Provided are processes for extracting nickel and lithium from a Ni/Lisolution. The process for extracting nickel and lithium includes providing a Ni/Lisolution comprising an amount of lithium and an amount of nickel, treating the Ni/Lisolution with an alkaline agent to adjust the pH of the Ni/Lisolution to between about 1.0 to about 10.0, and treating the Ni/Lisolution with a nickel selective extractant, the nickel selective extractant suitable to extract nickel from the Ni/Lisolution at said pH to thereby produce a Lisolution with less than 1000 parts per million Ni. Once complete, the process provides for recoverable nickel and/or lithium that may be recycled into batteries or sold for other uses.

Methods for extracting elements from a solution

Provided are processes for extracting lithium and optionally nickel from a Nickel(II)/Lithium(I) (Ni/Li) solution. The extraction is optionally performed in a series of steps with counterflow of aqueous and organic flows to thereby produce a lithium poor solution. The lithium poor solution may be treated so that remaining Ni in the lithium poor solution may be directly precipitated therefrom in the form of a Ni salt. Once complete, the process provides for recoverable nickel and/or lithium that may be recycled into batteries or sold for other uses.
