Uranium is a naturally occurring element that is present in air, water, soil, rocks, plants, and animals. It is a weakly radioactive substance. Depleted Uranium (DU) is a by-product of uranium processing. DU is what remains after some of the more radioactive components (called isotopes) are removed from natural uranium for use in nuclear fuel.

Therefore, a number of chemical and physical separation processes are required to convert uranium ore into optimized nuclear fuel elements through the stages of mining, milling, …

Uranium mining and milling produces very large amounts of waste, primarily in the form of excavated rock, ores that contain too little uranium to be profitable and mill tailings. Mill tailings are produced during the processing of uranium ore. They are sand-like, crushed rock residues, which are left over after the uranium has been extracted. The

Uranium Milling and Processing. Once the ore is mined, it is typically milled on site into a uranium oxide concentrate, often known as "yellowcake". In the milling process, uranium is extracted from the crushed and ground-up ore by leaching, in which either a strong acid or a strong alkaline solution is used to dissolve the uranium oxide. ...

Uranium is the primary fuel for nuclear power generation. To a very much greater extent than for other fuels to produce electricity it must undergo processing both at the mine and subsequently to ...

Uranium is the basis of the nuclear power industry as well as military weapons programs. The unique position of uranium in these activities, the increasing ore grades that have been discovered, and increasing environmental concerns have very much influenced recent process developments. This article presents a review of the current status of uranium processing.

This paper serves to present the results from the integration of a nano-filtration system at the Muyumkum satellite processing plant. The project consisted of screening …

This publication is one of a series of Technical Reports on uranium ore processing that have been prepared by the Division of Nuclear Fuel Cycle and Waste Management at the IAEA.

•Mechanical process using kinetic energy and water to force ore grains against each other through opposing nozzles. •Removes uranium in coatings and interstitial deposits. •The fines commonly contain a high percentage of the uranium, and can be separated by screening into a high-grade, low-volume, concentrate.
