Mainland grip on rare earths limits free trade, Reuters in Washington (Sep 23, 2010)

The mainland's grip on the rare earths market shows the limits of free trade. The country's producers dominate the market, and a 72 per cent cut in export quotas for the second half of this year has sent global prices soaring. That is a blow to high-technology industrial users of the metals elsewhere - and a reminder that the assumptions that make globalisation beneficial can easily be thrown off.

Rare earths, a group of 17 metallic elements including yttrium and lanthanum used in small quantities to enhance batteries, computer and weapons systems, and other applications, are generally found together.  The United States was a major producer until the 1990s, but environmental concerns and low prices caused the closure of the Mountain Pass mine, the main US source, in 2002.

Since then, China has been the dominant source of rare earths, accounting for 97 per cent of world supply last year.Because of the technological applications, demand for rare earths is increasing rapidly from the 120,000 tones used last year. Much of the value added comes from their fabrication into batteries and other products.

The mainland's quota cut appears to have been motivated by a desire to increase its companies' share in these industries.
The quota cuts combined with rising demand have led a number of rare earth oxides to double or almost double in price this year. That has produced a rush to find other sources of supply, including plans for the full reopening of Mountain Pass and the redevelopment of an old mining area in South Africa - although both will take until 2012 at least.

It is tempting for China to risk such disruption for its own purposes. In the case of rare earths, the solution - other sources of production - is only a few years away. The danger is that in an uncertain global economy, the protectionist habit spreads.

About Yttrium (Rare Earth)

Yttrium (pronounced /ˈɪtriəm/ IT-ree-əm) is a chemical element with symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanoids and has historically been classified as a rare earth element.[2] Yttrium is almost always found combined with the lanthanoids in rare earth minerals and is never found in nature as a free element. Its only stable isotope, 89Y, is also its only naturally occurring isotope. Learn more
