Voltammetry is suitable in particular for laboratories (as is the case in the mining industry), in which only a limited number of different parameters need to be controlled. Thus, it is often used for specific applications that are either not feasible or too costly using other techniques. Voltammetry can be used in the cen tral analytical lab, but is also often installed in the plant for fast and efficient process control.

The zinc electrolyte used contains and, as a result, minimize interferences of the metal heavy metal impurities coming from the processed zinc deposition in the electroplating process with the required ore.

With the on­line process analyzers from Metrohm Applikon this is possible 24 hours a day, 7 days a week. Metrohm Applikon on­line analyzers are used directly onsite, as close as possible to the process, and run completely stand­alone without any operator intervention required. Metrohm Applikon analyzers are based on wet­chem ical analysis techniques such as titration, photometry, or ionselective electrode measurements. Analyzers are available for single method, single­stream purposes as well as for multiple methods in multiple sample streams. Sampling In on­line analysis, sampling and sample preconditioning are at least as important as the analyzer itself. Metrohm Applikon has a lot of expertise in this area and offers custom­made sampling systems, for example, for pressure reduction, blow back filtering, and settlers for solid separation. All Metrohm Applikon analyzers are equipped with possibilities for discrete digital I/O as well as analog outputs. Results, for example, can be transferred via 4...20 mA out puts, where as alarms and analyzer status can be trans mitted via digital outputs. Digital inputs, in turn, can be used for remote start­stop and sample override purposes. The option is now available for data communication by ModBus/Web Service over ethernet for a complete industrial protocol package. The ADI 2045TI represents the latest generation of wet chemical analyzers. Its modular wet part gives the ADI 2045TI flexibility to adapt it to any specific application. 17 Application examples Hydrometallurgical process: free & WAD cyanide in a gold leach slurry In gold mining, cyanidation (cyanide leaching) is a major A more recent requirement is to measure WAD Cyanide chemical step to extract gold from low grade ore as part (weak acid dissociable metal­cyanide complexes) in addiof the CIP/CIL plant circuit and gold recovery process. tion to Free Cyanide.
