MODULAR RECOVERY PLANTS

The heap was an accumulation of ore from an on-off heap leach formerly operated by a large international mining corporation, Billiton. Based on an evaluation of exploration drillholes into the heap, KCA was able to show that washing would mitigate an environmental problem (high residual cyanide) and recover significant amounts of gold and silver.
