Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface The grinding wheel or plate typically rotates at a high speed around 2001000rpm and a coarse bonded abrasive 40 m is used Grinding is quick and relatively easy process but can grind size of the ore can have on copper concentrate production during flotation process Therefore this research was more focused on determining whether the size distribution of the ore after comminution would cause significant impact on copper ore response in the floatation process Comminution
