Measurement Instrumentation of continuous elution in gold extraction from carbon
Measurement of flow rates, temperatures, and pH to ensure optimal performance of gold elution process
Effectively remove adsorbed precious metals from activated carbon
Elution tanks are a vital component in the mining industry for the continuous recovery of precious metals, such as gold. These tanks play a crucial role in facilitating the separation of precious metals from loaded carbon or resin. Elution tanks typically consist of cylindrical vessels equipped with heating elements and agitators to facilitate the desorption of precious metals from carbon or resin particles. Operators at mining sites often encounter various pain points during the operation of elution tanks. Some of these challenges include inefficient temperature control, inadequate agitation, uneven flow distribution, and difficulties in monitoring critical parameters such as pH, to maintain optimal performance. By leveraging Emerson's measurement instrumentation, mining operators can enhance efficiency, overcome operational challenges, and ensure optimal recovery of precious metals.

Product Solutions
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
