Uranium ore is mined in several ways: by open pit, underground or by leaching uranium from low-grade ores (see uranium mining). Uranium ore typically contains 0.1 to 0.25 percent of actual uranium oxides so extensive measures must be employed to extract the metal from its ore.
Professional chemists will be m ore precise and say that fluorine is the most "electronegative" element, meaning that it is the most aggressive electron "thief," because the alkali metals are the most "electropositive" elements, meaning their affinity to "give away" an electron, and electronegativity and electropositivity are not easy to compare, as far as "reactivity" goes.
Chalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes, but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits, there has been a worldwide upsurge of interest in the hydrometallurgical processes of this ore as compared to pyrometallurgy.
