There are some deficiencies in the iron removal process of kaolin, such as high production cost, complex operation, low iron removal efficiency, and serious pollution to the environment and equipment corrosion in the chemical engineering. Kaolin has the characteristics of good crystal shape and fine grain size, and has great application potential in paper making and ceramic industry. PTMS magnetic separation can remove the iron (FE2O3) inside.
However, under the influence of dyeing elements such as Fe and Ti, its whiteness is low, and its application in paper making, coating and ceramics is limited. Among them, the resource reserves of high-speed rail kaolin (Fe2O3 content> 1.10%) reach 10 million tons. High efficiency PTMS magnetic separation iron removal process of kaolin, which has high iron removal efficiency and obvious whitening effect.
Due to the influence of geological causes, iron in kaolin mainly exists in the form of heavy minerals, and its magnetism is weak, mainly adsorbed on the surface of kaolin sheet in the form of thin particles, which cannot be removed by conventional chemical method and a physical method. Only by using PTMS magnetic separation combined physical method can it effectively achieve the predetermined goal of iron whitening.
