Chinese maifan-stone (CMS) is Chinese traditional mineral medicine, in which there are lots of soluble mineral elements. In this paper static soaping to leach mineral elements and dry or we~ gringding maifan-stone simultaneously leaching mineral elements was studied. The result shows that: much more mineral elements were leached from Maifan-stone by the method that wet vibrating mill than by the method that soaking fine Maifan-stone after dry-milling. And the factors influencing on the mineral concentration such as milling time and solid/liquid mass ratio were investigated. Furthermore, the possibility of wet-milling simultaneously to leaching mineral elements from Maifan-stone to industrialization was analyzed, and pointed out that it has good industrialization foreground.
