Rare earth metals are minerals with specific characteristics of seventeen chemical elements in the periodic table. Smartphones are full of rare earth minerals and the biggest producer of these rare earth minerals is China. But the most minerals are found in Africa south Asia and the Middle East where it´s bought very cheap.

Smartphones chips are little, strong and filled with allot of high-tech. More cores, higher beat and more accumulator since a few years the two manufacturer Intel and AMD tried to make the best, strongest and fastest CPU (Central Processing Unit).

However, rare earth elements are only found in commercially viable amounts in several areas of the world. And then they were processed by Chinese worker because the production in the US will cost about ½ more than in China and in poor Countries there less stringent environmental regulation!

 Rare earth metals are used for wind turbines, hybrid cars, and night-vision goggles. Minerals like Neodymium are used in magnets to make speakers vibrate to create sound it´s often used in Headphones. Europium is a phosphor that creates a bright red on an iPhone screen. Rare earth elements are in nearly every  part of your phone, from the glass display, making it harder, to magnets in speakers, headphones, and vibrating motors, making them more powerful despite their small size Rare earth minerals are not easy to mine.

UnbenanntEvery Phone contains a few rare earth minerals and so it is possible to recycle them but it is very complicated and costs allot! So the most old Smartphones are toss away. Rare earth minerals are not the only valuable metals in your smartphone. There are other minerals like copper, gold, palladium, and platinum in your cell phone. If you are going to recycle your old phone only 1% of it will be reused.
