The battery in a single Toyota Prius contains more than 20 pounds of the rare earth element lanthanum; the magnet in a large wind turbine may contain 500 pounds or more of neodymium.

Rare-earth magnets are used in computer hard disks and CD–ROM and DVD disk drives. The spindle of a disk drive attains high stability in its spinning motion when driven by a rare-earth magnet. These magnets are also used in a variety of conventional automotive subsystems, such as power steering, electric windows, power seats, and audio speakers."

However, a lack of rare earths does not mean that the components of solar modules are harmless. Thin-film PV technologies, for example, contain potentially critical metals such as tellurium ...

The study showed that it is possible to obtain red mud that contains three times more REE than traditional waste red mud after two-stage leaching ESP dust in the water at 95 °C followed by leaching in an alkaline-aluminate liquor at 240 °C. The shrinking core model was used …

The United States' annual rare earth demand stands at around 12,000 to 13,000 metric tons. "Very rough estimates tell us if we could extract 100 percent of the rare earths from each of these ...

"Rare earths" are a group of 17 chemically similar elements crucial to the manufacture of many hi-tech products. Despite their name, most are abundant in nature but are hazardous to extract. Most ...

U.S. Geological Survey news release "Going Critical". The rare earth elements (REE) are a set of seventeen metallic elements. These include the fifteen lanthanides on the periodic table plus scandium and yttrium. Rare earth elements are an essential part of many high-tech devices. The U.S. Geological Survey news release "Going Critical" explains:
