C) Placer Mining, Mountaintop Removal, Shaft Mining, Drift Mining
D) Cyanide Leaching, Acid Leaching, Solvent Extraction, Roasting

Answer 1

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:

1. 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.
2. Underground Mining: This method is used for deeper deposits where the ore is accessed through tunnels and shafts.
3. 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.
4. 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.
