To conclude, the supply risk issue of Nd and Dy is found to be a
bottleneck issue of opening new mines at an accelerated rate to
satisfy the future high demand in the period from now until
2050. Our results indicate that the potential mining projects
outside China do not have high content of Dy as China possess
around 70% of the currently known Dy reserves. This suggests
that China is very likely to play its dominant role for Dy primary
supply in the short-to-medium term future until recycling
provides significant secondary supply to reduce the contribution
of mining in order to meet the future demand.
