LeachingMining Fundamentals

Heap leaching is carried out in the extraction of copper, nickel, uranium and precious metals. Insitu Leaching. Insitu leaching is also known as insitu recovery, or solution mining. This is especially used to extract copper and uranium. In this process, holes are drilled into the ore deposit by explosive or hydraulic fracturing methods. The leaching solution is then pumped through these channels.
