Abstract:
Method for rhenium recovery from copper solvent extraction solution. It is determined whether the copper solvent extraction solution contains trace amounts of rhenium. If so, a feedstock from the copper solvent extraction solution is provided, which is then filtered, producing filtered feedstock. Trace amounts of rhenium are absorbed from the filtered feedstock using a supply of ion exchange resin selective for rhenium. The ion exchange resin is washed. Trace amounts of rhenium are eluted from the ion exchange resin using a first amount of eluent, a second amount of eluent and a third amount of eluent. The first amount and the third amount of eluent produce supplemental feedstock and the second amount of eluent produces rhenium eluate. The rhenium eluate is collected and the ion exchange resin is protonated.
