Hardness & Attrition Resistance

Protect Carbon Integrity and Reduce Fines

Activated carbon is exposed to repeated handling, pumping, agitation, elution, and regeneration. Weak particles can crack or abrade into fines, and fine carbon may carry adsorbed gold beyond the recovery screens.

Ball-pan hardness provides a standardized basis for comparing the mechanical strength of granular activated carbon. It should be considered together with attrition testing, particle size analysis, and qualification under actual operating conditions, because circuit design and carbon handling practices also influence carbon loss.

YICARB Approach: Every AU grade is specified at hardness of ≥98% and is designed to maintain particle integrity during circulation and handling, helping reduce carbon breakage and potential gold-bearing fines.
