Solvent extraction process to recover Copper from an aqueous feed containing copper and Iron, through the stages of extraction, and electrowinning retroextraccion,That before the stage of retroextraccion the loaded Organic phase is washed with an aqueous acid Solution which has been contacted with Metallic Copper.

摘要

An improvement in the process of solvent extraction to recover metal values, or CopperFrom acidic Aqueous Solutions containing copper and Iron, and can also include Chloride,And more particularly to an improvement that provides reasons increased Copper to iron in the loaded Organic Phase extractant.The Improvement comprises washing the loaded Organic extractant phase before retroextraer Copper values from the same,Acid washing with an aqueous solution containing at least a portion of the electrolyte solution has been previously contacted with Metallic Copper.
