Bis picolylamine Resins for Nickel Recovery from Laterite nickel Resource

 Bis-picolylamine Resins for Nickel Recovery from Laterite-nickel Resource

Nickel, a silver-white, hard, ductile and ferromagnetic metal element that is highly polished and resistant to corrosion. Nickel is a pro-iron element, so nickel-based minerals are mostly laterite nickel ore.

Driving by the strong EV demand, Nickel demand is increasing year by year, the traditional method of Ni recovery is by solvent extraction. Pretreatment by precipitating Fe3+ is needed before extraction. During the precipitation, max 10% Nickel would enter into the residues and are very hard to recover(high loss of nickel). On the other hand Saponification of the extractant will consume NaOH.

Seplite LSC 495 of Bis-picolylamine groups which is specially designed for direct extracting nickel from acid leaching liquors of laterite.

Our Technology Advantages:

Suitable being used in strong acid liquors(0-2), no need to adjust PH

Suitable being used in high Fe content liquors(like 20,000ppm etc), no need to precipitating Fe3+

HIgh nickel loading capacity under PH 0-1

Much less nickel loss considering the whole process

Much smaller system leading to much less effluents, regeneration costs and equipment CAPEX.

Special Chelating Resins for Nickel Extraction:

SEPLITE® LSC495 Bis-picolylamine Resin has high selectivity to Ni and is not affected by Fe in solution. Therefore no pretreatment of Iron is needed which greatly decreases the loss of Ni. To regenerate LSC495, sulfuric acid was used, no-saponification process therefore decreases the overall OPEX.

The most important is that yield of resins to Ni being over 98%, which significantly decreased overall Nickel loss

Sunresin has a lot knowledge for solvent extraction, LSC 495 Bis-picolylamine Resins supplied another technical route for customer choices on nickel recovery.

As per the site conditions, below different chelating resins could be used in this applications.

Besides resins, Sunresin supply solution package including process design, equipment, pilot running etc

With same capacity, Sunresin SMB(stimulating moving bed) could greatly reduce the total resin quantity loaded,which decrease the CPEX.
