A Wikipedia article (see link below) gives the concentration of uranium in ore as 0.01 to 0.25 percent, which is a wide range. If we take 0.1 percent as typical, then 1 tonne (1000Kg) of ore would produce 1 Kg of uranium. This is natural uranium, which is normally enriched by about six times to produce suitable enriched uranium for fuel, so you can say that about 6 tonnes of ore would be needed to give 1 Kg of enriched uranium, but there is considerable variation of this from one source of ore to another

Why is uranium enriched in fuel pellets?
Uranium is actually enriched as a gas, uranium hexafluoride. This is then chemically treated to turn it into a solid material, in most reactors it is uranium dioxide that is used as fuel. In PWR and BWR designs (and AGR in the UK) it is made into small cylinders 10mm diameter which are then stacked end to end inside a sheath, to make a fuel rod. So to describe this as "pelletts" is not quite accurate.
In the metric system how many grams are needed to make one kilogram?

Does the government use uranium?
Yes, the government uses uranium. Uranium is mined, refined and then enriched to provide nuclear fuel for nuclear reactors. Depleted uranium, the uranium "left over" from enrichment, is used in munitions to defeat armor, and in some types of armor. On a related note, enriched uranium is in demand by some sovern states and religeous/political factions to make nuclear weapons, though the "modern" nuclear powers use plutonium as the fissionable element in their nuclear devices. The plutonium is made by "soaking" uranium in the neutron flux of an operating nuclear reactor for a time. This changes (transmutes) some of the uranium to plutonium, which is then recovered and processed.
What elements or compounds will make uranium explode?
The burning and exploding of uranium are entirely different processes.uranium burns by ordinary chemical oxidation, in fact uranium reacts with oxygen so easily that it is called a pyrophoric material: shavings or dust will suddenly spontaneously combust with no warning whatsoeveruranium in a nuclear bomb explodes by an exponentially increasing fission chain reaction in a supercritical mass
What is an uranium dioxide?
Any rock or mineral containing economically recoverable quantities of Uranium compounds is a Uranium ore. These compounds are most commonly various oxides, silicates, titanates, phosphates, vanadates, arsenates, etc. of Uranium.To get pure Uranium metal from the ore various processes can be used, but a basic outline of the steps goes something like:Crush the ore to particles roughly the size of dust.Mix with chemicals to dissolve the crushed ore and change the oxidation state of the Uranium separating it chemically from the ore molecules.Mix with chemicals that cause the separated Uranium atoms to react with them, forming a precipitate (a Uranium oxide called yellowcake).Filter the solution, the Uranium precipitate will stay in the filter while the rest passes through as waste. Wash in the filter to make sure none of the waste remains to contaminate the Uranium precipitate.Dry the yellowcake powder.Mix yellowcake with magnesium metal granules and heat red hot in a crucible. The mixture will ignite leaving Uranium metal in the bottom of the crucible and magnesium oxide slag on top.Uranium is usually enriched first for reactors and bombs instead of just being converted to metal, also most power reactors use enriched yellowcake not the pure metal. To enrich Uranium the basic outline goes something like this:Mix yellowcake with nitric acid, then ammonia, then hydrogen gas, then hydrofluoric acid, then fluorine gas to produce Uranium hexafluoride.The Uranium hexafluoride it heated to become a gas in an enrichment plant (e.g. gaseous diffusion, gas centrifuge). The products are enriched Uranium hexafluoride (e.g. more Uranium-235) and depleted Uranium hexafluoride (e.g. less Uranium-235) from opposite ends of the plant.The Uranium hexafluoride (of either or both types is converted back to yellowcake.
What is the feul for nuclear power plants and where does it come from?
Either yellow uranium oxide (yellowcake) or metallic uranium in most reactors. In moderated thermal neutron reactors the uranium is usually enriched to 3% to 5% uranium-235 isotope, in unmoderated fast neutron reactors the uranium is enriched to 20% to 95% uranium-235 isotope. This uranium comes from mines (similar to coal or iron ore mines). What is mined is usually black uranium oxide ore. This ore is processed to make unenriched yellowcake (0.7% uranium-235) and shipped to the enrichment plant. Most enrichment plants process the yellowcake to make uranium hexafloride then run that through their system, producing both enriched uranium (product) and depleted uranium (waste). The enriched uranium hexafloride is then processed back to yellowcake and shipped to a finishing plant that uses it to make the required fuel assemblies.
What is the procedure to make atomic bomb?
Uranium or plutonium is enriched to create to create a core capable of nuclear fusion and fission.
What element is needed to make a nuclear weapon?
A nuclear weapon requires enriched uranium or plutonium as the fissile material to sustain a chain reaction and create a nuclear explosion. Additionally, a conventional chemical explosive is needed to trigger the nuclear reaction.

What were the two atomic bombs that were dropped on japan made of?
The MK-I Little Boy had about 100 pounds of 80% enriched uranium and about 4 tons of other stuff needed to make that explode.The MK-III Fat Man had about 15 pounds of plutonium and about 5 tons of other stuff needed to make that explode.
Enriched fuel pellets are used to make what?
Enriched fuel pellets are used to fuel nuclear reactors, particularly in nuclear power plants. These pellets consist of enriched uranium to sustain the nuclear fission process that generates heat to produce electricity.
How do you make uranium products?
Uranium itself is a naturally occurring metal, but seldom found as the native metal. The usual method of refining it from its oxides, (after reduction) is to convert into a chemical gas (uranium hexafluoride), and centrifuge this to obtain the particular isotope needed. Not a short process. UF6 is highly toxic and reactive. Naturally, any uranium compound is radioactive, and dangerous to handle without particular precautions.
Are the atomic bomb and depleted uranium the same weapon?
No, the atomic bomb and depleted uranium are not the same thing. Nuclear weapons are made with enriched uranium or with plutonium as the fissionable material. Depleted uranium is uranium that is "left over" after natural uranium is put through a process called enrichment to inprove the concentration of the isotope U-235 over that in natural uranium. The enriched uranium with its higher percentage of U-235 is fissionable, and it can be used in nuclear reactors and in nuclear weapons. Depleted uranium is used to make armor-piercing projectiles, and can be put through the neutron flux in an operating reactor to be transformed (transmuted) into plutonium.

How much uranium is needed to make a nuclear weapon?
It typically takes about 15-25 kilograms of highly enriched uranium (HEU) or 3-5 kilograms of plutonium to make a nuclear weapon. The exact amount can vary depending on the design and efficiency of the weapon. The International Atomic Energy Agency closely monitors and regulates the use and handling of these nuclear materials to prevent proliferation.

What is a uranium pellet?
You are orobably thinking of the small cylinders which make up the fuel rods. These are 10mm diameter and about 10mm long, and are packed end to end inside the zircaloy sheath to make a fuel rod. The material is uranium dioxide with the uranium enriched to about 5% U-235.
