Depletion gilding is most often used to treat alloys of gold with copper or silver ...
These templates use 01, 02 and 03 as the gold, silver, and bronze sort value, respectively. Sorting will operate numerically unless the column also contains any non-numeric text, in which case a text sort may sometimes occur (e.g. "10" is before "3").

In the US, for example, for the year 2011, secondary sources (new and old scrap) exceeded primary production. [3]
