Recycling of printed circuit boards : master's thesis

Razvojem tehnologije raste potražnja za elektroničkim uređajima, koji ubrzo bivaju zastarjeli te postaju EE otpad. Svaki takav uređaj sadrži tiskane pločice kao sastavni dio, koje odbacivanjem postaju važna sekundarna sirovina iz koje recikliranjem možemo pridobiti važne materijale. U radu su prikazane glavne karakteristike elektroničkog otpada, te njegovo pravilno prikupljanje i recikliranje, kao i trendovi EE otpada u budućnosti. Uz ispitivanja provedena u cilju pronalaženja optimalnih postupaka za recikliranje tiskanih pločica metodama oplemenjivanje mineralnih sirovina utvrđeni su tehnološki pokazatelji separacije tih ispitivanja.Abstract: With the development of technology, demand for electronics is constantly increasing, therefore electronics quickly become outdated. Every device of this kind contains printed circuit boards as an integral part. With their disposal electronics become an important secondary raw material from which we can gain valuable recycling materials. The master's thesis describes the main characteristics of e-waste and its proper collecting and recycling, as well as the trends of e-waste in the future. Laboratory tests were performed in order to find the optimal processes for recycling printed circuit boards by mineral processing methods, and technological indicators of separation were identified
