    uraninite: a radioactive mineral and ore of uranium

    It received its name from its uranium content. Uraninite is highly radioactive and should be handled and stored with care. It is not a suitable mineral for classroom use. Uraninite has an ideal chemical composition of UO 2, but the mineralogical and chemical composition of specimens varies in response to their levels of oxidation and radioactive decay. "Pitchblende" is an archaic name that was used for uraninite …

    Chemical mining Stations can be boosted 3 hours for 10 gems. Note that the level 2 upgrade costs resources that sell for 24,000 coins, or 12,000 per resource per ten minutes; this means that it is not worth upgrading a chemical mine until the cost for a new mine exceeds 60,000, which occurs after 4 chemical mines (the fifth one will cost

    improving subsurfaceuranium cleanupmethods

    A team of scientists has documented multiple chemical reactions that transform hexavalent uranium [U (VI)] to more insoluble forms of tetravalent uranium [U (IV)] in subsurface sediments at a uranium contamination site. This information could lead to improved cleanup methods by enabling remediation designers to enhance the transformation of soluble U (VI) to more insoluble forms of U (IV), such as …
