Two gold heap leach operations in Zimbabwe SpringerLink

Synopsis. Anglo American Corporation has commissioned two gold projects in Zimbabwe since Independence, both utilising heap leach technology. This technique has enabled these relatively low grade, low tonnage properties to be economically developed; something which may not have otherwise been possible by more capital intensive routes.
