The temperature at which activation is carried out is between 800 to 1000 °C. In this step the steam reacts with the carbon in the char to create the high internal surface area of ± 1000 m²/g. The activation step typically takes 24 hours and consumes 1 kg steam / kg carbon/ hour.

In the thiosulfate leach process, thiosulfate is used as an alternative to cyanide, to enable gold recovery from preg-robbing ores. The gold-thiosulfate complex does not adsorb onto carbon as does gold-cyanide, but is instead loaded onto resin, in a resin-in-leach process.

In the gold leaching process, barren (non-metal bearing) process solution is pumped to the active leach pads and applied at the rate of 0.004 gpm/sq ft. Barren solution sodium cyanide concentrations are maintained around 0.20 to 0.25 pound/ton of solution (maximum Weak Acid Dissociable (WAD) cyanide value of 50 ppm).
