copper The World's Healthiest Foods

Storage of foods does not significantly affect their copper content. Like other minerals, copper will stay available in your foods as long as they are properly stored for recommended periods of time. Processing whole grains into refined ones by removing the outer layers will significantly reduce copper content.

Oxygenfree copper Wikipedia

During the copper smelting process, oxygen is deliberately injected into the melt to scavenge impurities that would otherwise degrade conductivity. There are advanced refining processes such as the Czochralski process than can be used to reduce impurity levels to below the C10100 specification by reducing copper grain density.

DuraChrome Hard Chromium Plating

The commercial process of chromium plating resulted principally from the work of C. G. Fink and C. H. Eldridge, in 1923 and 1924. Lieblich also made similar discoveries more or less simultaneously in Germany, but confused them by overemphasis on the supposed importance of the trivalent chromium also present in the chromic acidsulfate bath.
