The solid waste remaining after recovery of uranium in a processing plant are the tailings, consisting of everything that was in the ore except the extracted uranium. The main radioactive materials remaining are those from the uranium decay series, mainly thorium-230 and radium-226.
URANIUM ORE PROCESSING RESEARCH FOR A SUITABLE TECHNOLOGY TO URANIUM “YELLOWCAKE ”PRODUCTION 1963 -1977 many pilot tests were organized for uranium ore processing using samples of ores mined at the Romanian mines works at the pilot processing facility and laboratory in STEI town, within the Bihor branch
Laboratory testing of uranium ores is an essential step in the economic evaluation of uranium occurrences and in the development of a project for the production of uranium concentrates. Although these tests represent only a small proportion of the total cost of a project, their proper planning, execution and interpretation are of crucial importance.
The ore can then be crushed and treated at a mill to separate the valuable uranium from the ore. Uranium may also be dissolved directly from the ore deposits in the ground (in-situ leaching) and pumped to the surface. Uranium mined from the earth is stored, handled, and sold as uranium oxide concentrate (U 3 O 8).

Significant concentrations of uranium occur in some substances such as uraninite (the most common uranium ore), phosphate rock deposits, and other minerals. Natural uranium consists primarily of isotope 238 U (99.28%); therefore, the atomic mass of the uranium element is close to the atomic mass of 238 U isotope (238.03u).

New uranium mine projects might threaten vultures in Namibia. Prospecting and mining for uranium can be added to the list of possible impacts on vultures in Namibia, according to Peter Bridgeford of the Vultures Namibia Organisation. The Namib Desert is the main breeding area of lappet-faced vultures.
Uranium Ore Crushing and Sampling Uranium Ore is hauled by truck to the mill site, where it is weighed and a grab sample taken for moisture. Truck loads from each respective ore supplier are then dumped on a stock lot until 150-200 tons are accumulated at which time it is delivered to a 50-ton receiving hopper for passage through the crushing and sampling plant.

uranium ore processing pilot plant has been achieved through the following stages: (1) Precipitation using sodium hydroxide, (2) uranium selective leaching using sodium carbonate, and (3) uranium oxide precipitation using hydrogen peroxide. About 93% of the raffinate uranium content has been recovered by applying the suggestedflow diagram.
Uranium ore. Uranium ore deposits are economically recoverable concentrations of uranium within the Earth ''s crust. Uranium is one of the more common elements in the Earth''s crust, being 40 times more common than silver and 500 times more common than gold. It can be found almost everywhere in rock, soil, rivers, and oceans.

Ore mined from open-pit and underground mines travels to a conventional mill, where it is crushed, ground and leached to dissolve the uranium. Most of the ore is barren rock or other minerals that are not dissolved in the process. These solids, also called tailings, are separated from the uranium solution, usually by allowing them to settle out

For use in light water reactors, the uranium ore concentrate is refined (purified) and converted to uranium hexafluoride (UF 6) in a conversion plant. At the enrichment plant, the concentration of the fissile uranium isotope U-235 in the uranium hexafluoride is raised from its natural grade of 0.711% to the range of 3
