A new technology to significantly improve the recovery of copper from solvent extraction organics.
Acid sulfate copper leach process liquors
Use a soluble pH modifier that produces no precipitate in mixers.
Indirectly uses the cheapest alkali – limestone.
- Neutralise acid generated in the extraction mixer-settlers to drive higher copper extraction.
- Higher reagent loading.
- No complex pH control necessary.
- Easily incorporated in a “standard” Cu-SX flowsheet.
- Simple retrofit to an existing plant.
