Recovery of Free Metallic Copper From the Grinding Circuit ...

In particular ore types, the copper recovery by flotation is poor. This was believed to be due to the native copper loadings in the float feed. Native copper is visible in the float tail in relatively large quantities. The recovery of native (metallic) copper from the grinding circuit was believed to be the best way to reduce this tail grade.
