Heap Leaching - an overview | ScienceDirect Topics
Low-grade ore was processed using the heap leaching technology. The heaps were arranged on two sites on which approximately 7.2 million tons of low-grade ore have been treated. After the termination of uranium production, wastes from Heap Leaching Site I (next to the mill) have been relocated to WRP III (2.2 million tons) as the first step ...
