Free, total & WAD cyanide in gold leach slurry & wastewater

Free cyanide is analyzed by direct titration or photometric detection depending on concentrations. For determining the more difficult and weak acid dissociable (WAD) metal-cyanide complexes, the online process analyzer is equipped with a digester, condenser, caustic absorber, and photometer modules to guarantee full recoveries of cyanide from complex metal cyanide solutions. The time-consuming analysis is completely automated. The benefits are time saving and consistency with no exposure to cyanide offering safe and trusted measurements throughout the plant.
