  • Uranium mining in Colorado Wikipedia

    Uranium mining in Colorado, United States, goes back to 1872, when pitchblende ore was taken from gold mines near Central City, Colorado.The Colorado uranium industry has seen booms and busts, but continues to this day. Not counting byproduct uranium from phosphate, Colorado is considered to have the third largest uranium reserves of any US state, behind Wyoming and New Mexico.

  • Granite Wikipedia
    OverviewMineralogyOccurrenceOriginAscent and emplacementWeatheringGranite is nearly always massive, hard, and tough. These properties have made granite a widespread construction stone throughout human history. The average density of granite is between 2.65 and 2.75 g/cm3, its compressive strength usually lies above 200 MPa, and its viscosity near STP is 3–6·1019 Pa·s. The melting temperature of dry granite at ambient pressure is 1215–1260 °C; it is strongly reduced in the presence of water, down to 650 °C at a few kBar pressure. Granite has poor...

Where orebodies are deeper, underground mining is usually employed, involving construction of access shafts and tunnels but with less waste rock removed and less environmental impact. In either case, grade control is usually achieved by measuring radioactivity as a surrogate for uranium concentration.*...

    Uranium never occurs as bare metal; rather, it most often occurs in oxides as the minerals uraninite (UO 2) or pitchblende (partially oxidized uraninite, conventionally given as U 3 O 8).In solution, uranium travels in molecular complexes with carbonate, sulfate and chloride as long as the chemical conditions are oxidizing. But under reducing conditions, uranium drops out of solution as oxide
