Conclusion
On the basis of experimental results it can be concluded that properties of
investigated material is in accordance with literature and it could be a representative for
selection of proper hydrometallurgical recycling technique. AAS chemical analysis has
shown that fraction above 5 mm contained high amount of Fe and should be avoided by
more efficient magnetic separation. Also, -0.1 mm fracton can cause various difficulties
in process, great loses due to large content of metals in this fraction and decreased
leachability.
Final selection of the process which could be applied for further analysis
depends on input materials characteristics. There is no completely green option.
Selection of suitable hydrometallurgical process highly depend on leaching tests and
techno-economical analysis and possible solution for electronic waste lies in
combination of proposed process options.
