What equipment is efficient for removing iron from kaolin?
September.24,2024
Magnetic separation is used to remove weak magnetic staining impurities such as hematite, siderite, pyrite and rutile from kaolin. Magnetic separation does not require the use of chemical agents and is environmentally friendly, so it is widely used in the purification process of non-metallic minerals. Removing weak magnetic impurity particles from kaolin requires a higher magnetic field magnetic induction intensity and magnetic field gradient. The development of magnetic separation technology and the upgrading of equipment have enabled the magnetic separation and purification of non-metallic minerals such as kaolin to be effectively realized.
High-performance strong magnetic separation equipment vertical ring high gradient magnetic separator, magnetic separation and purification process solves the problem of development and utilization of low-quality kaolin resources that have high iron content and are not commercially valuable, but a single magnetic separation operation is also difficult to obtain high-quality kaolin products. At present, it is also necessary to cooperate with other processes such as chemical bleaching to further reduce the iron content of kaolin products.
