What is uranium oxide?
uranium oxide is a radioactive mineral composed of black, gray or brown crystals that are generally opaque and have oily shine. This is also known as uraninite. This ore is the main source of commercial uranium extraction because it has a relatively high concentration of this element. Uraninite is usually mined from sediments of hydrothermal veins and sedimentary rocks, such as sandstone, and can also be obtained as a by -product of gold and silver mining. Je přibližně o 70% hustší než olovo, ale má nižší hustotu ve srovnání se zlatem. Uranus has a wide range of military and civilian applications, especially in nuclear technology because of its ability to produce a permanent nuclear chain reaction.
uranium ore is generally processed at the extraction point for yellow work. Yellowcake is often referred to as uranium oxide, but its complete name is the uranium oxide concentrate and has a U3O8 chemical formula. It is an insoluble yellow powder that contains approximately 80% of this oxide.
The first phase of processing includes grinding of uranium ore and adding water until the consistency of the mud reaches. To oxidate uranium ore, which is dissolved into sulfuric acid. This uranium rich liquid is separated and placed in contact with special resin balls that absorb uranium ions. The acid was used to remove uranium from the beads and form a uranium solution that is very concentrated.
Organic solvent is combined with uranium solution, which is then mixed with ammonium sulfate. This leads to the clotting of a substance known as ammonium, basically a mixture of uranium and ammonia oxides. The ammonium diuranate is then thickened and removed from the solution using rotary filters as a yellow paste. This paste is then roasted to remove all the traces of ammonia, and left behind uranium oxide.
uranium oxide can be further processed into enriched uranium oxide fuel, which is sealed in metal fuel rods that are namontoWays to nuclear reactors to produce heat and steam needed to produce electricity. The by -product of this enrichment process is the exhausted uranium oxide, which is no longer radioactive. Due to the high density of uranium oxide, it can be used in applications where large mass must fit into small spaces such as the counterweight of helicopters and yacht hernia, and is also used in the construction of radiation prosecution, which is much more effective than lead. Exhausted uranium oxides can also be used as dyes in the glass and ceramic industries.
