Separation of uranium isotopes is really hard compared with refining ores (the difference in U-235 vs 238 and others is a small mass fraction). Other useful info might also be found for AMS (atomic mass spectroscopy), used for, e.g. C-14 dating. Again, they want a very precise, single pass measurement. Cascades of Calutrons might be more efficient.
To highlight the improvement Foley's solution presents, consider that it costs $1,520 to extract one kilogram of gold using aqua regia and results in 5,000 litres of waste. With the U of S ...

The main mechanisms behind venous ulcers are reflux, venous outflow obstruction, or the combination of the two. 5 Reflux is the most common reason, whereas obstruction is rare. Reflux and obstruction have the highest odds for skin damage. 6 Malfunction in the foot and calf muscle pumps by itself could cause ulceration, but it is most prevalent in patients with venous disease. 5 All the causes ...
