AB  - This paper demonstrates possibility of separate zinc and lead recovery from coal composite pellets, composed of EAFD with other synergetic iron-bearing wastes and by-products (mill scale, pyrite-cinder, magnetite concentrate), through a two-stage process. The results show that in the first, low temp erature stage performed in electro-resistant furnace, removal of lead is enabled due to presence of chlorides in the system. In the second stage, performed at higher temperatures in Direct Current (DC) plasma furnace, valorisation of zinc is conducted. Using this process, several final products were obtained, including a higher purity zinc oxide, which, by its properties, corresponds washed Waelz oxide.

AB  - This paper presents investigation of possibility for electric arc furnace dust (EAFD) and electronic waste (e-waste) valorization trough stabilization process, in order to achieve concurrent management of these two serious ecological problems. EAFD is an ineviTab. waste material coming from the electric arc furnace steel production process, classified as a hazardous waste. Furthermore, it is well known that residual materials generated in the e-waste recycling process, like LCD (Liquid crystal displays) waste glass, are not suiTab. for landfill or incineration. In this study, these two materials were used for investigation of possibility for their valorization in ceramic industry. Thus, an innovative synergy of waste streams from metallurgical and e-waste recycling industry is presented. Investigation included a complex characterization of raw materials and their mixtures, using chemical methods, optical microscopy, scanning electron microscopy, as well as methods for determining the physical and mechanical properties. Based on these results, it was found that material suiTab. for use in ceramics industry as a partial substituent of quartzite and fluxing components can be produced. Besides solving the environmental problem related to EAFD and LCD disposal, by replacement of raw materials certain economic effects can be achieved.

AB  - Present paper represents a methodology for establishing a relationship between the composition of mixtures of iron-bearing non-standard dispersed raw materials for production of sinter and its most important metallurgical properties, in accordance with the appropriate phase of the production technological process. Using an appropriate software package, the database of available resources is formed. Raw data in the database include: chemical composition, bulk density, grain size distribution, moisture content and the annual quantity generated. The base is divided into basic raw materials and additives. Basic, iron-bearing, raw materials are electro-arc furnace dust (EAFD), pyrite cinder and mill scale, and additives are: flux (lime), binders (cement, bentonite) and reducer (coke). For the study of these relations the planned experiment is conducted, based on the Simplex plane. The connection between the composition of the dispersed iron-bearing mixture, as an independent variable, and dependent variables (metallurgical properties such as resistance to impingement and compression strength) was determined using correlation and regression analysis, where mathematical models for fast and reliable projected synthesis the required metallurgical properties of sinter were obtained.

AB  - Steel scrap recycling is generally performed by direct smelting of scrap in an electric arc furnace, generating about 2% of dust per charge. Electric arc furnace dust (EAFD) is characterized as a hazardous material, due to its heavy metals content and a powder form. A present study indicates the possibility of domestic carbon steel EAFD stabilization by using cement as the main stabilizer; fly ash as an additive, and controlling the EAFD particle size by milling. EAFD replaced 0-50 % of fine aggregate and fly ash replaced 10-25% of cement in mixtures, with different milling times applied. S/S samples were tested for compressive strength and heavy metals leachability. The results of compressive strength testing showed that the maximum EAFD replacement is 15%, after which compressive strength decreases rapidly. The best fly ash compressive strength was attained at 10% replacement of both fine aggregate and cement. The milled EAFD produced the best results at three hours of milling, however, the addition of fly ash resulted in a slight compressive strength decrease in these samples. The TCLP analysis of concrete samples indicated that Zn and Pb were stabilized in the cement matrix even at 30% of fine aggregate replacement with EAFD. From the physical-mechanical and environmental aspects, EAFD can be used as a component in cement Mixtures in instances when the Zn and Pb content is not sufficiently high for justifiable valorization of these metals.
