Uranium Ore Deposits held in Athens in May, was particularly timely. Forecasts of uranium requirements until the end of the present century, published in mid1973 by NEA/IAEA, show very large and increasing annual demands and the total requirement up to the end of the century has been estimated at as much as three million tonnes uranium.

Copper is the most popular commodity (after uranium) that is mined by ISR (Table 1). There are references to primitive forms of in situ leaching of copper in Roman times, and maybe even long before that in China (O'Gorman et al., 2004). The San Manuel copper mine in Arizona is the best known copper mine exploited by ISR (O'Gorman et al., 2004).

The first essential step in leaching uranium from ore deposits is oxidation of uranium from the +4 state to the +6 state. This reaction has been the subject of many investigations. However, in the insitu leaching process, metal sulfides such as pyrite and molybdenite also compete with the uranium for the oxidant in side reactions.

Uranium ore is a finite resource on the Earth, and carries considerable danger. Although the refined product can create abundant energy, its radioactivity can potentially be a source of contamination and is dangerous to humans. Additionally, the mining process can be severely destructive to local ecosystems; in 2008, the United States government enacted a protective measure for the state of ...

Uranium mining in New Mexico is not what one would consider a success story. In fact, is it fraught with corporate disregard for the land and the indigenous people who worked the mines early on. When AngloAmerican miners appeared on the Colorado Plateau in the late nineteenth century, they extracted uranium, radium, and vanadium from small amounts of pitchblende and carnotite ore.

Uranium mining in New Mexico was a significant industry from the early 1950s until the early 1980s. Although New Mexico has the second largest identified uranium ore reserves of any state in the US (after Wyoming), no uranium ore has been mined in New Mexico since 1998.

· "The bottom line resource is about M lbs of uranium, of which probably about lbs is in the copper pits we are currently mining," he added. "We already have about 1 Mt of that uranium ore stockpiled, and we will continue to stockpile it until we build a uranium plant to extract the metal," said Williams.

· Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM. Uranium, which may be coloed with copper ore, may also be recovered as a side stream, if economical. However, in the United States this is not a general practice.
