Popis:	The configuration of a CYANEX 272 solvent-extraction plant can vary significantly depending on the composition of the pregnant leach solution. Parameters such as the organic-to-aqueous flowrate ratio, the extractant concentration, the pH profile, and the number of stages must be optimized for the given feed conditions. MINCHEM is a modeling program that was specifically designed by Cytec Industries Inc. to allow a rapid assessment of these parameters. The software was used in the present study to determine the optimum pH profile and stage requirements for the extraction and scrubbing circuits of a hypothetical cobalt/nickel plant using CYANEX 272 extractant. The simulations were completed to maximize cobalt recovery from the feed and minimize both impurity transfer in the loaded organic phase and the need for cobalt reprocessing from the scrub stage.
