Successful Legacy of In situ Recovery of Uranium One of the best kept secrets in Texas is that uranium has been continually mined since the late s Uranium mining was initially conducted by open pit mining followed by conventional milling to produce “yellowcake” which is harnessed to produce electrical energy in nuclear power plantsWith nuclear power generation expected to increase over the coming decades access to this unconventional reserve is a matter of energy security With origins in the mid ’s materials have been developed for the selective recovery of seawater uranium for more than six decades with a renewed interest in particular since
