Magnetite separation method
According to the different types of iron-bearing minerals, magnetite ore can be divided into single magnetite and mixed ore. Generally, single magnetite ore is often separated by weak magnetic separation method, while polymetallic magnetite ore and mixed ore are mostly separated by a combined process composed of a variety of beneficiation methods, including magnetic separation method, flotation method , gravity separation method, and magnetization roasting. Magnetic separation method, reduction roasting magnetic separation method, etc. 1. Single magnetite beneficiation method Most of the iron minerals in single magnetite are magnetite. Because single magnetite has simple composition, strong magnetism, easy grinding and easy selection, weak magnetic separation method is often used for separation. ◆ When the grinding particle size is greater than 0.2mm, most iron ore magnetic separation plants often use a one-stage grinding-magnetic separation process; ◆ When the grinding particle size
