Floatation services by Arnofio

Bench Scale Specialists

Flotation is a method of mineral concentration and is used for the recovery of sulphides, oxides, industrial minerals and coal. Laboratory testing is a costly and time consuming process, thus quality results and accurate conclusions are essential.

Flotation test work conducted by Arnofio includes:

  • Rougher and cleaner batch testing for investigation into flotation conditions such as grind size, pulp density, pH, reagents and controlled potential sulphidisation.
  • Kinetic testing to provide timed concentrates for grade-recovery information and mineral flotation rate data.
  • Locked-cycle testing to investigate the effect of recycled tailing products and water on flotation in a continuous plant situation.
  • Laboratory flotation services are offered in gold, silver, base metals and industrial minerals.

Other laboratory services include:

  • Comminution for preparation of flotation charges or sizing data for liberation studies.
  • Particle size distribution for liberation studies and grind establishments.
  • Sample preparation including freezing sulphide flotation charges to prevent oxidation and preparation of representative samples for gold assay.
  • Settling and filtration testing.
  • Report writing for work conducted either in-house or externally.

We offer tailored test work programs to suit your budget and needs with an emphasis on quality and turnaround time.
