Gold Processing Steps 101: Essential Guide

Once the activated carbon is loaded with gold, it's removed from the adsorption columns and goes through a process called elution to strip off the gold. The loaded carbon is treated with a hot (90-120°C) caustic solution containing 1-2% sodium hydroxide (NaOH) and 0.1-0.2% cyanide (NaCN).

Atmospheric Elution Process

A total of 20 bed volumes (10 + 10) are required to eluate the gold down to 200-300 ppm, an elution efficiency of 82%. The results from the pilot run were not encouraging due to the extruded carbon use. The indication from the test runs, however, is that the elution efficiency is at least equivalent to the batch system.

ACTIVATED CARBON IN GOLD RECOVERY
