Leaching mechanism of pitchblende by Acidithiobacillus ferrooxidans
Then she found that pitchblende was more radioactive than uranium by itself.
From all that wagonload of pitchblende, there was left only a tiny pinch of stuff in a jar.
By good fortune they were able to get from the movement of Austria a ton of pitchblende.
Particularly part of pitchblende samples with colloidal structure features have the same physical and optical features as uraninite.
The principal uranium mineral in the deposits of primary subtype is uraninite, but in reworked subtype are pitchblende and relict uraninite.
We found that pitchblende contains at least two radioactive materials, one of which, accompanying bismuth, has been given the name polonium, while the other, paired with barium, has been called radium.
