$this->bbcode_second_pass_quote('Tyler_JC', 'H')ow expensive would it be to extract the uranium from the coal?
5.2 tons out of 4 million tons is only 1.3 parts per million of uranium.
A low grade uranium ore has 100 parts per million of uranium.
I haven't seen any studies on this, but it doesn't sound like extracting uranium from coal would be profitable.
Uranium is actually quite abundant. The average rock has around 4 parts per million of uranium so it would be easier to get uranium from the parking lot of a coal plant than the coal itself.
The trick os to get it from the ash left over in all those huge sludge ponds around the world, in those locations the concentration is raised from 1.3 to around 10 ppm, which is still very low. On the other hand the ash is already on the surface, it has been 'mined' and powdered already which should help a little in extraction cost.
