Introduction of the efficiency of copper ore comminution
  • Comminution Centre for Minerals Research
    Comminution Centre for Minerals Research

    Comminution Comminution utilises energy to reduce the size of ore particles in order to liberate embedded mineral grains so that they can be recovered in the subsequent process stages The research under this theme focusses on understanding how energy is used in devices that use different breakage mechanisms to achieve size reduction and how
