Final answer:
The main methods of extraction of Uranium ore are open-pit mining, underground mining, in-situ leaching, and heap leaching.
Step-by-step explanation:
The main methods of extraction of Uranium ore are:
- Open-pit Mining: This involves the removal of overlying soils and rock to access the ore beneath the surface. It is commonly used for shallow deposits.
- Underground Mining: This method is used for deeper deposits where the ore is accessed through tunnels and shafts.
- In-situ Leaching: Also known as solution mining, this method involves injecting a leaching solution into the ore deposit to dissolve uranium. The uranium-rich solution is then pumped to the surface for further processing.
- Heap Leaching: In this method, the ore is stacked in large heaps and a leaching solution is applied to extract the uranium. The solution is collected and processed to recover the uranium.
