Lorandite from Allchar as geochemical detector for pp ...

Jul 01, 2018  LOREX (LORandite EXperiment) is a geochemical project addressing the solar proton–proton neutrino flux for the period of 4.31(2) Ma from the reaction 205 Tl + ν e → 205 Pb + e − with a very low threshold (52 keV) for solar pp-neutrino capture. A decisive step for this purpose is to obtain the precise, background-corrected ratio of 205 Pb/ 205 Tl in the mineral lorandite

Thallium - Occurrence and Production Occurrence ...

Thallium is found in the minerals crookesite TlCu 7 Se 4, hutchinsonite TlPbAs 5 S 9, and lorandite TlAsS 2. Thallium also occurs as a trace element in iron pyrite, and thallium is extracted as a by-product of roasting this mineral for the production of sulfuric acid. Thallium can also be obtained from the smelting of lead and zinc ores.

Environmental Risks of Mining

Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.
