The Challenge

To investigate the effects of using impure water on the flotation of rare earth bearing minerals as an alternative to using high-cost reverse osmosis water for processing.

The Solution

  • Understand the effect of water quality variation on flotation recovery and grade of rare earth minerals.
  • Understand the interactions and efficiency of flotation reagents in impure water.
  • Understand how impure water affects the flotation behaviour of target and gangue minerals.
  • Understand the tolerance for impurities while achieving the desired flotation efficiency.
  • Identify less expensive water treatment options to produce suitable water for REO flotation.

Proposed Benefit to WA

Reduction in the requirement for, and consumption of, high-quality water, particularly in locations where water is scarce, potentially decreasing operating costs for companies.
