Uranium has a half life of 5,600 years. After that period, one half of the uranium becomes lead. That is why lead is found in uranium deposits.

What country is actinium found in?
Actinium is found in extremely low concentrations in residues from uranium ores (uraninite, pitchblende).
Where are ores found?
Mined of metal ores depend on the position of the metal in electrochemical or activity series but metals can be extract through electrolysis and reduction process.
How uranium is stored in nature as it radioactive element?
Uranium exist in nature as minerals and ores; more than 200 uranium minerals are known today.
What are the common ores of iron and lead?
Common Ores of Lead would be: Galena, which contains 86 percent metal...Anglesite, which carries 68 percent metal...Cerussite, which contains 77 percent metal...Pyromorphite,Mimetite and Wulfenite. Common Ores of Iron would be: Hematite (Hematite deposits are the most important source of Iron Ore in the United States.) Limonite,and Magnetite
How much of the Earth is plutonium?
Plutonium is an artificial chemical elements.
Does Denmark have sizable deposits of uranium?
Denmark is not reported as having uranium ores deposits. Possibly in the colony Greenland.
Why is radium found in uranium ores but not in barium ores?

What has the author A D McKay written?
A. D. McKay has written: 'Australia's uranium resources, geology and development of deposits' -- subject(s): Geology, Uranium mines and mining, Uranium ores
Is radium common in nature?
Radium is a decay product of uranium and is therefore found in all uranium-bearing ores. (One metric ton of pitchblende yields 0.0001 grams of radium). Radium was originally acquired from pitchblende ore from Joachimsthal, Bohemia, in the Czech Republic. Carnotite sands in Colorado provide some of the element, but richer ores are found in the Democratic Republic of the Congo and the Great Lakes area of Canada, and can also be extracted from uranium processing waste. Large radium-containing uranium deposits are located in Canada (Ontario), the United States (New Mexico, Utah, and Virginia), Australia, and in other places.
Where is unranium found?
Uranium is mined and distilled from underground. 25% of uranium is found in Canada, the rest is in Australia, Kazakhstan, Niger, Russia, and Namibia. Uranium is found in ores, mostly uranium oxides.
What can be found in igneous rocks?
In some special circumstances Igneous rocks host important mineral deposits (ores): for example, tungsten, tin, and uranium are commonly associated with granites and diorites, whereas ores of chromium and platinum are commonly associated with gabbros.
Which elements found in nature have mainly radioactive isotopes?
uranium ores
Why does plutonium not occur in natural ore deposits?
Plutonium occur in deposits of uranium ores but only in ultratraces. In the nature plutonium appear as a result of spontaneous natural fission of uranium isotopes a process with a very low cross section.
Is uranium mainly found in Morocco?
Morocco is not now mentioned as a country with uranium reserves; but phosphates ores contain exploitable uranium (approx. 200 mg/kg). Kazakhstan is the country that produces the most uranium, but large areas of uranium deposits include the area of Central Asia, Southwestern Australia, and the area around the Great Lakes.
