Copper Ferric Leaching Process

Achieve effective copper recovery from secondary copper sulfides

Metso Outotec's ferric leaching process is a sustainable and economical solution that it is especially effective on low-grade and impure copper feed materials. The process uses highly effective atmospheric leaching technology combined with world-renowned VSF solvent extraction and electrowinning technology.

  • Provides highly effective copper recovery from secondary copper sulfides    
  • Produces copper as standard LME-A grade cathodes    
  • Uses atmospheric leaching technology without fine-grinding    
  • Lowers oxygen and lime(stone) consumption due to sulfide oxidation to elemental sulfur    
  • Runs more economically at lower capacities than traditional processes
