Uranium mining is the process of extracting uranium ore from the ground. The most common methods of mining uranium involve open-pit mining, underground mining, and in-situ leaching. Open-pit mining involves removing the surface layers of soil and rock to access the ore deposits below. Underground mining involves digging tunnels and shafts into the earth to reach the ore deposits. In-situ leaching involves pumping a solution into the ore deposits to dissolve the uranium and then pumping the solution out to be processed.
