Abstract
A method for recovering NiSO.6HO crystals from a nickel rich organic phase is provided. The method includes contacting a nickel rich organic phase with an aqueous strip solution of sufficient HSOconcentration to extract nickel from the organic phase and of sufficient Niconcentration to precipitate NiSO.6HO crystals and form a nickel lean organic phase. Also provided are methods for recovering NiSO.6HO crystals that include preceding processing steps, including low temperature pressure oxidation (LTPOX) autoclaving of a nickel sulphide concentrate to afford a pregnant leach solution (PLS).
