RECYN PROCESS

THE RECYN™PROCESS TECHNICAL AND ECONOMIC SUPERIORITY:

HIGH EFFICIENCY High recovery efficiencies of free and metal complexed cyanides, toxic metals, and precious metals. RESISTANCE TO POISONING Investigations have shown the resin to be barely affected by organic foulants or inorganic poisons, even after long term usage. LOW ABRASION LOSSES Operations have shown that the mechanical strength of the resin results in low abrasion losses; an order of magnitude lower than carbon. STABLE OPERATION Temperature variations and the presence of slurry solids have negligible effect on performance. SIMPLE ELUTION The resin can be effectively eluted at ambient temperatures and at atmospheric pressure. Elevated temperature and pressure vessels are not required. EASE OF HANDLING The close sizing and regular shape of the resin beads assist selection of screens and reproducible screening performance. ECONOMIC CYANIDE RECOVERY Recovered cyanide costs 50% less than new cyanide; and the process eliminates detox requirement. IMPROVED METAL RECOVERY The lower cost of cyanide recycle allows higher cyanide levels to be kept in the leach circuit thereby potentially increasing silver recovery.
