how to elute gold from carbons

May 27 2010 · If gold chloride was originally used the carbon reduces the gold chloride to gold metal The gold is often recovered by burning Other schemes involve first mechanically separating the gold metal from the carbon by abrasion or by such things as ultrasonics The gold is then recovered by gravity methods The following attachments give all of this in more detail
