What was developed or tested
Hydraulic reclamation, slurry transport and conventional flotation use substantial existing mine and port infrastructure; operations began on tailings in 2018.
What the evidence supports
Australia’s most prominent commercial tailings-recovery example. It demonstrates that grade, scale and inherited infrastructure can make secondary mining competitive.
Environmental and technical uncertainty
Retreatment can support progressive rehabilitation, but water balance, geotechnical change and residual-tailings closure remain core controls.
Benefit-case screening lens
Potential value: Recovered metal revenue, critical-mineral supply, improved resource efficiency and possible reduction of a legacy or active tailings inventory.
Deployment constraints: Representative grade, mineral deportment, recovery, throughput, reagents, energy, CAPEX, commodity price and management of the reprocessed residue.
Question before applying elsewhere
Do grade variability, mineral deportment, recovery, reagent demand and residual-waste management support a viable site-specific flowsheet?
