The Commission and experts from the member states have examined the state of research and development in uranium exploration and uranium ore processing. The conclusion is that although considerable research has been undertaken in these fields, especially during the early 1960's, only limit~d work has been carried out since in the

At conversion facilities, uranium ore concentrate is processed to create uranium hexafluoride (UF 6 ), which is the feed for enrichment, or uranium dioxide (UO 2) which is the feed for natural uranium fuel fabrication (e.g. for heavy water reactors).

Geology Notes

This type of magmatic differentiation is particularly active in large basaltic magmas where chromite (ore of chromium), magnetite, and platinum are occasionally generated. The majority of hydro- thermal deposits originate from hot, metal-rich fluids that are remnants of late-stage magmatic processes. During solidification, liquids plus various

First production from restarted Canadian operations

McArthur River commenced production in 1999. High-grade ore 600 metres underground is mined using methods including remote control raise boring. The ore is then trucked 80 km south to be milled at Key Lake, itself the site of a former uranium mine. The restarted operations are expected to produce up to 2 million pounds U3O8 (769 tU) this year.

Uranium – 235. f URANIUM ORE ENRICHMENT To increase the amount of Uranium 235 in the ore, the ore is firstly enriched. In the process, the ore is reacted with fluorine to form Uranium fluoride. The fluoride would contain molecules of U – 238 fluoride and U – 235 fluoride. The fluorides are then separated by a filtration process.

Uranium:

The process used to increase the amount of uranium-235 relative to uranium-238 is known as uranium enrichment. U.S. civilian power plants typically use 3 to 5 percent uranium-235. Weapons use "highly enriched uranium" (HEU) with over 90 percent uranium-235. Some research reactors and all U.S. naval reactors also use HEU.

World Nuclear Association

06.08.2008Initially Mecsek's uranium ore was shipped to Estonia for milling, but from 1963 it was milled on site and concentrate exported to the Soviet Union. A total of about 21,000 tU was produced at an average recovery of 50-60%. Since 1997 the mine has been decommissioned and remediated at considerable expense (about $170 million).

Uranium Processing

Uranium ore is crushed and processed in uranium mills, located at or near the mines, to extract uranium using chemical processes. A fine powder, called yellowcake, is the resulting uranium concentrate product and is packed in 55 U.S. gallon ring-sealed drums containing approximately one-half tonne of yellowcake.

How is Uranium Produced?

The uranium ore is blasted and the resulting debris transported to the surface. After both open-pit and underground mining, the uranium ore concentrated in the extracted rocks is weak, usually only around 0.3%. The rocks are crushed to a fine powder and added to water to create a slurry.

Uranium mining in the Bancroft area
