Hydrometallurgical Process - an overview

The process uses fine milling for reducing the grain size of the charge to approximately 16–18 μm, followed by a leaching in ferric sulphate at approximately 80 °C and atmospheric pressure using oxygen or blown air. Copper is produced by conventional SX/EW technology. The process has been applied efficiently on the pilot plant scale.
