mining difference between milling and grinding

Mining and milling

During milling the uranium bearing ore is initially crushed (if preceded by conventional mining), which is typically a dry process, and then ground into a slurry, which is a wet process. The intent of crushing and grinding is to effectively increase the surface area to volume ratio of the material, which facilitates chemical leaching.

Comminution and classification technologies of iron ore

The mill is filled with suitable grinding media, and the space between each of the disks is essentially an individual grinding chamber. As a result, the mill effectively comprises eight grinding chambers in series. The media is set in motion by the action of the grinding disks, which accelerate the media nearby radially toward the shell.
