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 [...]
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 [...]
Case Study – High purity Thermo Scientific Orion ROSS pH electrode provides reliable measurements and cost savings in steam cycle monitoring and control applications The Right pH Electrode for Steam Cycle Monitoring and Control A steam generating plant requires very clean water and carefully controlled chemistry for proper operation of a boiler that runs [...]
Cyanide Processes Description Cyanide-containing waste is produced in various industries such as mining and electroplating. Processes such as stripping, cleaning, and plating generate wastes that can include metal cyanide complexes with alkaline iron, nickel, zinc, cadmium, copper, silver, and gold. Wastes containing cyanide are required by both US EPA law 40 CFR part [...]
Chlorine, dissolved in liquid, is one of the most effective and economical germ-killers for the treatment of water to make it potable or safe to drink. Chlorine's powerful disinfectant qualities come from its ability to bond with and destroy the outer surfaces of bacteria and viruses. Drinking water chlorination is one of the [...]
