Australia

• Market focus: CIP, CIL and CIC gold recovery operations

• Common review areas: particle-size control, attrition, loading consistency and regeneration stability

• Supply considerations: batch consistency, documentation and long-distance logistics

• Content rule: use market-specific process context without implying a named customer

 

 

Technical Scenario 1: Diagnosing Screen Blinding, Carbon PSD and Attrition in a Western Australian CIP Circuit

 

Illustrative circuit image; no specific customer or site test data referenced.

 

Typical Operating Challenge: Carbon reaching elution below the expected loading target is not, by itself, proof of inadequate activated carbon. Loading is influenced by the solution gold profile, carbon concentration and advance rate, contact time, adsorption kinetics, equilibrium capacity, fouling, elution efficiency, and changes in ore or solution chemistry.

Technical Assessment: Build a stage-by-stage profile of dissolved gold and gold on carbon, then compare fresh and regenerated carbon using the same laboratory method and site solution where possible. Review recent changes in feed, carbon inventory, elution, regeneration, and carbon movement. Iodine number alone should not be used to explain a plant loading problem.

YICARB® Technical Approach: YICARB® would screen the AU Series against the site's process objectives through laboratory comparison and a controlled plant trial. Grade selection should consider both adsorption rate and equilibrium loading together with hardness, particle-size distribution, ash, and regeneration stability. The trial protocol should define sampling locations, frequency, and decision criteria before the product is introduced.

Verification Before Any Performance Claim: Compare the complete solution and carbon profiles before and during the trial, while recording carbon advance rate, carbon inventory, elution efficiency, regenerated-carbon condition, and relevant ore changes. Any statement about higher loading, lower consumption, or financial value must be calculated from the mine's approved mass balance rather than inferred from a product specification.
