As a result of the high levels of soluble copper in the cleaner tailings streams, cyanide consumptions were very high, but copper was notably extracted to the leach liquor. This extraction result suggests that the leach liquor is a good candidate for the SART process, which can recover copper as a precipitate and regenerate cyanide for recycling.
