In-Situ Recovery and What Makes It a Great Mining Method

Mining is the process of extracting valuable minerals and other materials from the earth. A popular mining method is open-pit mining, followed by underground mining. In-situ mining, also known as in-situ leaching or In-Situ Recovery, is not often used by miners despite being around for more than 50 years. 

In-situ mining involves the dissolution of minerals, followed by the collection of minerals from below the surface. The method entails low costs and relatively low impact on the environment compared to other more rapidly developing mining methods and processes.

Why Should It Get More Attention?

In-situ mining involves drilling a series of boreholes into an orebody and using acids or bases to dissolve mineral deposits. Water may be added as well to increase efficiency. The dissolved minerals can then be pumped to the surface for collection, leaving behind a large cavity. 

This saves miners the trouble of manually excavating a large space with large equipment to access their resources. Here are some more advantages in-situ mining provides:

1. Environmental Friendliness

Copper mining, in particular, has caused a lot of environmental problems and controversies. However, in-situ mining can be carried out to minimize its impact on the environment with minimal disturbance of the surface. 

In-situ mining is environmentally friendly because it does not require the use of chemical processes or explosives. This also means there will be fewer toxic chemicals used in the mining process and less environmental damage.

2. Cost-Efficiency

The in-situ mining process is also cost-efficient because it does not require as much workforce as traditional mining methods. This is because the technique can utilize existing structures and structures that are created under the ground, to help miners access their ore reserves. In-situ mining is a cost-effective method of extracting valuable minerals and metals.

3. Increased Safety

With in-situ mining, miners have a lower risk of injury or death. This is because there is a reduced need for workers to physically enter the mine. The miners only need to drill into the ore body, not enter it. 

Miners working with in-situ mining can use heavy machinery and other equipment to access the ore body. In addition, this method also reduces the risk of cave-ins, as there is minimal excavating done.

4. Large Resource Sourcing

In-situ mining can extract ore bodies that are previously inaccessible using traditional mining methods. Because mining equipment can be easily lowered into an orebody, and the orebody can then be accessed, miners are not limited to accessing only surface ores. In-situ mining opens up new ways for miners to access their ore bodies and access much larger ore bodies.


There are many reasons why in-situ mining is poised to be the future of mining. It is an environmentally friendly method that is cost-efficient, uses fewer resources, and has a lower chance of causing accidents compared to traditional mining methods. While in-situ mining does have its own set of challenges, it can be a viable method for mining for many years to come.
