The anatomy of a mobile phone.
Weighing around 160 grams, smart phones are made up of around 30 elements, including copper, gold and silver for wiring, and lithium and cobalt in the battery. The touch screen and display use indium, boron and rhodium. The circuits and chip use silicon, bismuth, gallium and gold. The camera and microphone use rare earths including neodymium, dyprosium and praesodymium. The vibration motors use tungsten and micro capacitors use tantalum.
A complex mixture that has to be extracted from the earth and processed to make the materials, before being then made into components, and sub-assemblies that are assembled into your phone, packaged, transported across the globe and then sold.
