Crushed ore in the leach pad. The pregnant leach pond is in the distance. One of the biggest advantages of using leaching is that low grade ores that would be uneconomic to smelt become economic to leach. This is largely due to the much lower energy costs of leaching and also to the lower capital and employment costs of the process.

Leaching Mining Fundamentals

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. The solution that dissolves the ore is then pumped out and processed. Disadvantages of Leaching. Leaching is a
