  • Enriched uranium

    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, …

  • U.S. appeals court says CFPB funding is unconstitutional

    A three-judge panel of the New Orleans-based 5th Circuit Court of Appeals found Wednesday that the CFPB's funding structure violated the Constitution's separation of powers doctrine. As set up under the 2010 Dodd-Frank Act, the CFPB is funded by the Federal Reserve rather than congressional appropriations.

  • Tin

    Tin is a chemical element with the symbol Sn (from Latin: stannum) and atomic number 50. Tin is a silvery-coloured metal. Tin is soft enough to be cut with little force and a bar of tin can be bent by hand with little effort. When bent, the so-called "tin cry" can be heard as a result of twinning in tin crystals; this trait is shared by indium, cadmium, zinc, and mercury in the solid state.

  • Mining industry and sustainable development: time for change

    The common mining practice until very recently could be summarized in a few steps: from obtaining a license, dig the ore, sell the metal, and, once the deposit was exhausted, walk-away and start another mine elsewhere (Jain et al. 2016; EB 2017). Not surprisingly, mining is among the human activities with widest environmental and social impacts.

  • Atom

    The heaviest stable atom is lead-208, with a mass of 207.976 6521 Da. As even the most massive atoms are far too light to work with directly, chemists instead use the unit of moles. One mole of atoms of any element always has the same number of atoms (about 6.022 × 10 23). This number was chosen so that if an element has an atomic mass of 1 u ...

  • Radium

    Radium was discovered in 1898 by Marie Curie and Pierre Curie. They managed to extract 1 mg of radium from ten tonnes of the uranium ore pitchblende (uranium oxide, U 3 O 8), a considerable feat, given the chemically methods of separation available to them.They identified that it was a new element because its atomic spectrum revealed new lines.

  • Magnetite

    Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 2+ Fe 3+ 2 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. With the exception of extremely rare native iron deposits, it is the most magnetic of all the naturally occurring minerals on Earth.

  • Lead Price

    Most lead ores contain a small percentage of lead, usually about 3-8%, that must be concentrated for extraction. During the initial process, ores undergo a process of grinding, crushing, froth floatation, dense-medium separation, and drying. This process results in a concentrate that is composed of 30-80% lead by mass.
