Uranium Mining and Milling Wastes: An Introduction
Considering the actual period of time the hazards from uranium mining and milling wastes persist, these regulations are of course only a compromise, but they are a first step, at least. Regulations for the protection of groundwater were not included in the initial legislation; they were only promulgated in January 1995.

Most of the uranium ore deposits at present supporting these mines have average grades in excess of 0.10% of uranium – that is, greater than 1000 parts per million. In the first phase of uranium mining to the 1960s, this would have been seen as a respectable grade, but today some Canadian mines have huge amounts of ore up to 20% U average grade.

Conventional Mining | Uranium Producers of America
CONVENTIONAL MINING AND MILLING OF URANIUM ORE Introduction. Production of uranium concentrates, in the form of U3O8, or "Yellowcake" as it is commonly referred to in the industry, from ore which is mined by open pit or underground methods and processed to recover uranium, employs technology and methods common to the mining industry.
Dasa Uranium Project, Republic of Niger
The Dasa uranium project is an underground, high-grade uranium mine being developed by Global Atomic in the Republic of Niger. The project was initially envisaged for open-pit operations followed by underground mining after reaching a certain depth with a preliminary economic assessment (PEA) for the open-pit project announced in 2018.
AUSTRALIA'S URANIUM MINES – Parliament of Australia

One advantage uranium mining has over production methods used to retrieve fossil fuels is that plants need much less uranium to create electricity than is required if using coal, natural gas or oil. One kilogram of uranium provides the same amount of energy as about 100,000 kilos of oil or nearly 220,000 kilos of coal.
