pH/ORP Sensors in Metallurgical Applications

2017-05-12T19:10:18+00:00February 24th, 2017|

Importance of pH Measurement: Hydrometallurgical concentrating and refining applications require pH/ORP sensors to withstand aggressive environments while maintaining accurate measurement. Processes such as cyanide leaching (e.g gold) and solvent extraction (e.g. copper, nickel, zinc) require pH and ORP to be at very specific values to yield the desired chemical species. pH may need to be [...]

High Purity pH Measurement

2017-05-12T19:25:18+00:00November 1st, 2016|

Instrumentation and Operational Considerations for On-Line pH Measurement in Samples Below 10 μS/cm Conductivity Ordinarily pH measurements are made in water with 1,000 to 10,000 μS/cm conductivity. The conductivity comes from dissolved solids which are typically salts but also acid or base. These dissolved substances are in the solution in ion form which makes such [...]
