The gold is oxidized and dissolved as a salt. In this second, dissolution step, water, oxygen, and cyanide are added to the ore to transfer the gold from the solid phase to a water-based gold-cyanide complex. It's at this stage that Linde's dissolved gas management solution for gold extraction can really add value.
