THE TREASURES OF PRINTED CIRCUIT BOARDS IN CELL PHONE SCRAP AND THE DANGERS OF CONCERN

الملخص

Telephones play a greater role than ever in global use and the modern telephone industry depends on a
variety of resources consisting largely of precious and rare metals, and it is true that some of these mineral
sources are common and still available, such as iron ore and aluminum, but others such as Cobalt and
indium, these are rare elements and will not last long at current rates of consumption. The problem with the
foregoing is that the extractive industries extract irreplaceable mineral resources from the earth‘s crust,
where the use of mineral resources is closely related to technology, energy and the environment, and usually
causes disturbances in one field and the presence of disturbances in the other, and the use of motivational
devices from phones requires minerals Of the platinum group, which is a valuable and irreplaceable natural
resource, moreover, the short lifespan of mobile phones leads to an increase in electronic waste from phones,
and because the recycling systems are very low, it follows that scrap waste from phones goes to public waste
streams and thus The precious metals contained in that electronic scrap are lost, and this is first, and
secondly, this waste has become a cause for concern because of the elements and components it contains
that cause environmental pollution and various health diseases. In this study, the components of phones and
vehicles were reviewed and how to recycle printed circuit boards. Which are found in mobile phone scrap.
