[]]["Neodymium Manget China X"|The New Gold Rush Fueled by Cell Phones and TVs}

Here's the reason they have not been mined in the US, where they are prevalent, especially at former gold and silver mine sites.Let's look at these "rare earth" elements in more detail. First, Neodymium is a silvery metal that tarnishes in air. Despite being considered a rare element, it is present in various parts of the world and no more rare than copper, nickel or cobalt. It is extremely useful in our modern world. Here are just a few of its uses when made into powerful, permanent magnets, according to Wikipedia. "These magnets are widely used in such products as microphones, professional loudspeakers, in-ear headphones, and computer hard disks, where low magnet mass or volume, or strong magnetic fields are required. Larger neodymium magnets are used in electric motors (for example in hybrid cars) and generators (for example aircraft and wind turbine electric generators".

Praseodymium is used to color glass and also has magnetic, chemical, electrical and optical properties. It is used in industry to filter yellow light from light sources. Cerium is used in fluorescent lights and is the most abundant of all the rare earths, according to Wikipedia. "Commercial applications of cerium are numerous. They include catalysts, additives to fuel to reduce emissions and to glass and enamels to change their color. Cerium oxide is an important component of glass polishing powders and phosphors used in screens and fluorescent lamps. It is also used in the "flint" (actually ferrocerium) of lighters."Lastly there is Lanthanum, often found in combination with Cerium. " Lanthanum compounds have numerous applications as catalysts, additives in glass, carbon lighting for studio lighting and projection, ignition elements in lighters and torches, electron cathodes, scintillators, tig welding electrodes, and others. Lanthanum carbonate (La2(CO3)3) has been approved as a medicine for treating renal failure.""The reason they haven't been explored for in the U.S. was because as long as China was prepared to export enough rare earths to fill the demand, everything was fine - like with the oil cartels. When China began to use them as a political tool, people began to see the vulnerability to the U.S. economy to having one source of rare earth elements," said Ian Ridley, director of the USGS Central Mineral and Environmental Resources Science Center in Colorado.Two years ago, China raised prices - in the case of Neodymium, used to make Prius electric motors stronger and lighter, from $15 a kilogram in 2009 to $500 in 2011, while Dysprosium oxide used in lasers and halide lamps went from $114 a kilogram in 2010 to $2,830 in 2011. It's also about the time China cut off supplies to Japan, maker of the Prius, in a dispute over international fishing territory.

This will provide new jobs and stop the monopoly China has enjoyed. It seems ironic that the new miners will be going through the tailings of old mines for rocks the original miners discarded. Perhaps some of these rare elements could also be recycled. super neodymium magnet sales, neodymium manget China, neodymium magnet suppliers
