pH/ORP Sensors in Metallurgical Applications

  • Importance of pH Measurement:
    Hydrometallurgical concentrating and refining applications require pH/ORP sensors to withstand aggressive environments while maintaining accurate measurement. Processes such as cyanide leaching (e.g gold) and solvent extraction (e.g. copper, nickel, zinc) require pH and ORP to be at very specific values to yield the desired chemical species. pH may need to be controlled as precisely as ± 0.05 for some processes. Even where this level of precision is needed, process environments are typically extremely aggressive to the sensor.
