Enhancing Efficiency with Measurement Instrumentation in Mining Neutralization Processes
Maintaining accurate pH control, precise chemical dosing, and thorough reagent mixing
Navigating Challenges in Chemical Neutralization in Mining operations
Neutralization is a chemical process which mining operations use to control the pH of critical slurries and solutions. These mining facilities often face challenges controlling pH. Maintaining accurate pH control, precise chemical dosing, and thorough reagent mixing are crucial aspects that can significantly impact operational efficiency and regulatory compliance. Additionally, fluctuating feed composition, equipment corrosion, and limited real-time monitoring capabilities further complicate matters for mining operators. By leveraging Emerson's cutting-edge sensors, precise measurement tools, and reliable control systems, mining facilities can streamline neutralization processes, optimize pH control, and drive overall operational performance to new heights. Emerson's Measurement Instrumentation paves the way for enhanced efficiency and effectiveness, revolutionizing the approach to neutralization.

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
