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
Operation
Ferric chloride process includes the following process steps:
