Mœbius|ˈmøːbɪəs|
The name of Bernhard Mœbius (fl. 1884 in Mexico as a German subject), used attrib. to designate an electrolytic process that he devised for parting gold and silver (Brit. Pat. 16,554 (1884)), in which anodes of bullion and cathodes of silver or stainless steel are placed in a solution of silver nitrate, so that base metals go into solution and silver is deposited on the cathode, leaving behind the gold.
1902Encycl. Brit. XXVIII. 110/1 Alloy scrap containing chiefly copper with, say 5 or 6 per cent. of gold, and other metals, and up to 40 to 50 per cent. of silver, is often treated electrolytically. Obviously, with modifications, the Mœbius process could be applied. 1970Materials & Technol. III. iv. 295 Electrolytic refining [of doré metal] is now widely employed. In the Moebius process the impure silver is cast into anodes which are enclosed in cotton or linen bags and dissolved electrolytically in acid silver nitrate solution. |
