There is a perception that mining low grade ore is an unavoidable consequence of ore deposit geology and mass mining. The energy cost and capital of used in the typically ‘Crush-Grind-Float’ method for low-grade deposits versus the output of minerals can drive poor productivity in a company.

CRC ORE’s technology ‘Grade Engineering®’ seeks to address this issue by focusing on extracting the metal more efficiently by separating the ore from the waste as early as possible.
