1. Preparation of nuclear grade uranium from uranium minerals (generally a chemical industry process: grinding, dissolution, refining with ion-exchangers, refining by solvent extraction, precipitation, filtration, drying, calcination, reduction, obtaining of the necessary compounds of uranium, etc.).
2. Isotopic enrichment of uranium (in isotope 235U) by a very difficult and expensive separation process (gaseous diffusion, centrifugation, etc.).

Why do you use uranium on the environment?
Uranium is a possible polluting agent of the natural environment, it is not used for the environment. Various forms of uranium are used to fuel nuclear power plants, and a form with very low radioactivity (spent uranium) is used in heavy projectile weapons because it is more dense than lead.
Uranium radiation currie per gram?
a gram of natural uranium having various isotopic makeups has a radioactivity of about .67 microCuries. One Curie is equal to the radioactivity possessed by a gram of radium.
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.
Is a sapphire metallic?
No, sapphire is not a metallic. However, it does contain various metals such as chromium, titanium and iron in small amounts.
What is the main purpose of petroleum refining?
The various hydrocarbons present in petroleum have different boiling points. as the number of carbon atoms in a hydrogen increases,it's boiling point also increases.This property is used to separate the different components of petroleum by fractional distillation.The components with different boiling points are known as fractions, and the process of separating the fractions by fractional distillation is known as refining.
what is the best book on refining precious metals?
One highly recommended book on refining precious metals is "Refining Precious Metal Wastes" by C.M. Hoke. It provides detailed information on various refining techniques, processes, and equipment needed for refining gold, silver, platinum, and other precious metals. It is often considered a comprehensive guide for individuals and businesses involved in precious metal refining.
