The milling (refining) process extracts uranium oxide (U 3 O 8) from ore to form yellowcake, a yellow or brown powder that contains about 90 percent uranium oxide. [6] Conventional mining techniques generate a substantial quantity of mill tailings waste during the milling phase, because the usable portion is generally less than one percent of ...

Uranium is extracted from ore at uranium mills and at in situ leach (ISL) facilities. Uranium is also obtained as byproduct from nonconventional uranium plants, like the phosphate industry. Mining and milling generate waste rock, sludge, tailings (dried sludge), wastewater and leached areas.

Pyongsan Uranium Mine and Mill. Pyongsan is believed to the most important uranium mine and mill in North Korea. (The other mill, near Pakchon, was described as a pilot facility.) Commercial satellite imagery from Digital Globe and Airbus Defense and Space show the layout of the mine and mill that turns uranium ore into yellowcake.

The well feed contained 150 mg/1 uranium, which corresponds to a uranium loss of 245 kg (540 lb)/day. At present values of yellow cake, this would have a market value of 8,100 to 10,800/day. This uranium could be recovered by the instal lation of an ionexchange plant between the .

Geocache Description: From 1930 to 1942, the company purified Uranium ore. The mill was in Pennsylvania in stead of Colorado (which would have been closer to the mines that produced the carbonite) because the processing of the ore required huge quantities of chemicals; these chemicals were available in Pennsylvania.

Milling produces a uranium oxide concentrate, which is shipped from the mill. In the milling process, uranium is extracted from the crushed and groundup ore by leaching, in which either a strong acid or a strong alkaline solution is used to dissolve the uranium oxide.
