Predmet istraživanja ove doktorske disertacije predstavlja analizu uticaja veoma
bitnih parametara procesa topljenja sulfidnih koncentrata bakra: sadržaja bakra u
bakrencu, sastava šljake i baziciteta šljake, na distribuciju bakra i pratećih elemenata
između šljake i bakrenca. Objašnjen je mehanizam gubitka bakra u šljaci, zajedno sa
drugim obojenim, retkim i plemenitim metalima i izvršena je statistička analiza uticaja
sastava šljake i sadržaja bakra u bakrencu na ukupne gubitke bakra u šljaci, na osnovu
čega su razvijeni matematički modeli koji opisuju ove uticaje. U narednim poglavljima
je na osnovu ekstremno visokih koncentracija SO2 i PM polutanata, izmerenih u
urbanom delu grada Bora, kao posledice emisija topioničkih dimnjaka, izvršeno
rangiranje lokacija na osnovu njihove zagađenosti i utvrđeno je da se najkritičnija zona
nalazi u samom centru grada.
Statistička obrada podataka je vršena primenom multivarijantnih i nelinearnih
metoda u svrhu modelovanja procesa, dok... je metoda višekriterijumskog odlučivanja
primenjena u svrhu rangiranja lokacija po njihovoj zagađenosti. Za potrebe istraživanja
korišćeni su podaci prikupljeni nakon opsežnog uzorkovanja kao i na osnovu posebno
organizovanog eksperimenta, pri stabilnim industrijskim uslovima topljenja koncentrata
bakra u plamenoj peći topionice RTB – Bor.
Rezultati, predočeni u ovom radu, mogu biti od pomoći prilikom upravljanja
ekonomskim i ekološkim aspektom proizvodnje bakra, omogućavajući bolje
razumevanje faktora koji utiču na distribuciju metala odnosno gubitke bakra i ostalih
korisnih elemenata u toku procesa topljenja bakarnih koncentrata
The subject of this dissertation is the analysis of the influence of very important
parameters of the melting process of copper sulphide concentrates: copper content in
matte, the composition of slag and slag basicity, on the distribution of copper and
accessory elements between the slag and the matte. Mechanism of copper loss in the
slag, together with other non-ferrous, rare and precious metals is explained and
statistical analysis of the influence of the slag and the copper content in the matte on the
total losses of the copper in the slag was performed, based on which mathematical
models were developed which describe these effects. In the following chapters, based
on the extremely high concentration of SO2 and PM pollutants measured in the urban
part of the city of Bor, as a result of emissions of smelter stacks, ranking of locations
was performed based on their contamination and the most critical zone was found to be
located in the town center.
Statistical analysis was... performed using multivariate and nonlinear methods for
processes modeling, while the method of multicriteria decision making was utilized for
ranking locations according to their contamination. The data used in the research was
collected after extensive sampling and from specially organized experiment, under the
stable industrial conditions of smelting of copper concentrates in the reverberatory
furnace of the RTB - Bor smelter.
The results presented in this paper, can be helpful in managing the economic and
environmental aspects of production of copper, allowing a better understanding of the
factors that influence the distribution of metals or losses of the copper and other useful
elements in the process of smelting of copper concentrates.
