Use of weak acids or polioxigenados Oxygenated compounds or Derivatives, Minerals, which generate in the processes of electrowinning of copper cathodes or anodes of electrolytic cells, from the leaching of a Copper Ore

摘要

The Invention relates to the use of weak acids or polioxigenados Oxygenated or minerals or compounds that generate, to stabilize and improve its buffer electrolyte conductivity, and / or catalytically to promote the electrowinning of Copper.It also describes a procedure of electrowinning Copper comprising adding a required amount of a weak acid or polioxigenados Oxygenated or a compound or a Mineral that generates the electrowinning process; where the amount of the weak acid depends on the Characteristics of the Ore, the electrolyte and current Density used.In the present Invention, the addition of weak acids or polioxigenados Oxygenated compounds or Derivatives, Minerals, which generate, loaded from the electrolyte phase extraction with solvents and entering the stage Electrowinning (EW) aims to homogenize The current density in the electrolytic Cell,Resulting in an increase in the efficiency of energy consumption versus amount of Copper deposited
