Performance Metrics — what these mean for your plant
Higher K and R values = more gold adsorbed per unit of carbon and faster kinetics — directly increases gold recovery and throughput.
Low attrition & high hardness = fewer fines, less screening and electrowinning contamination, reduced makeup carbon and lower OPEX.
Optimized particle distribution (6×12) = stable bed porosity, less screen plugging and predictable hydraulic behavior.
Excellent elution response = efficient gold strip and reliable regeneration cycles, improving carbon life and cash flow.
