Scientists have thoroughly studied the smartphone crushed in a blender (3 photos + video)

Recently it has become fashionable to experiment.with announced or marketed smartphones. New items are disassembled in order to understand what they are made of and whether it will be easy to repair them. However, a completely different task was set by specialists from the University of Plymouth. The researchers wanted to deal with the chemical composition of modern technology.

For testing, the experimenters chose notThe new model of the iPhone, which is ground in a blender. The fine particles thus obtained were mixed with sodium peroxide, which is a powerful oxidizing agent, for further study.

After analyzing the chemical composition of the mixture, scientistsfound out that the phone had 33 grams of iron, 13 grams of silicon, 7 grams of chromium and very few other substances. They were interested in the presence of 900 milligrams of tungsten, 160 milligrams of neodymium, 70 milligrams of molybdenum and cobalt, 90 milligrams of silver, 36 milligrams of gold and 30 milligrams of praseodymium among other things.

To extract such rare elements from the depths of the Earthit is necessary to extract significant amounts of ore. And this, according to researchers, causes considerable damage to the environment. Moreover, metals like cobalt or tungsten are usually supplied from African conflict zones. To produce 1 gadget, you will have to earn an average of 10 - 15 kilograms of ore, including 7 kilograms with gold, 1 kilogram with copper, 750 grams with tungsten, 200 grams with nickel.

The concentration of tungsten in the smartphone is tenfoldsurpasses the indicators of rocks, the concentration of gold, perhaps as much as a hundredfold According to researchers, this experiment shows how important the thoroughness of processing electronics, out of circulation.
