Mineralogy and Occurrence of Uranium & Thorium Ore Minerals

Mineralogy and Occurrence of Uranium & Thorium Ore Minerals . The chemistry of uranium is such that it can form both a cation and oxyanion in natural waters (ions that are positively- and acutely-negatively charged) and can combine with different chemical groups

It's Elemental The Element Uranium

To produce uranium-233, atoms of thorium -232 are exposed to neutrons. Thorium-233 forms when thorium-232 absorbs a neutron. Thorium-233 has a half-life of about 22 minutes and decays into protactinium -233 through beta decay. Protactinium-233 has a half-life of about 27 days and decays into uranium-233, also through beta decay.

majority of samples, concentrations of uranium fall in the range from slightly below 1 to 4 parts per million (ppm). Similar uranium concentrations are found in a vari-ety of common rocks and soils, as indicated in figure 2. Coals with more than 20 ppm uranium are rare in the United States. Thorium concentrations in coal fall within a similar

Uranium ore

Unconformity-type uranium deposits host high grades relative to other uranium deposits and include some of the largest and richest deposits known. They occur in close proximity to unconformities between relatively quartz-rich sandstones comprising the basal portion of relatively undeformed sedimentary basins and deformed metamorphic basement rocks. These sedimentary basins are typically of Proterozoic age, however some Phanerozoic examples exist.

From its natural state, 232 Th decays through a number of stages to eventually form 208 Pb, which is stable.The main difference is that thorium is far less mobile than uranium in oxidising surface conditions (Mernagh and Miezitis, 2008).

Thorium World Nuclear Association

Thorium exists in nature in a single isotopic form Th-232 which decays very slowly (its half-life is about three times the age of the Earth). The decay chains of natural thorium and uranium give rise to minute traces of Th-228, Th-230 and Th-234, but the presence of these in mass terms is negligible. It decays eventually to lead-208.

May 11, 2014 Attempts to recover uranium 233 from its irradiated thorium fuel were described, however, as a “financial disaster.” The last serious attempt to use thorium in a commercial reactor was at the Fort St. Vrain plant in Colorado, which closed in 1989 after 10 years and hundreds of equipment failures, leaks, and fuel failures.

The next main element in the decay chain is the short lived radioactive gas, Radon. Despite a half life of just 3.2 days, the gas is abundant as it forms through decaying Uranium and Thorium which is found often in granite bedrock (pictured). As such, granite buildings such as New York's Grand Central Station emit significant amounts of radiation.

Why Is Thorium, A Potentially Safer Alternative To Uranium

Oct 21, 2020 Since the fission of thorium doesn’t produce plutonium (one of the elements used in nuclear weapons) as a byproduct, uranium, the dual-purpose nuclear fuel, took precedence. However, nations have finally begun to understand the safety aspects of thorium as a nuclear fuel and have started developing thorium-based nuclear reactors.

Aug 17, 2020 Fortuitously, HMBA was again ideal for this purpose, because while it forms complexes more readily with uranium, it will still form complexes with thorium at high concentrations. Thus, although thorium is negatively charged in a low concentration HMBA solution, it will form a positively charged complex in a high concentration HMBA solution.
