iPhones contain a number of different metals, including titanium, iron, and aluminum.
There is far for aluminum than any other metal in your phone — it makes up about 24% of an iPhone’s mass.
While rare earth elements comprise only a fraction of an iPhone’s mass, mining for these elements is a huge global business.

Your iPhone is a complex piece of machinery. Each phone contains a number of metals, including titanium, iron and gold.

There is far more aluminum — which is used to make your phone’s outer case — than any other metal, however.

Aluminum comprises around 24% of an iPhone’s mass, followed by iron, which makes up around 14% of the device’s mass, according to a breakdown from Motherboard. Copper and cobalt comprise around 6% and 5% of the phones mass.

Aluminum is one of the most abundant metals in the Earth’s crust, though it doesn’t exist in a pure state in nature. Instead, it’s produced by refining bauxite ore. Canada is the largest exporter of aluminum to the US, while China is the world’s biggest aluminum producer.

Rare earth elements like yttrium and europium are crucial to your iPhone’s function — they’re used in the phone’s battery, as well as to help give the display screen color and make the phone vibrate when you get a text, among other uses. Although they account for only a fraction of a percent of the phone’s total mass, these elements have made mining rare earth elements a huge business.

Japanese scientists recently found an underwater, ‘semi-infinite’ deposit of these elements, including valuable yttrium, off of Minamitori Island, about 1,150 miles southeast of Tokyo.

Expert’s say Japan’s cache could help revitalize the country’s flagging economy and put a dent in China’s trade monopoly.
