Mined uranium ore cannot be used directly to power a nuclear reactor; it needs to be processed and enriched in order to be used for energy.The ore is first brought to a mill where it is converted into U 3 O 8, an isolated form of uranium referred to as "yellowcake".Most power plants cannot use the fuel in this form yet, since the content of the fissile isotope of 235 U is only about 0.7%.

It was there the Commission built a uranium ore processing plant in 1955. The Weldon Spring Uranium Feed Mill Plant, operated by Mallinckrodt Chemical Works of St. Louis, processed raw uranium ore into "yellow cake," or concentrated ore which was shipped to other sites. The processing plant operated until 1966.

The largest underground uranium mine on Navajo and Hopi lands operated from 1979 to 1990. The worst nuclear accident happened at Uranium Mill, which is south of the Navajo Reservation. More than 1,000 open-pit and underground uranium mines on the reservation are abandoned, unreclaimed, and highly radioactive.

Yellowcake. The solid form of mixed uranium oxide, which is produced from uranium ore in the uranium recovery (milling) process. The material is a mixture of uranium oxides, which can vary in proportion and color from yellow to orange to dark green (blackish) depending on the temperature at which the material is dried (which affects the level of hydration and impurities), with higher drying ...

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 radioactive contaminants. [3] As the Radium decays over time in these piles, they release Radon, a highly radioactive gas.

Here's the recipe for yellowcake as prepared in the Orano mill. Start with high-grade uranium ore that has already been crushed. Leach it, oxidize it and decant it before clarifying it. Add solvents, then precipitate this mixture. The result is a yellow solution called yellowcake. Put it in an 800°C oven and bake until it is a grey powder ...

Nuclear energy, which provides 22 percent of the nation's electricity, requires enriched uranium to fuel nuclear reactors. Following mining, uranium ore is sent to a mill where it is chemically treated to extract uranium oxide (U~08), more commonly known as "yellow cake." Uranium oxide contains two primary isotopes: '5U and 'EU.
