ABSTRACT

At present the waste from iron- and steelmaking finds hardly applicability as secondary
raw material. Evidence has been given that the low-temperature plasma could replace
the existing routes of less-suitable pyrometallurgical treatment of such wastes that are
therefore processed by hydrometallurgical route.

As the metallurgical and technological features of this application are obvious then
more light should be thrown into the economy. The economical insight into efficiency
of the assumed processing of the metal-bearing waste is dealt in detail with by example
of a concrete situation at VITKOVICE HEAVY MACHINERY, a.s.
On the basis of a complex examination of trial results this work provided evidence on
metallurgical readiness and economical efficiency in implementation of plasma heating
at processing of the metal-bearing oxidic wastes under conditions prevailing in the
VITKOVICE HEAVY MACHINERY, a.s.

With reference to the previous investigation this paper present evaluation of the possible
ways of implementation of the plasma torch at processing refuse from the PET-bottles
and worn tyres. Verification of possible processing the PET-bottles and worn tyres with
utilization of the plasma technology is performed with original trial facility installed in
the working place common of the VŠB-TU Ostrava and Material and Metallurgical
Institute, s.r.o..
