This article maps the main carbon-loss pathways in CIP/CIL/CIC circuits — attrition and fines, screen escape, and handling or regeneration damage — and gives practical controls (durable carbon, PSD matched to screens, gentler transfer, controlled regeneration, carbon-balance monitoring) to stabilize inventory and cut avoidable make-up, since lost fines can carry adsorbed gold out of the circuit.

This article explains the regeneration sequence for gold-recovery carbon — elution and cleaning, controlled thermal regeneration, then cooling, screening, and return — and its benefits (restored adsorption activity, less fresh-carbon demand, stable inventory, better lifecycle economics), while stressing that regeneration is not the same as elution and must be monitored to avoid burn-off, fines, and physical damage.

A framework for comparing gold-recovery carbons on like-for-like test data across five dimensions — gold loading, kinetics, durability, PSD, and regeneration stability — using trial evidence to pick the best total operating value, not the highest single number.

A supplier-qualification framework covering six areas — gold-specific performance, manufacturing consistency, batch QC, documentation, technical support, and supply stability — plus warning signs to catch qualification risk before it becomes a plant problem

Mechanical durability is part of gold recovery: hardness resists fracture, abrasion resistance resists wear, and fines can carry adsorbed gold out of the circuit — so evaluate strength, PSD, weak particles, and handling together, not one COA number.

In the CIL (carbon-in-leach) gold recovery process, activated carbon enhances gold recovery efficiency through four key performance characteristics: rapid gold capture, effective gold loading, low wear and minimal loss, and stable regeneration. — When selecting activated carbon, one should not focus on a single indicator; instead, it must be managed within the context of the entire process loop.

This article explains how activated carbon in a Carbon-in-Pulp (CIP) gold recovery circuit works as a moving gold-collection phase — adsorbing gold-cyanide complexes, traveling counter-current to the slurry, being retained by interstage screens, and cycling through elution and regeneration — so that the carbon must be managed as part of the whole process, not judged by a single test value.
