Such a circuit can counteract the effects of harder ore. coarser ore. decrease the size of SAG mill required, or rectify poor throughput due to an undersized SAG circuit. Notably, harder ore often presents itself to the SAG circuit as coarser than softer ore—less comminution is produced in blasting and primary crushing, and therefore the ...

Copper is used for electronics, construction, and metal alloys. Moly is mostly used to make metal alloys, and as a catalyst. As markets need copper and moly, their ores are separated, concentrated, and sold separately. This separation and concentration of copper and moly is called the "copper-moly flotation circuit."
