Voltamperometric analysis of the reductive decomposition of chalcopyrite acetic acid-water system
In this work, an electrochemical analysis of the reduction of chalcopyrite is presented using an aqueous medium in the presence of a weak acid such as acetic acid, in order to find the most favorable energetic conditions to dissolve the iron contained in the chalcopyrite and thereby reduce...

En este trabajo se presenta un análisis electroquímico de la reducción de calcopirita empleando un medio acuoso en presencia de un ácido de carácter débil como el ácido acético, con el fin de encontrar las condiciones energéticas más favorables para lograr disolver el hierro que está contenido en la calcopirita, y con ello aminorar el fenómeno de pasivación. La investigación se realizó a nivel microelectrólisis, analizando diferentes variables como la concentración del electrolito, conductividad del electrolito y potencial sobre la cinética de reducción de la calcopirita. Este estudio se complementó con una caracterización de la superficie de la calcopirita reducida mediante la técnica de FESEM y con una cuantificación del hierro que se libera en la solución de las polarizaciones catódicas más importantes.

In this work, an electrochemical analysis of the reduction of chalcopyrite is presented using an aqueous medium in the presence of a weak acid such as acetic acid, in order to find the most favorable energetic conditions to dissolve the iron contained in the chalcopyrite and thereby reduce the passivation phenomenon. The investigation was carried out at the microelectrolysis level, analyzing different variables such as electrolyte concentration, electrolyte conductivity and applied potential on the chalcopyrite reduction kinetics. This study was complemented with a characterization of the surface of the reduced chalcopyrite using the FESEM technique and with a quantification of the iron that is released in the solution of the most important cathodic polarizations. |
