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.

NRC: Conventional Uranium Mills

 · A conventional uranium mill is a chemical plant that extracts uranium using the following process: Trucks deliver uranium ore to the mill, where it is crushed into smaller particles before being extracted (or leached). In most cases, sulfuric acid is the leaching agent, but alkaline solutions can also be used to leach the uranium from the ore.

ISR Mining - Uranium One

ISR mining technology was developed independently in both the Soviet Union and the United States in the mid-1960's. The method was developed to extract uranium from typical roll‐front type deposits (a sub‐type of sandstone uranium deposits) located in water‐saturated permeable sediments that were not suitable for economical conventional mining techniques.

Uranium processing - Canadian Nuclear Association

After mining, uranium ore is transported to a nearby mill for processing. The first step is to crush the ore and mix it with water so that it can move through a series of mill circuits. After crushing, the ore is treated with acid in large tanks, to separate the uranium from other minerals in the rock.
