  • METHOD FOR RECOVERING A METAL FROM SOLUTION, SYSTEM FOR RECOVERING A METAL FROM SOLUTION, AND SYSTEM FOR RECOVERING LITHIUM FROM SALT WATER
    Publication number: 20150129433
    Abstract: In a method for recovering a metal from a solution, a first electrode that includes a metal for recovery and a second electrode that includes a metal different from the metal for recovery are prepared. The first electrode and the second electrode are immersed in a first solution that includes a metal ion for recovery. The metal ion for recovery in the first solution is combined with the first electrode. The first electrode and the second electrode are charged while immersing the first and second electrodes in a second solution different from the first solution so that the metal ion for recovery is separated from the first electrode. The metal for recovery is recovered from the second solution.
