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 [...]
Abstract - This white paper explores how unique design features and iodide/triiodide ion pair reference chemistry help Thermo ScientificTM OrionTM ROSSTM pH electrodes deliver fast, stable and accurate measurements. When pH measurement performance counts - A pH measurement, along with temperature and weight, is one of the three most common measurements performed in laboratories. Reliable and accurate [...]
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 [...]
