Carbon In Leach Plant Monitoring
The “Carbon In Leach” (CIL) is a production process used in gold recovery where the ore slurry is treated to recover the gold and other metals.The CIL process is therefore the heart of the gold mining operation and needs to be closely monitored in order to maintain precise control of the pH, DO, Redox, density, cyanide concentration and temperature in order to recover the maximum residual gold within the slurry.
Opto Controls (Pty) Ltd has developed a web based remote monitoring solution with Mobie HMI and real-time graphical interface to the CIL production process with real-time and historical super-trends of the process, configurable SMS and e-mail alarms and a production reporting database. This allows metallurgists the ability to view the CIL production process at any location in real-time, and immediately respond to any imbalance in the process. Maintenance crew can respond to configured alarms such as blockages, low or high pressures, power trip conditions etc. while management will have the ability to query a lack of a timely response to any configured alarm condition. Operators can identify problematic areas and view any fault at its actual location within the plant, while being able to witness and verify the repair and clearance of the fault at its source with their mobile device.
