Moebius process
/ˈməːbɪəs ˌprəʊsɛs/ /ˈməʊbɪəs ˌprəʊsɛs/noun
An electrolytic process for refining silver and separating any gold that may be in it, in which anodes are made of the silver to be refined and placed in a solution of silver nitrate together with cathodes of pure silver or stainless steel.
- When a current is passed base metals go into solution, pure silver is deposited on the cathode, and any gold accumulates in bags placed around the anodes..
Origin
Early 20th century; earliest use found in Encyclopaedia Britannica. From the name of Bernhard Moebius (fl. 1884 in Mexico as a German subject), who devised the process + process.
