Thought the history of civilisation, humanity has exploited an ever increasing repertoire of metals in our tools and technology. Copper and bronze, iron and steel, gold, silver, aluminium, tungsten, and so on.
Nowadays, we carry around in our pocket a huge range of metals — not just coins, but your smart phone in fact encapsulates an incredible selection of different metals, some pretty rare in Earth’s crust. The US Geological Survey has produced this amazing infographic of all the minerals and metals contained within the advanced electronics in your phone and other devices. Each material is selected for its particular combination of properties needed for the different functions within electronics. And these are sourced from mines all over the planet. Who’d have thought that we use such a range of materials everyday of our lives without even realising!
