Moebius processn.

Brit.

/ˈməːbɪəs ˌprəʊsɛs/,

/ˈməʊbɪəs ˌprəʊsɛs/, U.S.

/ˈmoʊbiəs ˌprɑˌsɛs/

Origin: From a proper name, combined with an English element. Etymons: proper name Mœbius , process n.

Etymology: < the name of Bernhard Mœbius (fl. 1884 in Mexico as a German subject), who devised the process ( Brit. Patent 16,554 (1884)) + process n. O.E.D. Suppl. (1976) gives the less naturalized pronunciation (mö·biɒs) /ˈmæːbɪəs/.

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.
