Dry method
Processing principle: Under the effect of the mechanical power and wind power, the raw ore causes hit, cut and friction each other between the material and the medium, thus causes the material particle to become fine.

Wet method
Processing principle: Under the aqueous medium condition, the sericite mica and the quartz are stripped by roller grinding and stripping. Next, through hiting mutually and cutting, causes the material granular to become small. Last, remove the sand through the water power eddy to make the sericite mica granular to be concentrated.
