Hydrometallurgical Process For Extraction Of Metals From Electronic Waste-Part Ii: Development Of The Processes For The Recovery Of Copper From Printed Circuit Boards (Pcb), Zeljko J. Kamberovic
Hydrometallurgical Process For Extraction Of Metals From Electronic Waste-Part Ii: Development Of The Processes For The Recovery Of Copper From Printed Circuit Boards (Pcb), Zeljko J. Kamberovic
Zeljko J Kamberovic
Rapid technological development induces increase of generation of used electric and electronic equipment waste, causing a serious threat to the environment. Waste printed circuit boards (WPCBs), as the main component of the waste, are significant source of base and precious metals, especially copper and gold. In recent years, most of the activities on the recovery of base and precious metals from waste PCBs are focused on hydrometallurgical techniques as more exact, predictable and easily controlled compared to conventional pyrometallurgical processes. In this research essential aspects of the hydrometallurgical processing of waste of electronic and electrical equipment (WEEE) using sulfuric acid …

Used electronic equipment became one of the fastest growing waste streams in the world. In the past two decades recycling of printed circuit boards (PCBs) has been based on pyrometallurgy, higly polluting recycling technology whic causes a variety of environmental problems. The most of the contemporary research activities on recovery of base and precious metals from waste PCBs are focused on hydrometallurgical techniques as more exact, predictable and easily controlled. In this paper mechanically pretrated PCBs are leached with nitric acid. Pouring density, percentage of magnetic fraction, particle size distribution, metal content and leachability are determined using optical microscopy, atomic …
Optimisation Of Ferriferous Dust And Mud Preparation Acts From Iron And Steel Production On Purpose Of Returning To Primary Processes, Zeljko J. Kamberovic
Optimisation Of Ferriferous Dust And Mud Preparation Acts From Iron And Steel Production On Purpose Of Returning To Primary Processes, Zeljko J. Kamberovic

In this paper detailed characterization of ferriferous dust and mud which originated from aglomerization, blast- furnace and converter process in Iron-works Smederevo were shown. Optimization of method peletization was conducted in variably conditions (different moinsture content, changing of time of peletization and type of binder). These palets were submitted to examination of resistance on impact and pressure, and their behavior was confirmed returning in sintering process in semiindustrial conditions. Ideally-technological solution for plant preparation of dust and mud in Iron-works Smederevo was recommanded. That solution should contribute to improvement of techno-economic parametars of aglomeration and blast- furnace process, as well …
