METHOD FOR RECOVERING GOLD FROM ACTIVATED CARBON

摘要

The purpose of the present invention is to make it possible: to, before gold is eluted, effectively remove copper, iron, and sulfur, which are impurities from the standpoint of gold recovery, from activated carbon on which gold has been adsorbed; and to efficiently elute the gold. Provided is a method for eluting gold (Au) from activated carbon on which at least sulfur (S) and Au have been adsorbed, the method comprising cleaning the activated carbon with an alkali before gold is eluted and thereafter eluting the Au.
