heap leaching for copper ore strong ability

  • The use of surfactants to aid and improve the leaching of

    Work was performed with surfactants developed by BASF specifically for heap leaching. Initial experimentation consisted of using flooded vats to compare copper extraction from ores. Leach solution with and without surfactant was fed to the ores. The presence of surfactants was noted to increase the overall copper recovered by approximately 2 3%.
