AI Technical Summary
Existing methods for detecting cyanide concentration rely on manual titration, which is susceptible to subjective influence and has low accuracy. These methods are difficult to adapt to the real-time requirements of whole-mud cyanidation carbon slurry gold extraction processes. Furthermore, online detection equipment is severely affected by solid particle crystallization, calcium salt deposition, and impurity ions.
A cyanide concentration detection device is used, and a color sensor detects the rate of color change in the titration chamber. The controller automatically determines the titration endpoint. By combining the order of adding the colorimetric reagent and the titration reagent, the titration endpoint determination is automated, eliminating interference from sample color changes.
It improves the accuracy and efficiency of cyanide concentration detection, reduces measurement errors, and achieves effective closed-loop control of the automated sodium cyanide dosing system, making it suitable for a wide range of concentration detection.
