Uporedna analiza pirometalurških i hidrometalurških procesa za reciklažu štampanih ploča – teorija i praksa
Comparative analysis of pyrometallurgical and hydrometallurgical processes for PCB recycling – theory and practice
The production of e-waste from old computers increased by about five times, and from discarded mobile phones almost 20 times by the year 2020 compared to the year 2007. E-waste (electronic waste) is one of the fastest growing types of waste in the world, about 40-50 million tons per year in the last decade, representing 2-3% of the total waste generated annually worldwide. Printed circuit boards (PCBs) are the most valuable components of E-waste. The aim of this paper is a comparative analysis of pyrometallurgical and hydrometallurgical processes for the recycling of precious metals from PCBs based on experimental research and results.
Elektronski otpada od starih računara povećala se za oko pet puta, a sa odbačenih mobilnih telefona gotovo 20 puta za 2020. Godinu u odnosu na 2007. E-otpad (elektronski otpad) je jedna od najbrže rastućih vrsta otpada na svetu sa oko 40-50 miliona tona godišnje u poslednjoj deceniji, što predstavlja 2-3% ukupnog otpada koji se godišnje generiše širom sveta. Štampane ploče (PCB) su najvrednije komponente E-otpada. Cilj ovog rada je uporedna analiza pirometalurških i hidrometalurških procesa za reciklažu plemenitih metala iz PCB na osnovu eksperimentalnih istraživanja i rezulta
