From Leaching Through to Final Product Recovery

Hydrometallurgical circuits involve a chain of connected process steps. Each stage affects the next, from how material is leached, to how solutions are purified, to how the final product is recovered.

EMtek supports the full process pathway, helping clients define, optimise and integrate the systems required for safe, efficient and maintainable operation.

Process Capability

Leaching

Process development and engineering for heap, atmospheric and pressure leaching applications, including reagent consumption, residence time, materials selection, slurry handling and recovery optimisation.

Flowsheet development and plant design for solvent extraction and ion exchange systems, including stage configuration, phase separation, resin selection, organic handling, elution strategy and impurity management.

Engineering support for precipitation, crystallisation, evaporation, electrowinning and electrorefining circuits, with a focus on product quality, electrolyte management, solution handling and downstream separation.

What We Deliver

  • Heap, atmospheric and pressure leach circuit development
  • Solvent extraction flowsheet and plant design
  • Ion exchange system design and optimisation
  • Precipitation and crystallisation circuit support
  • Evaporation system design and assessment
  • Electrowinning and electrorefining engineering

Why EMtek

Hydrometallurgical systems require more than process theory. They need strong interface control across process, mechanical, piping, electrical, instrumentation, controls and layout design. EMtek brings these disciplines together to support recovery, product quality, safety and long-term operability.
