Purification of Gold by Electrolysis

The Moebius Process of Purification of Gold by Electrolysis is now in successful operation and is said to be specially suitable for refining copper bullion containing large proportions of silver and gold with small quantities of lead, platinum, and other metals, but is chiefly used in parting dore silver containing not more than 20 per 1,000 of base metals.

Electrolytic Refining Mining Fundamentals

This process is known as the Wohlwill process. The Miller chlorination process is an economical refining process that separates gold of about 99.5% purity, which can then be electro-refined to improve purity to 99.999%. Silver The electrolytic silver refining process includes a crude silver anode and a refined silver cathode.
