Activated Carbon in Gold CyanidationFEECO
Activated carbon is a critical component in the beneficiation of gold ore allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the deposit some silver ores may also be processed via cyanidation. Here too activated carbon is the catalyst for recovery of this precious metal.

Inquartation and Parting Refining ProcessGanoksin
Inquartation and Parting. The technique mirrors part of the Fire Assay process used in the analysis (assay) of gold. Inquartation involves initially diluting the gold in the refinable material to about 25 (literally quartering the gold) by melting with the appropriate addition of copper or silver granulating the melt so as to generate a high surface area and then treating with nitric acid.
