Uranium Ore (Carnotite). Milling: This process takes place at a mill after the ore containing uranium is removed from the Earth through open pit or underground mining.The ore is brought to a mill, crushed, and ground up before chemicals are added to dissolve the uranium. The uranium is then separated from the chemical solution, solidified, dried and packaged.

used to chem mill titanium alloys. Because of the local concentration of hydrogen gas during chem mill process is high; hydrogen content in the post chem mill parts can cause the embrittlement of the parts. In order to remediate the effect of hydrogen, it is necessary to reduce/remove hydrogen in situ and nitric acid is used to serve that purpose.

Bromine concentration in samples analyzed by Dong (2005) is of a trace level (e.g., 57 ppm). A single study (Broska et al., 2014) reports a possible trace-amount occurrence of CN-(cyanide) admixture in fluorapatite. Vanadium-rich members of the ellestadite group are observed in pyrometamorphic rocks formed in a burning coal-mining dump (Kruszewski, pers. obs.).
