Scientific Reports published this week set out the discovery of a seemingly indefinite deposit of yttrium, europium, terbium and dysprosium that exists off the coast of Japan.

Intensive boiling with strong acids — repeated thousands of times because the elements are so chemically similar — finally separates out the neodymium, dysprosium or cerium.

Strong attractor But, in large part, magnets drive the growth in demand for rare earths such as neodymium — swelling by 15 percent per year, according to an analysis published in Science — and dysprosium.

As it stands, 97 percent of the 124,000 metric tons of neodymium, dysprosium — the name means «hard to get» — and other important rare earth elements produced each year come from one place: China.
