摘要： Method of ion exchange cobalt recovery. Raffinate including cobalt, zinc, copper, nickel and ferric iron is produced. In the raffinate, the pH is raised, the solids are removed and ferric iron is reduced. A copper recovery ion exchange unit is loaded with ion exchange resin selective for copper. Raffinate is fed into the copper recovery ion exchange unit which is regenerated to recover substantially all copper. A cobalt/nickel/zinc recovery ion exchange unit is loaded with another ion exchange resin selective for cobalt. Raffinate is fed into the cobalt/nickel/zinc recovery ion exchange unit, the ion exchange resin holding cobalt, zinc and nickel, and then displaced. Cobalt/zinc eluent is fed into the cobalt/zinc/nickel recovery ion exchange unit to elute the cobalt and zinc in a cobalt/zinc solution, and then displaced. Nickel eluent is fed into the cobalt/zinc/nickel recovery ion exchange unit to elute the nickel.

摘要： 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.

摘要： A method for extracting cobalt from copper raffinate. First, a supply of raffinate containing at least cobalt, copper, ferric iron and nickel, is provided. The raffinate is pretreated by one or all of raising the raffinate pH level; removing solids; and, reducing ferric iron to ferrous iron. Substantially all copper is removed using first ion exchange resin selective for copper. A second ion exchange resin selective for both cobalt and nickel is used to remove the cobalt and nickel. Cobalt and nickel are separately eluted from the second ion exchange resin.
