Case Study Savannah Mine: Nickel Flotation With Pyrrhotite Gangue

We tested a nickel sulfide ore from the Savannah mine with an on-site laboratory flotation cell. The standard flotation reagent suite was compared with the addition of 300 gpt of Pionera F-300 and an additional aeration step in a rougher flotation setting.


Key takeaways:

  • The kinetic test results indicate a significant improvement of nickel grade in the final concentrate is achievable.
  • Increased nickel grade yields financial benefits.
  • Further optimisation of application point and dosage are pending.
