A couple of years back, when rare earth prices were high and China restricted exports, the media was full of scaremongering stories about how we gonna see our industry shut down, etc.
Turns out that prices are a strong signal to start mining. While rare earth sound like a scarce resources, they are essentially prevalent across the globe in very low concentration. The existing mines are usually places where the concentration is a tad higher. But once prices are high enough, a lot of marginal deposits all over sudden become commercially viable.

- aidenn0 9y agoWe hit peak oil later than planned because the rate of oil-consumption growth plummeted. The estimates were within an order of magnitude (which is a small margin of error you double your consumption every 20 years).
- Animats 9y agoThe problem is that the China price is politically motivated. It was cranked up to move motor production to China; exports of the raw material were restricted while motor exports were not. When that backfired, the price was dropped to maintain China's control of rare earth production.
