- •
A thermodynamic model was employed to define the optimum experimental conditions.
- •
Highest nickel grade of 9.2% was achieved in argon, with a recovery of 89%.
- •
In argon, high recoveries were achieved at lower energy inputs than without argon.
- •
Enrichment ratios achieved were greater than those reported in the literature.
