Did you ever wonder how your iPhone screen got its color? It's from rare-earth minerals. CNET's Jay Greene takes you on a tour of a rare-earth mineral mine in California, where you'll see firsthand how rocks become the pixie dust that powers your iPhone.
Molycorp said Mark Smith's departure from the company, which mines minerals that are crucial ingredients for mobile phones, was unrelated to a regulatory investigation into the company's public disclosures.
How are these unusual minerals extracted from the ground and why is that process an environmental risk? CNET's Jay Greene explains.
Molycorp, which plans to officially reopen its rare-earth mine in California this week, buys a company which can manufacture neodymium-based alloys for permanent magnets from the minerals it mines.
Molycorp Minerals seeks to reopen a California mine to extract rare earth elements, a group of metals used for magnets and batteries in hybrid vehicles, wind turbines, and other green technologies.
But China says it regrets the WTO's decision, a ruling that could have implications for the legality of the country's rare-earth export quotas. China insists its policies are based on environmental and resource protection.
The Energy Department issues a report that outlines the risks from being overdependent on China for minerals considered crucial for high-tech products and clean-energy technologies.
Republic reduces its first batch of rare earth export quotas for 2011 by more than 11 percent, in the face of a threat by the U.S. to complain to the WTO over the limits.
The planned joint venture would bring manufacturing of rare earth alloys and magnets to the U.S.
It was once an obscure topic only for geologists. But China's control over rare earth elements used in green- and high-tech equipment is causing alarm as the nation cuts exports.
