In Sweden, uranium production took place at Ranstadsverket between 1965 and 1969 by mining of alum shale (a kind of oil shale

) due to the low concentration of uranium in the shale and the availability at that time of comparatively cheap uranium on the world market caused the mine to be closed, although a much cheaper and more efficient leaching process, using sulfur-consuming bacteria, had by then been developed. Since 2005 there have been investigations into opening new uranium mines in Sweden.

. The Canadian government expropriated the Port Radium mine and banned private claimstaking and mining of radioactive minerals.
In 1947, the government lifted the ban on private uranium mining, and the industry boomed through the 1950s, spurred by high prices due to the nuclear weapons programs.
Production peaked in 1959, when 23 mines in five different districts made uranium Canada's number-one export.
That same year, however, the United Kingdom and the United States announced their intention to halt uranium purchases in 1963. By 1963, seven mines were left operating, a number that shrank to only three in 1972.
A price rise caused uranium to boom again in 1975 and 2005.

Most uranium ore in the United States comes from deposits in sandstone

, which tend to be of lower grade than those of Australia and Canada. Because of the lower grade, many uranium deposits in the United States became uneconomic when the price of uranium declined sharply in the 1980s. Today nearly all uranium operations in the United States are In-situ leach.
Regular production of uranium-bearing ore in the United States began in 1898 with the mining of carnotite
Carnotite is a potassium uranium vanadate radioactive mineral with chemical formula K2( U O2)2( VO4)2·3 H2O. The water content can vary and small amounts of calcium, barium, magnesium, iron, and sodium are often present.

in Colorado and Utah, for their vanadium content. The discovery of radium by Marie Curie, also in 1898, soon made the ore also valuable for radium. Uranium was a byproduct. By 1913, the Colorado Plateau uranium-vanadium province was supplying about half of the world's supply of radium.

and vanadium from Peru made the Colorado Plateau ores uneconomic.
Mining revived in the 1930s with higher prices for vanadium. American uranium ores were in very high demand by the Manhattan Project during World War II, although the mining companies did not know that the by-product uranium was suddenly valuable. The late 1940s and early 1950s saw a boom in uranium mining in the western US, spurred by the fortunes made by prospectors such as Charlie Steen.
Uranium mining declined with the last open pit mine (Shirley Basin, Wyoming) shutting down in 1992. United States production occurred in the following states (in descending order): New Mexico, Wyoming, Colorado, Utah, Texas, Arizona, Florida, Washington, and South Dakota. The collapse of uranium prices caused all conventional mining to cease by 1992. In-situ leach mining has continued primarily in Wyoming and adjacent Nebraska as well as has recently restarted in Texas. Rising uranium prices since 2003 have increased interest in uranium mining in the United States.

The impacts of uranium development have raised concerns of scientists and government officials alike. Due to increasing demand, uranium projects have been on the increase, raising concerns about water, public health, and fragile desert ecosystems.
Virginia
In February 2010, the Commonwealth of Virginia contracted the National Research Council and Virginia Polytechnic Institute to oversee a National Research Council study of the potential environmental and economic effects of uranium mining in Virginia. The National Research Council study, funded indirectly by a $1.4 million grant from Virginia Uranium to the Commonwealth, resulted in a report released in December 2011. Uranium mining and processing carries with it a range of potential health risks to the people who work in or live near uranium mining and processing facilities. Some of these health risks apply to any type of hard rock mining or other large-scale industrial activity, but others are linked to exposure to radioactive materials. In addition, uranium mining has the potential to impact water, soil, and air quality, with the degree of impact depending on site-specific conditions, how early a contaminant release is detected by monitoring systems, and the effectiveness of mitigation steps.
Some of the worker and public health risks could be mitigated or better controlled through modern internationally accepted best practices, the report says. In addition, if uranium mining, processing, and reclamation were designed, constructed, operated, and monitored according to best practices, near- to moderate-term environmental effects should be substantially reduced, the report found.
However, the report noted that Virginia's high water table and heavy rainfall differed from other parts of the United States—typically dry, Western states—where uranium mining has taken place. Consequently, federal agencies have little experience developing and applying laws and regulations in locations with abundant rainfall and groundwater, such as Virginia. Because of Virginia's moratorium on uranium mining, it has not been necessary for the Commonwealth's agencies to develop a regulatory program that is applicable to uranium mining, processing, and reclamation.
The report also noted the long-term environmental risks of uranium tailings, the solid waste left after processing. Tailings disposal sites represent potential sources of contamination for thousands of years. While it is likely that tailings impoundment sites would be safe for at least 200 years if designed and built according to modern best practices, the long-term risks of radioactive contaminant release are unknown.
The report's authoring committee was not asked to recommend whether uranium mining should be permitted, or to consider the potential benefits to the state were uranium mining to be pursued. It also was not asked to compare the relative risks of uranium mining to the mining of other fuels such as coal.
