongly magnetic iron oxide, which can be effectively separated from kaolin by using PTMS Electromagnetic Separator. Flotation purification of kaolin is widely used in industry, and with the continuous progress of science and technology, its processes and equipment are also constantly improved and updated.

what is magnetic separation in Kaolin?

The basic principle of flotation is to utilize the differences in physical and chemical properties of mineral surfaces, especially their hydrophobicity, by adding appropriate flotation reagents. This allows the target minerals to adhere to bubbles, thus achieving separation from other minerals. In the purification process of kaolin, flotation equipment not only removes iron impurities but also other impurities such as quartz and feldspar.
