Development status of joint process of rare earth mineral processing in China

The development status of dressing technology for rare earth is introduced by elaborating on its mineral processing flowsheet.In this paper, it summaries a variety of joint processes such as magnetic separation-flotation, magnetic separation-gravity separation, gravity separation-flotation, magnetic separation-gravity separation-flotation processes and some chemical leaching processes.Different types and structural properties of ores result in different choice of technology and reagent regime.It is of important significance to analyze the separation methods for the development of rare earth mineral processing.
