Depleted Uranium | IAEA

06.01.2019· Uranium (chemical syol U) is a naturally occurring radioactive element. In its pure form it is a silver-coloured heavy metal, similar to lead, cadmium and tungsten. Like tungsten it is very dense, about 19 grams per cubic centimetre, 70% more dense than lead. It is so dense a small 10-centimetre cube would weigh 20 kilograms.

Simultaneous exposure to mercury and uranium shows significantly more damage to the kidneys than when exposure is to each metal …

It''s Elemental - The Element Uranium

Uranium was discovered by Martin Heinrich Klaproth, a German chemist, in the mineral pitchblende (primarily a mix of uranium oxides) in 1789. Although Klaproth, as well as the rest of the scientific community, believed that the substance he extracted from pitchblende was pure uranium, it was actually uranium dioxide (UO 2).After noticing that ''pure'' uranium reacted oddly with uranium

Geology of Uranium Deposits - World Nuclear …

Brannerite (uranium calcium titanium iron oxide, basically uranium titanate – UTi 2 O 6 – with some calcium and other elements replacing uranium and some iron, and other elements replacing titanium) is particularly important since it occurs as up to 30% of the mineralisation at Olympic Dam and also (<10%) at Valhalla near Mount Isa.


Uranium metal has very high density. When finely divided, it can react with cold water. In air it is coated by uranium oxide, tarnishing rapidly. It is attacked by steam and acids. Uranium can form solids solutions and intermetallic compounds with many of the metals. When exposed to air, uranium metal becomes coated with a layer of oxide.

Direct Method for Producing Scandium Metal …

11.03.2018· The process comprises a simple one-step electrochemical method that reduces the metal oxide to metal powder, and it has been scaled-up for titanium and tantalum . Then, the direct reduction route of the scandium oxide and also the reduction of an aluminium-scandium oxide mix to Al–Sc using this method could be a viable and low cost route to produce the pure Sc metal and Al–Sc alloy.

The uranium is converted to uranium oxide powder, but this does not readily disperse in the air unless the fire creates a lot of turbulence, or is accompanied by explosions.

Early Breakthrough of Molybdenum and …

A permeable reactive barrier (PRB) using zerovalent iron (ZVI) was installed at a site near Cañon City, CO, to treat molybdenum (Mo) and uranium (U) in groundwater. The PRB initially decreased Mo concentrations from about 4.8 to less than 0.1 mg/L; however, Mo concentrations in the ZVI increased to 2.0 mg/L after about 250 days and continued to increase until concentrations in the ZVI were
