Electrolytic Refining Meaning, Electrorefining of Copper

Electrorefining also offers a very high metal purity. Using a molten salt or non-aqueous electrolyte, electrorefining methods are used and are indeed the focus of further research. This is due to the possibilities they offer to increase current densities and refining through lower oxidation states that are not stable in water (e.g. copper refining via Cu + would nearly halve the energy

PRESSURE LEACHING OF DECOPPERIZED COPPER ELECTROREFINING

The processing of copper anode slimes is an additional economic driver for copper electrorefineries, due to the fact that slimes contain precious metals such as silver, gold and platinum group metals (PGMs) (e.g. Pt and Pd) as well as base metals like copper, nickel, selenium, tellurium and impurity elements such as lead, antimony and bismuth.

DEVELOPMENT OF CHARACTERIZATION METHODS FOR

The impurity elements in electrorefining report to either slimes or electrolyte. The major elements reporting to electrolyte are nickel and arsenic, whereas silver, lead, selenium and tellurium report to slimes. The dominant phases in anode slimes are complex oxides, lead sulphate and Ag-Cu selenides (Chen and Dutrizac, 1990).
