This condition decreases the copper extraction rate and may eventually produce a dormant dump that may leave much undissolved copper within the ore bed. In addition to iron dissolved from the ore during leaching, iron derived from the cementation step may significantly contribute to the plugging of a leach dump. The newer solvent extraction-electrowinning method recovers copper from leach ...
