Uranium Mining in South Africa

Mining Process The techniques of extraction for uranium mining are proportionate as follows: In-situ leach (44.9%), underground mining (26.2%), open pit (19.9%) and heap leaching (1.7%), with the remaining 7.3% arising as a result of byproduct from other mining operations. [3]

The Health and Environmental Impact of Uranium Mining

However, the process of obtaining Uranium through mining and processing ore also poses serious risks to people and the environment. To complicate these issues further, historically in the United States and around the globe the negative impacts of Uranium mining have fallen disproportionately on low income and minority communities. [2]

The Health and Environmental Impact of Uranium Mining

Surface mining or open-pit miningdepends on the removal of all surface soil and rock covering the desired Uranium. While it is safer for the miners than underground mines since they are not exposed to roof-falls or pneumoconiosis, it blasts 30 times more topsoil than Uranium

Uranium mining at Jabiluka | naa.gov
