Abstract
La invencion se refiere al uso de acidos debiles oxigenados o polioxigenados o minerales o compuestos que los generen, para estabilizar y tamponar el electrolito mejorando su conductividad, y/o para promover cataliticamente la electrodepositacion de cobre. Tambien se describe un procedimiento de electro obtencion de Cobre que comprende adicionar una cantidad necesaria de un acido debil oxigenado o polioxigenados, o un compuesto o un mineral que lo genere, al proceso de electrodepositacion; donde la cantidad necesaria del acido debil dependera de las caracteristicas del mineral, del electrolito y de la densidad de corriente utilizada. En la presente invencion, la adicion de acidos debiles oxigenados o polioxigenados, minerales, compuestos o derivados que lo generen, a los electrolitos cargados que vienen desde la fase de extraccion con solventes y que ingresan a la etapa electro obtencion (EW), tiene como finalidad de homogenizar la densidad de corriente dentro de la celda electrolitica, dando como resultado un aumento en la eficiencia de consumo de energia electrica versus cantidad de cobre depositadoThe invention relates to the use of weak oxygenated or polyoxygenated acids or minerals or compounds that generate them, to stabilize and buffer the electrolyte by improving its conductivity, and / or to catalytically promote the electrodeposition of copper. Also described is a process for the electrowinning of Copper that comprises adding a necessary amount of a weak oxygenated or polyoxygenated acid, or a compound or mineral that generates it, to the electrodeposition process; where the necessary amount of weak acid will depend on the characteristics of the mineral, the electrolyte and the current density used. In the present invention, the addition of weak oxygenated or polyoxygenated acids, minerals, compounds or derivatives that generate them, to the charged electrolytes that come from the extraction phase with solvents and that enter the electrowinning stage (EW), has as purpose of homogenizing the current density within the electrolytic cell, resulting in an increase in the efficiency of electric power consumption versus the amount of copper deposited
