operating and capital cost of the project by eliminating the
need for an on-site sulphuric acid plant.
Looking ahead, the potential impact of this tech-
nology on the REE industry, especially in the context of
global sustainability and national sovereignty, is cautiously
optimistic. The process’s ability to recover critical technol-
ogy metals with higher efficiency and lower environmen-
tal impact is a promising step towards a more sustainable
future. Moreover, the economic viability of this process in a
fluctuating market and its adaptability to different ore com-
positions will be crucial for its long-term success. The suc-
cessful commercial implementation of this process could
lead to a more secure and environmentally friendly supply
of rare earth elements, crucial for technological advance-
ments and green technologies.
In summary, while there are hurdles to overcome, the
progress made in this project paves the way for more effi-
cient, cost-effective, and environmentally friendly REE
extraction methods. The future, while not without its
challenges, looks promising for the field of rare earth ele-
ment recovery, with this innovative approach leading the
charge.
