Diagrama de estabilidad termodinámico del sistema de flotación cobre/agua/amilxantato

Beatriz Ramírez-Serrano, Alexis Otero-Calvis, Alfredo Coello-Velazquez

Resumen


El propósito del trabajo fue obtener el diagrama de estabilidad termodinámico que caracteriza al sistema de flotación cobre/agua/amilxantato, como parte del fundamento teórico necesario para el análisis del proceso de flotación de iones cobre con el reactivo colector de flotación amilxantato de potasio. A partir del sistema de reacciones químicas fundamentales y con ayuda del sofware Medusa se obtuvo el diagrama Eh-pH en el cual se definen las zonas de estabilidad de las diferentes especies químicas y se establece que en el rango de pH de 4 a 13 coexisten las especies xantogenadas de cobre(I) y (II) cuya relación disminuye con el incremento del pH.

Palabras clave


diagrama Eh-pH; xantato; amilxantato de cobre; cobre; flotación iónica
