Copper recovery using leach/solvent extraction

The concept of selectively extracting copper from a low-grade dump leach solution followed by stripping the copper into an acid solution from which electrowon copper hodes could be produced occurred to the Minerals Group of General Mills in the early 1960s.

Hydrometallurgical Process - an overview ScienceDirect

B. Mishra in Encyclopedia of Materials: Science and Technology 2001. 2.4 Hydrometallurgy of Laterite Ores. Two hydrometallurgical processes for the recovery of nickel from oxide ores have been commercialized: the reduction roast–ammonium carbonate leach process and the sulfuric acid pressure leach process for the treatment of low magnesia content laterite ores.

2.1 Hydrometallurgy

The transfer of a metal from the ore to the leach solution constitutes a transfer from a solid to a liquid phase. Because the dissolution is selective most of the unwanted components in the ore are unaffected by the leaching process and remain in the solid

COPPER II EXTRACTION FROM AMMONIA LEACH SOLUTION

Extraction of copper II was performed with the use of chosen extractants diluted in aliphatic diluent Exxsol D80. The concentration of extractants in the organic phase was equal to 10% v/v . The pregnant leach solution from ammonia leaching was used as an aqueous phase. Extraction was performed at ambient temperature. Aqueous A

How Hydrometallurgy and the SX/EW Process Made Copper the

Here the copper is extracted away from the aqueous phase leaving behind most of the impurities that were in the leach solution. Since the copper ion is exchanged for hydrogen ion the aqueous phase is returned to its original acidity and recycled to the leaching step of the process.
