Poštovane koleginice i kolege,

Laboratorija za gasnu elektroniku
Vas sa zadovoljstvom poziva na seminar dr Aleksandra Mitrašinovića U
SREDU, 11.1.2012. U SALI 10. SA POČETKOM U 13H.

Naziv seminara je
"Recovery of valuable metals from E-waste using thermal plasma
treatment." 

Dr. Aleksandar Mitrasinovic, formerly Ph.D. student with
the Department of Materials Science and Engineering, University of
Toronto, is currently a Materials Scientist with the Centre for Advanced
Coating Technologies (CACT), University of Toronto and Postdoctoral
Fellow with Laboratory for Emerging Research (LEER), University of
Waterloo, Waterloo, ON, Canada.

Abstract:

A thermal plasma treatment
was employed for economical recovery of valuable metals from e-waste.
Cu-clad plates that simulated circuit boards were fed at the bottom of
the reactor and treated with a plasma jet at temperatures between 385
and 840oC. Organic components of the Cu-clad plates were decomposed and
contributed to the increased temperature of the offgas. Due to the low
temperatures at the base of the reactor, the analyzed samples did not
show losses characteristic for the plasma processes such as evaporation
or metal oxidation. After plasma treatment, Cu foils were separated from
the fiber glass and other solid residues allowing a complete recovery.
Solid residues of the plates at the bottom of the reactor were crunched
into small particles, allowing easy recycling or use as construction
material.

Srdačan pozdrav,

LGE.
