    In an electrolytic silver refining process, crude silver is anodically dissolved while refined silver is cathodically deposited and at the accompanying (impurity) metals are selectively extracted from the used (spent) electrolyte and transferred to an aqueous phase. The used electrolyte is enriched in silver and accompanying metals are cathodically deposited and thus removed from the electrolyte.

    In electrolysis, an external power source supplies the free energy required to drive a cell reaction in its non-spontaneous direction. An electrolytic cell is in this sense the opposite of a galvanic cell. In practice, the products of electrolysis are usually simpler than the reactants, hence the term electro-lysis.
