Uranium is a naturally-occurring radioactive element that has been mined and used for its chemical properties for more than a thousand years. It is now primarily used as fuel for nuclear reactors that make electricity. Uranium can be recovered in two ways: by conventional mining of the rock (ore), or by using strong chemicals to dissolve uranium from the rock that is still in the ground and ...

Radiation protection in mining and milling of radioactive ores

Some phosphate rock deposits, such as Mulberry in Florida, are notable for their inclusion of significant quantities of radioactive uranium isotopes. This syndrome is noteworthy because radioactivity can be released into surface waters [12] in the process of application of the resultant phosphate fertilizer (e.g. in many tobacco farming ...

Uranium Mining Overview - World Nuclear Association

This mine is the largest reserve of uranium in the country and its economic viability depends on the associated phosphate exploration. This means that the uranium extraction is subject to the production of phosphoric acid-raw material used in the production of fertilizers (agroindustry).

Wastes From The Extraction And Beneficiation Of Metallic ...

Most of the uranium ore deposits at present supporting these mines have average grades in excess of 0.10% of uranium – that is, greater than 1000 parts per million. In the first phase of uranium mining to the 1960s, this would have been seen as a respectable grade, but today some Canadian mines have huge amounts of ore up to 20% U average grade.

Byproducts - The Phosphate Risk

Today's mining operations range in size from about 5,000 acres to 100,000 acres, with approximately 40% of the product going overseas. But, the waste and mishaps remain the problem of the state and its residents. Some of the by-products that surface are known carcinogens, such as radioactive uranium …

mining of radioactive ore uranium phosphate

The phosphate mining industry is responsible for almost all waste from the nonmetal mining segments, and more than 25 percent of all mining waste discussed. Iron ore and uranium mining also generate large volumes of waste. The waste for each mining segment is broken out by waste type for 1980 and 1982 in Tables 2-10 and 2-11, respectively.
