  • Mining risks: Coal, uranium, phosphate, bauxite, iron ore

    Uranium mining risks Risks common to uranium mining are centred on radiation Countries such as Australia and Canada have really clamped down on uranium mining and how they deal with the radioactive impact of the material Everyone is exposed to radiation, so the new rules and regulations around uranium mining1 Introduction Phosphate rocks of sedimentary origin contain Uranium (238 U), Thorium (232 Th) and its decay products in addition to phosphate minerals (Roesseler, 1990)Considerable variations are found in the chemical composition of rock phosphate from different mining areasNatural radioactivity assessment of a phosphate fertilizerThe production of fertilizers from natural phosphate ore can lead to the redistribution of uranium and other radionuclides in products, byproducts and residues and, hence, to environmental impacts and increased radiation exposures Uranium and other radionuclides are mainly found in the process residue phosphogypsum and to a lesser degree inUranium in phosphate fertilizer production | SpringerLink
