Copper Pressure Leaching Process

Get sustainable copper recovery from copper sulfides with very high copper leach extractions

The Metso copper pressure leaching process combines our highly effective pressure oxidation and leaching technology with world-renowned VSF solvent extraction and electrowinning technology. The process also enables precious metals recovery from leaching residue with cyanide leaching technology.

  • Recovers copper effectively from copper sulfides    
  • Produces copper as standard LME-A grade cathodes    
  • Offers pressure leaching technology without fine-grinding
  • Recovers precious metals with highly effective conventional cyanide leaching
  • Runs more economically at lower capacities than traditional processes    
  • Results in environmentally stable leaching residue

Copper pressure leaching process consists of the following main steps:


  • Concentrate repulping    
  • Pressure oxidation of sulfides    
  • Hot curing    
  • Solid-liquid separation    
  • Neutralization    
  • Copper solvent extraction    
  • Copper electrowinning    
  • Water balance management and bleed treatment
