When uranium ore is extracted from the ground, 99.28% of the mined ore is treated as waste as the uranium isotopes used in nuclear power plants mainly is uranium-235 leaving behind the major portion of the ore which constitutes of uranium-236 and uranium-238 as well as some other components. This waste (also referred to as tailings) is then neutralised with lime and carried through pipelines to a tailing pond. This transport is made possible through
