Uranium - Wikipedia

Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table.A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons.Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and …

Conventional Uranium Mills | NRC.gov

(In addition to extracting 90 to 95 percent of the uranium from the ore, the leaching agent also extracts several other "heavy metal" constituents, including molybdenum, vanadium, selenium, iron, lead, and arsenic.) The mill then concentrates the extracted uranium to produce a material, which is called " yellowcake " because of its yellowish color.

From ore to yellow cake - Frontline

The ore extracted from a mine is processed to yield yellow cake, or uranium in a compound form, in a processing plant. The ore is first crushed to a uniform particle size, and the fine ore is then subjected to chemical leaching. The extracted yellow cake is transported to the Nuclear Fuel Complex in Hyderabad, where it is fabricated into fuel ...

Fact Sheet on Uranium Recovery | NRC.gov

Uranium recovery focuses on extracting natural uranium ore from the earth and concentrating (or milling) that ore. These recovery operations produce a product, called "yellowcake," which is then transported to a succession of fuel cycle facilities where the yellowcake is transformed into fuel for nuclear power reactors.

Conventional Uranium Mills | NRC.gov

Conventional milling is one of the two primary recovery methods that are currently used to extract uranium from mined ore. 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).

Uranium Mining and Milling Wastes: An Introduction

Ore mined in open pit or underground mines is crushed and leached in a uranium mill. A uranium mill is a chemical plant designed to extract uranium from ore. It is usually located near the mines to limit transportation. In the most cases, sulfuric acid is used as the leaching agent, but alkaline leaching is also used.
