Outotec® Copper Pressure Leaching Process

Get sustainable and economical copper recovery from copper sulfides with very high copper leach extractions. The Outotec 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
