Nickel Recycling by Magnesium Reaction of Fe-Ni Alloy Scrap

Abstract:

Ni recycling from Fe-Ni alloy scrap was successfully performed by Mg reaction and distilling process. Ni component in Fe-Ni alloy scraps dissolve selectively in molten magnesium metal and then vacuum distilling was applied to remove Mg from Mg-Ni liquid. Above 1,073K in dissolving stage, more than 99% Ni from scraps was recovered and under the distilling process at 1,273K, 10^-5 torr, the high quality Ni with 99.5% could be obtained. This study suggests the recycling process of Ni in Fe-Ni scrap with the combination of Mg reaction and distilling process.
