Environmental Impacts of Uranium Mining - Stanford University
Uranium ore is generally processed through grinding the ore materials to a uniform particle size, which is then treating through chemical leaching to extract the uranium. This results in a dry powder form of the natural uranium commonly referred to as "yellow cake." [2]
