Carbon-In-Column

With carbon-in-column operation, the gold cyanide solution flows through a series of fluidised bed columns in an up-flow configuration. Fluidised bed carbon columns can process solutions that contain as much as 2 to 3 wt% solids, thus making them well suited for heap leach applications which are often high in solids content.

Oxygen-based solutions for gold extraction | Linde

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.

Efficient gold-cyanide recovery from activated carbon by

Activated carbon, with its extensive network of pores, acts as an adsorbent. In gold mining, it traps gold cyanide complexes (Au (C N) 2 −)formed by leaching gold ore with cyanide solution (NaCN) [29]. This adsorption process is primarily physical, involving weak attractive forces between the gold complex and the carbon surface [29]. 2.
