Nov 18, 2013 · another option is to make the mining processes more efficient. for rare earths, says king, mining companies basically grind up the rock, throw it in water, and blow bubbles through it: the rare-earth-bearing minerals tend to float and can be skimmed off the top. but this only captures about 65 percent of the rare earths in an ore, says king.

Rare earth metals are at the core of every major technology today. smartphones, laptops, wind turbines, electric cars, and medical devices — you name it. they're also widely used in defense technology, like jets and guided missile systems. neodymium, dysprosium, praseodymium, and terbium, for ...

Oct 17, 2017 · “rare earth elements occur in ores in very small concentrations, a few thousand parts per million. extensive processes of mining, grinding, extraction, and purification are needed to transform the ores to very high purity (approximately 99.9 percent minimum) rare earth metals required for commercial applications,” she said.
