Optimizing Carbon-in-Leach process for Gold Extraction in Mining
Maximize the recovery of precious metals in a sustainable and cost-effective manner
Optimizing Precious Metal Recovery in Mining during Carbon-in-Leach
Carbon-in-Leach (CIL) is a widely adopted process in the mining industry for extracting precious metals, particularly gold, from ore. This technique involves the use of a carbonaceous material to adsorb the gold, followed by its extraction through chemical means. The efficiency and success of CIL greatly depends on various factors, such as the ore composition, carbon quality, contact time, pH, temperature and dissolved oxygen. One common challenge of this process is the variability in ore grade and composition. Another significant challenge lies in accurately monitoring and controlling pH, temperature, and oxygen levels throughout the process, as combined deviations can have detrimental effects on process stability. With a range of advanced measurement instrumentation technologies, Emerson enables mining operations to maintain optimal conditions for efficient carbon-in-leach processes.

The Rosemount 396P pH Sensor/ORP Sensor, with integral cable, is specifically designed for improved life in harsh, dirty, and abrasive applications such as lime slurry waste treatment, paper machine headbox and pigment/dye applications, where large quantities of suspended solids are present. The pH/ORP sensor features a coating resistant TUpH large area reference junction and a rugged polypropylene body construction for maximum chemical resistance.
- Minimum pH/ORP sensor maintenance due to TUpH reference technology which ensures steady pH signal when sensor is coated
- Maximum pH/ORP sensor life due to helical reference pathway which hinders reference poisoning and cracking resistant glass
- SMART enabled for pH measurements
