The impact of milling costs on total mine operating costs

The significant impact of comminution cost on total operating costs is indeed a proven fact;I believe that improved comminution economics will result from hybrid systems i.e. SAG Mill- HPRG systems; as the HPRG throughput is volume limited the easy work therefore should be done in a SAG mill and the hard work i.e.pebble crushing by HPRG.
