Hydrometallurgy

Extraction in solution — leaching, purification and precipitation, where reagent balance and impurity control decide the economics.

Scope

  • Atmospheric, pressure and bio-leaching
  • Solvent extraction (SX) and ion exchange (IX)
  • Precipitation, cementation and neutralisation
  • Autoclave and pressure oxidation circuits
  • Solid–liquid separation and counter-current decantation
  • Water and reagent balance across the circuit
