The OI Analytical CNSolution™ 9310 On-line Cyanide Analyzer is designed to measure available cyanide in precious metal leaching solutions by U.S. EPA Method OIA-1677 and ASTM D 6888-09. The gas-diffusion amperometry technique in these methods has been demonstrated to be free of interferences from copper and metallic sulfides that impair the accuracy of traditional techniques such as titration.

Deploying CNSolution 9310 On-line Cyanide Analyzers enables gold and silver mills to accurately measure and control cyanide levels at key points in the cyanidation process. Continuous on-line monitoring provides a dynamic view of the process rather than periodic snapshots obtained by grab sampling and laboratory analysis. Improved accuracy facilitates tighter control of cyanide usage and can significantly reduce a plant’s operating costs.
