Rare Earth Prices Double on China Controls

Prices of the rare earths used in lasers and plasma televisions more than doubled in the past two weeks as China tightens control of mining, production and exports, according to market researcher Industrial Minerals.

The cost of dysprosium oxide, used in magnets, lasers and nuclear reactors, has risen to about $1,470 a kilogram from $700 to $740 at the start of the month, Industrial Minerals said in an e-mailed statement. Europium oxide, used in plasma TVs and energy-saving light bulbs, has more than doubled.

China, supplier of 95 percent of the 17 elements known as rare earths, has clamped down on rare-earth mining and cut export quotas, boosting prices and sparking concern among overseas users such as Japan about access to supplies. The government may further reduce export quotas, pushing prices higher, Goldman Sachs & Partners Australia Pty said last month.

“China has long said it will consolidate the industry but it’s moving more rapidly than many observers anticipated,” said Dudley Kingsnorth, a former rare earths project manager and now chief executive officer of Perth-based advisory Industrial Minerals Co. of Australia. “There might be an element of speculation but I think the price rises have been driven by people who are desperate for the product.”

The world’s most populous nation will raise standards for exporters and won’t approve new project expansions in an effort to curb overcapacity, illegal mining and sales, the government said last month. The Ministry of Land and Resources said yesterday it wants to set aside some rare earth deposits.

I wonder how much impact on final cost a doubling of a few essential elements would have on, say, a wind turbine?
