dc.description.abstractIn 2004, Mintek recognised the gold mining industry‘s need for an online free and WAD cyanide measurement device and went about extending the existing free cyanide analyser,the Cynoprobe to include WAD cyanide measurement. The WAD cyanide analysis technique was to be based on ligand exchange, which required the selection of an appropriate reagent,with amperometric finish. Thereafter, the technique was validated in the laboratory to include the capabilities of the prototype instrument in terms of accuracy and precision (0.5-100 ppm WAD CN). Various local trials were conducted in order to validate the measurement and the robustness of the instrument in an industrial environment. Successful trials (<10% error with respect to laboratory analysis) led to international application and exposure to complex ore types and process solutions.en_ZA
