Regeneration Stability

Maintain Performance Through Repeated Carbon Cycles

Gold recovery carbon is repeatedly loaded, eluted, and thermally regenerated. Effective lifecycle performance depends on the carbon retaining both adsorption activity and mechanical integrity through these operating cycles.

Regeneration performance is influenced by the condition of the incoming carbon, fouling, acid washing, kiln temperature, residence time, atmosphere, and carbon handling. Excessive thermal exposure can weaken carbon, while incomplete regeneration can leave contaminants that restrict adsorption sites.

YICARB Approach: Dense coconut shell structure, controlled activation, and high hardness provide a strong foundation for repeated use. Mines should monitor activity, hardness, attrition, and particle size distribution after regeneration to determine the appropriate operating window for their circuit.
