  • Gold

    When a highly-selective resin is not required, AmberSep™ 21K XLT Strong Base Anion Resin can be used to capture the gold since gold extracted by cyanidation is in the form of anionic aurocyanide complex (Au(CN) 2-). Elution from the resin can be achieved with a more strongly adsorbed anion; zinc cyanide or thiocyanate are commonly employed.
