  • (PDF) Industrial Application of Ammonia Assisted Cyanide ...

    Before the introduction of the agitation leach plant, when only heap leaching was used at Gedabek, the copper content of the ore was not a serious problem. In spite of the fact that much of the copper in the upper levels of the mine was in the form of oxide and carbonate minerals, which are highly soluble in cyanide solutions, the concentration of copper in the heap leach solutions was typically around 1 g/l Cu.

    The solution flows through cracks in the rock under pressure, leaching the copper from the rock into the solution. The solution is then pumped to the surface to recover the copper, using solvent extraction techniques. Tests show that recovery rates normally achieved with heap and dump leaching could also be approached with in situ mining.
