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

Copper head grade averages about 2% and gold 3 to 5 grams/tonne. Native (metallic) copper averages 20% of total copper. 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 processing plant reflects a typical copper flotation plant. The rougher flotation produces a bulk concentrate and final tails, which is then reground and sent to cleaner flotation. The cleaner tails go to scavenger flotation, while the concentrate, with a grade of over 20% copper, goes to the next process.
