Uranium is extracted as U3O8, an oxide known as yellowcake.
Uranium may also be present in water as the UO22+ uranyl cation.
Most uranium is U-238, which has a half-life of 4.5 billion years.
---------
Uranium has about 200 minerals. See for some examples: http://www.webmineral.com/chem/Chem-U.shtml
The yellowcake is the ammonium diuranate (NH4)2 U2O7 (yellow colour); U3O8 (triuraniumoctaoxyde) is black.
Uranium is a chemical element, natural, radioactive, solid, metal.
What else can I help you with?
What is Uranium's Natural State?
Uranium is usually found in nature in the form of uranium ore, which is a combination of uranium, oxygen, and other elements. It can take the form of minerals such as uraninite, coffinite, and carnotite.
What is uranium 235 when added to natural uranium?
When uranium-235 is added to natural uranium, it increases the overall percentage of uranium-235 in the mixture. This can make the uranium more suitable for use in nuclear reactors or weapons, as uranium-235 is more fissile (more easily split by neutrons) than uranium-238.
What is the ratio of uranium isotopes U-238 to U-235 in natural uranium?
Concentration of 238U in natural uranium: 99,2742 % Concentration of 235U in natural uranium: 0,7204 % The ratio 238U/235U is 137,804.
What is cost of uranium?
Depending very much on the chemical or physical form, purity, enrichment, etc.For nuclear grade powder of natural uranium dioxide: ca. 100 $/kg.
Is uranium 238 a natural element?
yes, it was formed in supernova explosions that occurred before the formation of the solar system
How the plutonium is form by natural uranium?
plutonium can only form from uranium in a nuclear reactor. since the last natural reactors on earth shut down about 3 billion years ago (oklo) it can't happen naturally now.
What is uranium - 235 when added to natural uranium?
Natural uranium has approx. 0,7 % 235U; uranium with more than 0,7 % 235U is an enriched uranium.
Is uranium a natural element?
Yes, uranium is a natural but radioactive element.

Is uranium a base?
Uranium is a natural, radioactive metal.
What is the percentage of uranium-235?
Uranium-235 is an isotope of uranium making up about 0.72% of natural uranium.
How do humans use uranium in the natural environment?
Uranium is a possible polluting agent of the natural environment.
Is depleted uranium 40 percent more radioactive than natural uranium?
Depleted uranium is approx. 60% less radioactive than an equivalent mass of natural uranium.
What is cost of uranium?
Depending very much on the chemical or physical form, purity, enrichment, etc.For nuclear grade powder of natural uranium dioxide: ca. 100 $/kg.
What does uranium costs per 100 gram?
US $ 51,5/lb (at 25.07.2011) or 11,3 USA $ per 100 grams (natural uranium in the form of the unrefined oxide U3O8).
