The Quivira Mining Corporation—occasionally referred to as Quivera—was a uranium extraction enterprise under the ownership of Kerr-McGee. Founded in 1983, Quivira managed the uranium processing facility originally constructed by Kerr-McGee in 1958, located at Ambrosia Lake, New Mexico. This mill was engaged in the treatment of uranium ore and the recovery of mine water from 1966 until it ceased operations in 2002. Throughout the period from the 1970s into the early 2000s, containment structures such as tailings disposal cells and evaporation ponds were developed to handle byproducts, process water, uranium tailings, and radioactive waste, all while adhering to environmental standards and regulatory requirements.

In 1989, ownership of Quivira transferred to Rio Algom Mining, which itself was acquired by Billiton in 2000. After Billiton merged with BHP in 2001 to create BHP Billiton, Rio Algom was divested to Uranium Resources in 2007. Nevertheless, Uranium Resources withdrew from its proposed acquisition of Rio Algom from BHP Billiton in June 2008.
