Metal Recovery

Unlocking residual value from mine tailings and process residues — improving project economics while reducing environmental liability.

Capabilities

What we deliver

Tailings characterisation, metallurgical testing, and recovery modelling
Hydrometallurgical and pyrometallurgical process selection
Electrocoagulation-assisted metal precipitation from leachate
Critical minerals focus: lithium, cobalt, nickel, copper, rare earths
Tailings reprocessing facility engineering and EPC delivery
Environmental closure integration — reducing acid mine drainage (AMD) risk
Collaboration with national laboratories and research institutions

As global demand for critical minerals intensifies, historically uneconomic tailings deposits are becoming viable resources. OPTI Industries applies a multi-disciplinary approach — combining process chemistry, automation, and water treatment — to design recovery systems that extract value from low-grade and legacy tailings while satisfying environmental obligations. Our current R&D activities with Oak Ridge National Laboratory (ORNL) position OPTI Industries at the forefront of next-generation mineral recovery technologies.
