Uranium is a naturally occurring radioactive element used for fuel in nuclear power reactors. Canada, one of the world's largest uranium producers, accounts for 18 percent of global production and exports 90 percent of its uranium. Uranium is mined so it can be processed at a milling facility in order to recover the uranium concentrate.

Uranium mines and mills waste. The main types of waste generated by the mining and milling of uranium ore are tailings and waste rock. Tailings are the waste produced by grinding the ore and the chemical concentration of uranium. When dried, tailings have the consistency of fine sand. Waste rock is simply rock material removed from the mine to ...

Uranium ore concentrate (UOC) is a general term to describe the final product of uranium mining and milling, although the term "yellowcake" is still loosely used. In fact, UOC may be yellow (eg, ammonium diuranate, uranyl peroxide), dark green-black, grey (U 3 O 8),, and sometimes orange. Download : Download full-size image; Figure 6.8.

Milling and processing. Conventional mines have a mill where the ore is crushed and ground to liberate the mineral particles, then leached in tanks with sulfuric acid to dissolve the uranium oxides. The solution is then processed to recover the uranium. With some South African uranium recovery from gold tailings, a pressure leach is necessary.

First off, though, the milling stages: Grinding. You have to grind up the rock. Pre-leaching & thickening. A fancy way of saying you need to treat the ground-up rock with acids, and then thicken the slurry. Leaching. Add more caustic substances to the mix to dissolve the coveted minerals. Uranium recovery.

During milling the uranium bearing ore is initially crushed (if preceded by conventional mining), which is typically a dry process, and then ground into a slurry, which is a wet process. The intent of crushing and grinding is to effectively increase the surface area to volume ratio of the material, which facilitates chemical leaching.

While each uranium mill is specifically designed to process the exact source ore being milled, the general overview remains fairly consistent. After mining, ores containing uranium pass through a circuit of processes that includes crushing and grinding, followed by a series of chemical treatments and filtration to remove undesirable materials ...

At the mill, uranium ore undergoes a variety of changes to turn it into a finished product: uranium powder, also known as yellowcake.. The milling process is so important that the U.S. Atomic Energy Commission has helped mines establish mills close by to make it easier to process uranium ore and quicken the production of yellowcake [source: Amundson].
