Uranium Mine Leaching

Aug 27 2020018332Uranium leaching Although less uranium than copper is obtained by microbial leaching the uranium process is more significant economically Because a thousand tons of uranium ore must be handled to obtain one ton of uranium in situ microbial leaching is gaining greater acceptance since it eliminates the expense of moving such vast amounts of.
