Neodymium is the most used of rare earth elements. Its demand is rapidly increasing as the raw material for Nd-Fe-B permanent magnets. In the present study, the preparation of neodymium metal by molten salt electrowinning was investigated, using the support salt of LiF:NdF3:BaF2 = 7.5:67.4:25.1 (in wt%, FLiNdBa). It focused.....

Korean J. Met. Mater. 2016;54(9):652-658.   Published online 2016 Sep 5
DOI: https://doi.org/10.3365/KJMM.2016.54.9.652

In this study, the effect of potassium persulfate on current efficiency for gold plating was investigated using electrochemical techniques. The current efficiency in the low-current-density range greatly decreased when potassium persulfate was added to the gold plating solution. However, the current efficiency in the high-current-density range did not change with..... More
