Abstract. This paper represent the part of much larger research
of the treatment of aluminium slag which is defined as the dangerous waste
according to Yugoslav and international regulations. Untreated aluminium
slag is contaminating environment (water, air and earth) by emission
of liquid and gaseous phases of dangerous maters.
Experimental investigation shown in this paper are representing new
technology of treatment of aluminium slag by converting it into the useful
products and eliminating generation of dangerous and harmful maters. Efficiency
of eco-technological procedure is approved by modern fundamental methods
of chemical and physico-chemical analyze. It is obtained glass-ceramic
characterized by large contents of alumo-silicates and the structure of
it is approved. Such a new eco-technological procedure of the process of
treatment of aluminium slag is enabling complete protection of environment
together with using slag as secondary raw material. This is in accordance
with the recent trends in recycling and regeneration of waste.

NOVI EKO-TEHNOLOŠKI POSTUPAK
PROCESA PRERADE ALUMINIJUMSKE ŠLJAKE NASTALE TOPLJENJEM
I LIVENJEM ALUMINIJUMA I NJEGOVIH LEGURA
Ovaj rad predstavlja deo mnogo obimnijeg istraživanja prerade aluminijumske
šljake, koja se prema našim i svetskim kriterijumima svrstava u grupu opasnog
otpada. Neprerađena aluminijumska šljaka vrši sveobuhvatno zagađivanje
životne sredine (vode, vazduha i tla) emisijom tečnih i gasovitih faza
opasnih materija.
Eksperimentalna istraživanja prezentirana u ovom radu prikazuju novu
tehnologiju prerade aluminijumske šljake u korisne proizvode uz eliminisanje
pojave opasnih i štetnih materija u životnoj sredini. Efikasnost eko-tehnološkog
postupka je egzaktno dokazana najsavremenijim fundamentalnim metodama hemijske
i fizičko-hemijske analize. Dobijena je staklo-keramika koju karakteriše
visok sadržaj alumo-silikata i njena struktura je potvrđena. Ovakav novi
eko-tehnološki postupak prerade aluminijumske šljake omogućava potpunu
zaštitu životne sredine uz korišćenje šljake kao sekundarne sirovine, što
u potpunosti poštuje savremene tendencije reciklaže i regeneracije otpada.
