Technical grade V 2 O 5 is produced as a black powder used for the production of vanadium metal and ferrovanadium. A vanadium ore or vanadium-rich residue is treated with sodium carbonate and an ammonium salt to produce sodium metavanadate, NaVO 3.This material is then acidified to pH 2–3 using H 2 SO 4 to yield a precipitate of "red cake" (see above).The red cake is then melted at 690 °C ...

Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written 235 U) has been increased through the process of isotope separation.Naturally occurring uranium is composed of three major isotopes: uranium-238 (238 U with 99.2739–99.2752% natural abundance), uranium-235 (235 U, 0.7198–0.7202%), and uranium-234 (234 U, 0.0050–0.0059%).

The effective dose from inhalation of 1 mg uranium ore of an ore grade of 0.1% U is 0.42 µSv (for higher ore grades, the dose increases correspondingly). The 20 mSv annual standard is equivalent to 47.6 g. This corresponds to a uranium ore concentration in air of 16.5 mg/m 3. (See also: Uranium Radiation Individual Dose Calculator)

The earth's crust contains an average of about 3 ppm (= 3 g/t) uranium, and seawater approximately 3 ppb (= 3 mg/t). Naturally occuring uranium consists of three isotopes, all of which are radioactive: U-238, U-235, and U-234. U-238 and U-235 are the parent nuclides of two independent decay series, while U-234 is a decay product of the U-238 series. Properties of the Natural Uranium Isotopes ...
