Maximize the Yield and Quality of Final Product in Solvent Extraction for Mining
Efficiently monitor ore grades, recovery rates, and energy consumption with Measurement Instrumentation
Precisely measure and assess the aqueous phase for solvent extraction
Solvent extraction involves the use of chemical solvents and specialized equipment to separate valuable metals or minerals from their ores. To ensure optimal performance in mining operations, operators rely on various key performance indicators (KPIs) to monitor and assess the efficiency of the process. These KPIs include factors such as extraction yield, organic-to-aqueous ratio, organic phase impurities, and solvent losses. By attentively analyzing and optimizing these metrics, operators can significantly improve resource recovery, increase operational efficiency, and reduce costs. For comprehensive monitoring and control of these KPIs, operators can turn to Emerson's Measurement Instrumentation solutions. Emerson's cutting-edge technology empowers mining companies to achieve greater accuracy, reliability, and profitability in their solvent extraction processes.

Product Solutions
The Rosemount 228 Toroidal Conductivity Sensor reliably measures conductivity in highly conductive electrolyte solutions up to 2 S/cm (2,000,000 µS/cm). These conductivity sensors work in dirty and corrosive applications where metal electrode sensors would otherwise fail. A robust sensor design makes the Rosemount 228 conductivity sensor ideal for measuring concentrations of acid, base and salt solutions.
