Geological Society of South Africa, held in Johannesburg in 2013 annual meeting of the geological forums, Smith said at the meeting, "although the EU and the U.S. Department of Defense and fully agree with the metals are listed in the table key, but they do agree that this is a three 'the importance of the metal on the list of the most forward'.

So far, outside of China, there are 15 countries from 51 rare earth-related vision. Smith adds that although these projects primary issue is access to capital and separation of rare earth expertise. Around this problem, many countries, including South Africa, is investigating the possibility of establishing centralized separation plant.
