Uranium mines and mills waste. The main types of waste generated by the mining and milling of uranium ore are tailings and waste rock. Tailings are the waste produced by grinding the ore and the chemical concentration of uranium. When dried, tailings have the consistency of fine sand. Waste rock is simply rock material removed from the mine to ...

Largescale extraction of uranium from auriferous ore only took place during the cold war, leaving tailings with high uranium concentrations that were deposited before and after this period. Recent studies found elevated levels of the radioactive heavy metal in groundwater and streams, mainly attributed to the discharge of contaminated water from mines.

Environmental Impacts of Uranium Mining Environmental Impacts of Uranium Mining

Environmental Impacts of Uranium Mining

Uranium ore is generally processed through grinding the ore materials to a uniform particle size, which is then treating through chemical leaching to extract the uranium. This results in a dry powder form of the natural uranium commonly referred to as "yellow cake." [2] The waste products of this process are called mill tailings, sandy waste that contains heavy metals, Radium, and other ...

Tailings from the ore processing must be placed in engineered dams or underground. Finally the whole site must be rehabilitated at the end of the project. Meanwhile air and water pollution must be avoided. These processes are common to all metalliferous mining, and are well recognised and understood. In the case of in situ leach (ISL) mining, there is much less disturbance – simply multiple ...

Uranium Mining Impacts in the Grand Canyon Region

Even for highgrade deposits, uranium ore is typically comprised of < 1% elemental uranium by volume. Thus, additional chemical processing—milling—of the ore material must take place. Historically, milling operations in the Grand Canyon region took place at, or near, the mine site to minimize transport costs. The milling process typically ...
