Abstract
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.
