Uranium mining + milling

2019-11-30  The ore grade is defined as the uranium content of the uranium-bearing rock, usually given as mass-% U 3O 8, or in grams uranium oxide per kg rock. The minimum amount of rock to be mined and milled to obtain 1 kg uranium is inversely proportional to the ore grade. The dilution factor is a simple mathematical relationship

Electrical energy demand for uranium mining, milling

The amount of electrical energy consumed in mining, transporting, and hoisting uranium ore to the surface was empirically calculated as a function of ore depth and production rate. Four mathematical algorithms have been developed as a function of tonnage milled and mill types.

Sustainability of Uranium Mining and Milling: Toward

2008-3-4  In this paper, we compile and analyze a range of data on uranium mining and milling, including uranium resources as well as sustainability metrics such as energy and water consumption and carbon emissions with respect to uranium production—arguably the first time for modern projects.

Uranium tetrafluoride production using the dropping

2021-3-15  The nuclear fuel cycle is the set of associated activities to obtain electrical energy, based on nuclear power plants, or for the production of radiopharmaceuticals in research reactors. The tasks involved in the uranium production start with the extraction of uranium ore and subsequent acid leaching, either in milling operations or near mine sites [ 1,2 ].

A top-down assessment of energy, water and land use

2013-11-1  The direct energy used to mine and mill uranium is below 1% of the electrical energy ultimately produced by the uranium. Even if U demand growth is strong, the direct energy return on investment of U mining and milling will remain well above 1.

Sustainability of Uranium Mining and Milling: Toward

2008-3-4  The mining of uranium has long been a controversial public issue, and a renewed debate has emerged on the potential for nuclear power to help mitigate against climate change. The central thesis of pro-nuclear advocates is the lower carbon intensity of nuclear energy compared to fossil fuels, although there remains very little detailed analysis of the true carbon costs of nuclear energy.
