Dual Leaching Method for Recovering Silver and

Heap leaching is an important method for recovery of gold, silver, and copper. These leaching technologies have the ad vantages over conventional mining of lower capital and operating costs, shorter startup times, and environmental and safety improvements. Thus, in situ or heap leaching is a favorable method
