Abstract: The recent development of rare-earth permanent magnets has impacted the field of magnetic separation. The permanent magnets technology led to the advent of various magnetic separators particularly designed for application in mineral processing. In this paper, a new type of rare-earth PHGMS was developed possessing a higher magnetic field strength in the working zone by means of finite element analysis technique and its operation mechanism was analyzed. The NdFeB permanent magnets used possess properties of 304 kJ. m(-3) stored energy, and their flux levels exceed 1. 2 T. The combination of rational structure and suitable matrices can offer an effective separation of industrial minerals such as kaolin feldspar, etc. Compared with conventional high intensity electromagnetic separators, the equipment can reduce electrical energy by over 80%, with lower operation and maintenance costs, and less installation space.
