Herein, a novel online extraction device that incorporates a heating unit was fabricated to efficiently extract the uranium from ore, followed by real-time ICP-MS detection. As a result, without sample pretreatment, the uranium content in two kinds of uranium ore can be obtained directly within 15 min with low sample consumption (1.0 …

Uranium is a chemically very reactive, highly toxic, grey heavy metal. Like all actinides, uranium metal is radioactive, after thorium metal, it is the second most stable of those. The most abundant natural isotope of uranium metal is 238U with a half-life of 4.5 billion years. The basis for nuclear power plants is the fissile isotope 235U.

In the untreated ore sample T-O-F, uranium is mainly bound in uraninite which is principally enclosed in carbonaceous nodules. Small amounts of uranium were also found in monazite and xenotime (YPO 4), whereas thorium is mostly bound in uraninite. Nitric acid was found to be the most efficient digestion agent for extraction of …

The major primary ore mineral is uraninite (basically UO 2) or pitchblende (U 2 O 5.UO 3, better known as U 3 O 8), though a range of other uranium minerals are found in particular deposits. These include carnotite (uranium potassium vanadate), the davidite-brannerite-absite type uranium titanates, and the euxenite-fergusonite-samarskite group ...

These samples of uranium ore were sold at the American Museum of Atomic Energy in Oak Ridge, Tennessee, sometime during the 1950s or 1960s. Each plastic case is 1 1/8" x 1 1/8" x 5/8" in size. During tours of the Museum, visitors would stop at the gift shop (don't all tours end at a gift shop?) where the ore samples and other items would be sold.

These two isotopes might produce an intense gamma signal even when uranium is not present, or with a much smaller activity, in the ore. Therefore, gamma spectroscopy measurements of core samples are performed on the surface with HPGe detectors to directly characterize uranium activity from the 1001-keV gamma ray of 234 mPa that is …
