Process for extracting and recovering copper |
| abstract |
A process for extracting and recovering copper from an aqueous solution containing copper values comprising: (a) contacting the aqueous copper bearing solution with an organic phase comprising a water insoluble and water immiscible solvent solution of an extraction reagent formulation to extract at least a portion of the copper values into the organic phase; (b) separating the resultant copper pregnant organic phase from the copper baren aqueous phase; and (c) recovering the copper values from the copper pregnant organic phase; wherein the extraction reagent formulation comprises (i) an oxime extractant and (ii) an equilibrium modifier in which the modifier is a linear diester or polyester of an unbranched dicarboxylic acid and an unbranched alcohol. |
