“…Tl in these deposits was likely mobilized and transported with hydrocarbons and brines though could be related to the inferred intrusion that might also account for the Au and Ag present in the U-V deposits. Tl disperses readily and accumulates in soil, water transport and food crops such as cabbage, affecting the health of people [110]. Tl forms highly volatile complexes with halides and can enter the crystal lattices of sulfides and sulfosalts [111].…”

Abstract:The origin of V, U, REE and other metals in the Permian Phosphoria Formation have been speculated and studied by numerous scientists. The exceptionally high concentrations of metals have been interpreted to reflect fundamental transitions from anoxic to oxic marine conditions. Much of the oil in the Bighorn Basin, is sourced by the Phosphoria Formation. Two of the top 10 producing oil fields in Wyoming are located approximately 50 km west of two abandoned U-V mining districts in the northern portion of the basin. These fields produce from basin margin anticlinal structures from Mississippian age reservoir rock. Samples collected from abandoned U-V mines and prospects hosted in Mississippian aged paleokarst in Montana and Wyoming have hydrocarbon residue present and contain anomalous high concentrations of many metals that are found in similar concentrations in the Phosphoria Formation. As, Hg, Mo, Pb, Tl, U, V and Zn, often metals of environmental concern occur in high concentrations in Phosphoria Formation samples and had values ranging from 30-1295 ppm As, 0.179-12.8 ppm Hg, 2-791 ppm Mo, <2-146 ppm Pb, 10-490 ppm Tl, 907-86,800 ppm U, 1240-18,900 ppm V, and 7-2230 ppm Zn, in mineralized samples from this study. The REE plus Y composition of Madison Limestone-and limestone breccia hosted-bitumen reflect similar patterns to both mineralized samples from this study and to U.S. Geological Survey rock samples from studies of the Phosphoria Formation. Geochemical, mineralogical and field data were used to investigate past theories for mineralization of these deposits to determine if U present in home wells and Hg content of fish from rivers on the proximal Crow Indian Reservation may have been derived from these deposits or related to their mode of mineralization.

Thallium (Tl) is a highly volatile and toxic heavy metal regarded to cause pollution even at very low concentrations of several parts per million. Despite the extremely high risk of Tl in the environment, limited information on removal/recovery exists. The study focussed on the use of green algae to determine the sorption potential and recovery of Tl. From the study, removal efficiency was achieved at 100% for lower concentrations of ≥ 150 mg/L of Tl. At higher concentrations in a range of 250-500 mg/L, the performance of algae was still higher with sorption capacity ( max q ) between 830 and 1000 mg/g. Generally, Chlorella vulgaris was the best adsorbent with a high max q and lower affinity of 1000 mg/g and 1.11 L/g respectively. When compared to other studies on Tl adsorption, the tested algae showed a better max q than most adsorbents. The kinetic studies showed better correlation co-efficient of ≤ 0.99 for Pseudo-second order model than the first order model. Recovery was achieved highest for Chlorella vulgaris using nitric acid at 93.3%. The strongest functional groups responsible for Tl binding on the algal cell wall were carboxyl and phenols. Green algae from freshwater bodies showed significant potential for Tl removal/recovery from industrial wastewater.
