Mobile devices have become indispensable tools for people, it is almost impossible to think that there is none in the house.

Over time, manufacturers have created simplified designs, making them thinner and with longer screens.

Although people know how cell phones work, they are often unaware that they are made of minerals, even in their electronic circuits.

An important part of these devices is the battery, which users demand a longer life.

Sicilia and copper are among the most common elements found all over your mobile device. In the case of the battery, lithium is part of it, although other technologies consisting of silicon and carbon have also started to be implemented, which offer other advantages.

In the case of silicon and carbon batteries, they offer greater capacity to store energy and extend service life. In addition to being less unstable than lithium, the chance of explosion is also reduced.

Another element is coltan, the combination of columbite and tantalite. Its most famous use is for making capacitors.

The extraction of elements has been fiercely criticized due to the fact that the cases of exploitation in African countries are due to the fact that the extraction has to be manual.
