Leaching an overview ScienceDirect Topics
Heap leaching, however, has a lower yield than conventional methods (10 to 20% less) and recovers a smaller net amount of uranium. Leaching efficiency can be improved by heating leach or wash solutions but the cost of heating a large heap using conventional heat sources would be prohibitive.

MODULAR AND SITEBUILT RECOVERY PLANTS kcareno
The heap was an accumulation of ore from an onoff 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.
