Abstract

Električna i elektronska oprema (EE oprema) već duže vremena spada u najrašireniju industriju na svijetu. Kako raste proizvodnja tako raste i količina otpada koju je potrebno zbrinuti. Najveće količine električne i elektronske opreme obuhvaćaju mobilne telefone, kojih je sada već oko sedam milijardi, a svake godine se očekuje sve veća količina mobilnih telefona, od kojih će većina nakon korištenja biti odložena na odlagalište otpada. U ovom radu opisani su dijelovi mobitela, njihove količine te metode izdvajanja korisnih metala. Prema dobivenim rezultatima, vidljivo je da se elektrostatičkom separacijom ne mogu dobiti zadovoljavajući rezultati. Koncentracijski stol se pokazao dobrim uređajem za izdvajanje metala, s tim da bi se moglo postići i daljnje izdvajanje određenih vrsta metala ostalim metodama separacije.

Abstract (english)

Abstract: Electrical and electronic equipment (EEE) has been one of the widest spread industries in the world for quite a while. As production grows so grows the amount of WEEE (Waste electrical and electronic equipment). The greatest amount of electrical and electronic equipment includes mobile phones which have been over seven billion pieces so far and an increase of their number is to be expected every year and most of them ending up on waste disposal after being used. In this paper the pieces of cell phones, their amount and the method of extracting useful metals are described. According to the results, it is obvious that it is not possible to get satisfactory results by electrostatic separation. Shaking table has proved as a good device for extracting metal and there could be a further isolation of certain types of metal achieved by other methods of separation.
