Thermodynamic stability diagram for the copper/water/amylxanthate floatation system
Keywords:
Eh-pH diagram, xanthate, copper amylxanthate, copper, ionic flotation.Abstract
The objective of the investigation was to develop a thermodynamic stability diagram which characterizes the copper/water/amylxanthate flotation system as part of the theoretical fundamentation needed to analyze the copper ions flotation process using potassium amylxanthate as flotation collector reagent. Using the main chemical reactions of the system and with the assistance of the Medusa software the Eh-pH diagram was obtained in which the stability zones were defined for the different chemical species in order to analyze the flotation process of copper ions with amylxanthate collector reagent. It was established that thexantogenated species of cupper (I) and (II) co-exist within the pH range of 4 to 13. This ratio decreases as the pH increases.Downloads
