Feb 24, 2015· In comparison, the Boddington copper gold project CAPEX (Seidel et al. 2006) for the HPGR circuit option was 7 percent higher than the SAG option. Therefore, it appears that there may not be any significant CAPEX "penalty" for the adoption of more energy-efficient grinding technologies when considering magnetite ore processing.
