Today nothing, only a yellow sign remains on the spot where an silent, innocuous yellow substance once provided a livelihood to thousands of people, but also killed hundreds of thousands more. Upon passage of UMTRCA, little thought was given to the groundwater contamination. The mines are located about 10 miles southeast of the Cameron, AZ, and are away from population centers. Most of those locations are found in Colorado, Utah, New Mexico, Arizona, and Wyoming. The principle health threat associated with uranium mines, ore, and tailings is the accompanying colorless, odorless radon gas, which is radioactive and heavier than air, so it settles and accumulates in low places, such as crawl spaces and basements.Through a number of chemical processes vanadium, and then uranium, were precipitated from solution at the Old Rifle mill.

Much of the uranium present in economic concentrations occurs in the desert southwest, so most of the products’ mines and mills were located on the Colorado Plateau, which extends from the U.S. Four Corners states north into Wyoming. In this period, the United States government began work on an ultra-secret project that years later would become known as the Manhattan Project. A patchwork of state and federal regulations makes it next to impossible to regulate their cleanup. [45] In response to the proposed mining in Weld county, state lawmakers have put forward two proposals to more closely regulate uranium mining in Colorado; the first would require that mining companies prove that groundwater would not be adversely affected before mining could begin; the second would assure that local governments have the power to set health and environmental standards.

Found insideNow expanded to include the story of nuclear testing and its consequences, Uranium Frenzy has become the classic account of the uranium rush that gripped the Colorado Plateau region in the 1950s. The uranium would be stripped from the leachate using ion exchange resin. The Colorado Plateau's communities and landscapes continue to be poisoned by our region's uranium legacy, which includes thousands of abandoned mines and numerous mill sites, along with polluted soil, air, and water. Uranium is present as uraninite, coffinite, and meta-autunite in Eocene and Oligocene arkosic sandstone, conglomerate, and in sediments interbedded with Miocene volcanic flows. In 1919, prospectors discovered that the sandstone contained uranium and vanadium, and about 40 tons of ore containing up to 1% uranium was mined from underground workings. Mining began at Graysill Mines, Colorado in 1945 with miners looking for uranium. The mill was left abandoned along with several million tons of unprocessed ore. Ores were treated in a local ore mill, five miles (8.0 km) east-northeast of Maybell, during the 1953–1964 period; during 1976–1981, ore was heap-leached, and the eluate trucked to Wyoming for uranium recovery. Uravan (a contraction of uranium/vanadium) is an abandoned uranium mining town in western Montrose County, Colorado, United States, that is now a Superfund site. [6] The deposit consists of Tertiary hydrothermal veins filling fracture zones oriented predominantly NNW-SSE in gneiss, schist, and quartzite of the Precambrian Idaho Springs Formation. [13] But it was not until 1911 that the radium content of carnotite was confirmed by the Marie Curie laboratory in Paris. Union Carbide Corporation began milling the ore in 1924 at what is now referred to as the Old Rifle mill site.The plant was shut down in 1932 due to a poor market, but reopened in 1942 to produce vanadium for the war effort. A. 169 AUMs are located 40 miles southwest of Mount Rushmore in the Black Hills. 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. Ore was taken from numerous open-pit mines between two and three miles north of US Highway 40, between the towns of Maybell and Lay from 1953–1964 and 1976–1981.
