Why Should Mining Companies Practice In Situ Recovery?

Health and safety are common issues faced in the mining industry until today. However, in-situ recovery (ISR) —a mining process involving injecting a leaching solution into the ore body to extract metals—working on excavations becomes safer and less risky. But how does in-situ recovery change the practices of the mining industry?

Here are some reasons modern mining companies are making the shift:

1. Prevents Acid and Metal Leaching

Acid and metal leaching are common problems in the mining industry. Acid leaching is the process of dissolving metals in acid. On the other hand, metal leaching is the process of dissolving metals in water. Both methods can contaminate water resources and cause health problems for workers.

In-situ recovery prevents these problems by keeping the leaching solution within the ore body. The leaching solution dissolves the rock’s minerals, is pumped out of the holes, and collected. In-situ recovery has several advantages over traditional mining methods.

2. Uses Smaller Driller Techniques

In-situ recovery (ISR) is a mining method that involves extracting uranium from underground deposits without having to remove the overlying rock. The process uses smaller drills, providing more advantages than larger-diameter drills.

Smaller drills are cheaper, faster, and cause less environmental damage. They require less energy to operate and generate less waste. Due to their size, they also allow for more precise drilling, which can be critical in some applications.

3. Leaves the Water Table Undisturbed

In-situ recovery leaves the water table undisturbed. In contrast, conventional mining methods require digging a large pit and removing the topsoil and rock. It exposes the water table to the surface, resulting in water pollution.

Meanwhile, in-situ recovery has several advantages over conventional mining methods. It is less intrusive and can be used in areas where traditional mining is impossible. This minimal surface disturbance is beneficial in sensitive ecosystems, preventing environmental damage.

4. Takes Less Time

In-situ mining takes less time than conventional mining. For example, mining uranium with in-situ can take as little as two years. Meanwhile, mining uranium conventionally takes up to 20 years, taking up too much time and producing environmental damage over the years.

The reduced time frame is due to the lack of surface disturbance. Minimal surface disturbance means minimal time spent on site, reducing the overall time of the mining project. In-situ mining is a more efficient mining method.

5. Sustainable Mining Method

The method is environmentally friendly, producing fewer emissions and less waste. It is also more effective in terms of how it affects various aspects of the mining process.

In-situ recovery is the most efficient modern mining method and is also sustainable enough that mining companies can use it continuously without damaging the environment.


Finding other ways to improve the mining industry includes trying newer methods. In-situ recovery is not a new approach, but it offers a more sustainable way to retrieve the elements from a site while being environmentally friendly.

In-situ recovery also can be more efficient, as it doesn’t require mining quantities of rock to get to the minerals. Therefore, mining companies should learn more about in-situ recovery and switch to it as soon as possible.
