Heap Mining Efficiently Leaches Lower Grade Gold from S

The then enters the heap and leaches the gold. Gold loves Once the leach solution dissolves the gold, it continues percolating through the lower lifts until it reaches the liner located underneath the heap. Then it drains into a storage pond. Most economical heap leach mines achieve 70-80% recovery of gold and 30-50% of silver.
