Interviews: Ask CMI Director Alex King About Rare Earth Mineral Supplies 62
The modern electronics industry relies on inputs and supply chains, both material and technological, and none of them are easy to bypass. These include, besides expertise and manufacturing facilities, the actual materials that go into electronic components. Some of them are as common as silicon; rare earth minerals, not so much. One story linked from Slashdot a few years back predicted that then-known supplies would be exhausted by 2017, though such predictions of scarcity are notoriously hard to get right, as people (and prices) adjust to changes in supply. There's no denying that there's been a crunch on rare earths, though, over the last several years. The minerals themselves aren't necessarily rare in an absolute sense, but they're expensive to extract.
The most economically viable deposits are found in China, and rising prices for them as exports to the U.S., the EU, and Japan have raised political hackles. At the same time, those rising prices have spurred exploration and reexamination of known deposits off the coast of Japan, in the midwestern U.S., and elsewhere.
Alex King is director of the Critical Materials Institute, a part of the U.S. Department of Energy's Ames Laboratory. CMI is heavily involved in making rare earth minerals slightly less rare by means of supercomputer analysis; researchers there are approaching the ongoing crunch by looking both for substitute materials for things like gallium, indium, and tantalum, and easier ways of separating out the individual rare earths (a difficult process). One team there is working with "ligands – molecules that attach with a specific rare-earth – that allow metallurgists to extract elements with minimal contamination from surrounding minerals" to simplify the extraction process. We'll be talking with King soon; what questions would you like to see posed? (This 18-minute TED talk from King is worth watching first, as is this Q&A.)

These are excellent examples of why, over the medium and long term (10+ year granularity) prices in these things tend to come down, rather than become problematic and scarce. It isn't just finding more, it's finding substitutes and alternatives all along the path of progress.

Shortage exists when demand exceeds supply. For many truly-rare elements, the cost has always been so high that the demand never took off, avoiding a shortage situation.

We have to differentiate between economic and true shortage. Economic shortage only means that it is currently, at this market price, unfeasible to pursue to exploit some sources. With most of the stuff we call "rare" or where we detect a "shortage", all it means is that at the current market situation it is not possible to produce more of this stuff. There is more, but the price would have to rise to make it economically viable to exploit the source.
That has happened and will happen. If we need some material, we will have to pay the price to mine it, drill for it or otherwise produce it. And once the price rises, deposits that are currently uninteresting will become viable.

Rare earth elements are not really as rare as the name implies. The deposits can be hard to identify and access but there are plenty of sites that can be utilized to increase domestic production.

My understanding revolves around only the crudest idea about modern mining methods and the resulting tailings & water usage they often employ. I assume that in China, they get around these costs by just damaging the environment (like dumping tailings where ever instead of having dedicated settling and filtering ponds). Could you give us some back of the envelope calculations (they could be percentages or additional yearly operating costs) of what these environmental regulations mean for mining operations in the United States versus China? There's an awful lot of talk on Slashdot and other news sites about how cost prohibitive the EPA makes business in America but I've never seen an expert in the industry actually talk hard numbers. Any ballpark estimates would be greatly appreciated. In your experience, are any of these laws and regulations less or more effective than others?
