A review of acid leaching of uraninite ScienceDirect

Uranium is widely distributed in the Earth''s crust with estimates of its abundance varying between 2 and 4 ppm (Clark et al., 2006, Fleischer, 1955).Uranium in the crust is concentrated in over 200 mineral species that contain uranium as a necessary structural constituent in either the reduced U 4 + or oxidised U 6 + valence state. The main economic uranium minerals are the tetravalent species

Lead (/ ˈ l ɛ d /) is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is silvery with a hint of blue it tarnishes to a dull gray color when exposed
