Highlights Multivariate statistical techniques were used to characterize radioactive data. U-238 in Uro phosphate shows higher degree of mobility (CV% = 82.6). U-238 in Kurun phosphate shows lower degree of mobility (CV% = 64.7). The radioactive variables did not follow a normal distribution. The ratio of Th-230/Th-323 in Uro is nine times than that in Kurun.

Minerals and rocks are the essential building blocks of the geosphere. Although there are over 3,000 species of minerals, only a few of them, such as quartz, feldspar, mica, amphibole, pyroxene, olivine and calcite, occur commonly as rock-forming minerals.

May 11, 2018· Mining of radioactive ore (uranium, phosphate etc.) 4. Nuclear power plants 6. Production of nuclear weapons Radioactive materials used in this production have high health risks and release a small amount of pollution. Thanks to good current health-standards this release is not significant and is not a danger to us unless an accident occurs.

Considerable variations are found in the chemical composition of rock phosphate from different mining areas. In general, sedimentary phosphate rocks, or phosphorites, originated in a marine environment, are characterized by activity concentrations of uranium much higher than .

Uranium is a chemical element with symbol U and atomic number 92. It is a silvery-white metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all its isotopes are unstable (with...

Phosphate mining in the United States - Wikipedia. In 2015, 27.6 million metric tons of marketable phosphate rock, or phosphorite, was mined in the United States, making the US the world's third-largest producer, after China and Morocco.

There was a proposal to mine phosphate from the sea bed on the Chatham Rise, offshore east of the South Island. An average of 240 ppm uranium occurs in the phosphates, which would be dredged then processed onshore at the rate of about 1.5 million tonnes per year for about 35 years 2. In February 2015 the NZ Environment Protection Authority ...
