Typically the size range of ore treated in heavy media separation ranges from 10 mesh to 8 inch, and sometimes down to 28 mesh in particle size. The particle size of the media is also important, since this affects the separation size. Generally a good grade of media of magnetite or ferrosilicon needs to be 90% to 325 mesh.
