Electrolytic processes for gold and other precious metals

The electrolytic refining process for gold uses hydrochloric acid as the electrolyte. The anode is made of gold alloy and the cathode is usually a thin sheet of high purity gold. The electric current ionises the electrolyte and transfers dissolved gold from the anode to the cathode, thereby increasing the purity of the gold at the cathode. ...

Challenges in the Electrolytic Refining of Silver—Influencing the …

Copper Co-deposition. Looking at the standard potential of Cu (Cu/Cu 2+ = 0.345 V and Cu/Cu + = 0.522 V), it is apparent that during electrorefining of Ag, Cu will mostly dissolve into and enrich in the electrolyte. Partial occurrence of Cu in the anode slime can be detected. This is more or less due to oxidic Cu present in the crude silver …

Copper Electrolytic Refining Process Explained

The ideal of the copper hydrometallurgist is to secure, in the hydro-electrolytic extraction of copper from its ores with insoluble anodes, conditions comparable with those which obtain in the electrolytic refining of copper with soluble anode. By means of the step system it is believed that these conditions are more nearly approached than …
