Abstract
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.
