Integralni hidrometalurški postupak reciklaže iz električnog i elektronskog otpada sa tehno-ekonomskim aspektima

Abstract

This doctoral dissertation, presents the results of the extensive analysis of technological, economic and environmental parameters influencing the development of integrated hydrometallurgical process of selective metals recovery from mechanically treated waste printed circuit boards (WPCB), using simple hydrometallurgical operations. The study was conducted trough characterization of WPCB granulate, investigation and optimization of various process parameters as well as characterization of products obtained. Tests were conducted trough five phases which included: thermodynamic analysis of possible reactions, laboratory tests of optimization and pilot level verification, definition of integrated hydrometallurgical process, techno-economic analysis of the defined process and finally a proposal of treatment of final non-metallic residue. Investigation conducted in order to optimize process parameters for selective metals recovery, was systemized by analyzing the three groups of metals which are characterized by hydrometallurgical compatibility (base, solder alloy and precious metals), and the results are presented in tabular and graphical form...

U doktorskoj disertaciji, su prikazani rezultati analize tehnoloških, ekonomskih i ekoloških uticajnih parametara na mogućnosti razvoja integralnog hidrometalurškog postupka selektivnog dobijanja metala iz mehanički tretiranih otpadnih štampanih ploča, primenom konvencionalnih hidrometalurških operacija. Ispitivanje je sprovedeno karakterizacijom polaznog granulata, ispitivanjem uticaja i optimizacijom različitih procesnih parametara, kao i produkata dobijenih različitim postupcima tretmana. Ispitivanja su sprovedena kroz pet faza koje su obuhvatale: termodinamičku analizu mogućih reakcija, laboratorijske testove optimizacije i potvrdu izvodljivosti optimizovanih procesa na pilot nivou, definisanje integralnog hidrometalurškog postupka, tehno-ekonomsku analizu definisanog postupka i konačno predlog postupanja se krajnjim nemetaličnim ostacima...
