Provided are processes for extracting nickel and lithium from a Nickel(II)/Lithium(I) (Ni 2+ /Li + ) solution. The process for extracting nickel and lithium includes providing a Ni 2+ /Li + solution comprising an amount of lithium and an amount of nickel, treating the Ni 2+ /Li + solution with an alkaline agent to adjust the pH of the Ni 2+ /Li + solution to between about 1.0 to about 10.0, and treating the Ni 2+ /Li + solution with a nickel selective extractant, the nickel selective extractant suitable to extract nickel from the Ni 2+ /Li + solution at said pH to thereby produce a Li + solution with less than 10 parts per million Ni 2+ . Once complete, the process provides for recoverable nickel and/or lithium that may be recycled into batteries or sold for other uses. |
