AB  - This paper presents the results of theoretical assessment and a preliminary experimental investigation of the modified pyrometallurgical processing of metallic granulate obtained after mechanical treatment of waste printed circuit boards (WPCBs). The studied two-step process included oxidation of metallic granulate followed by pyrometallurgical refining in a DC arc-furnace. In the investigated process, the oxygen bounded in metal oxides, obtained during the oxidation annealing of granulate, was used as a "solid" oxidizer for subsequent pyrometallurgical refining in a DC arc-furnace. According to the obtained results, the Cu content in the produced metallic phase (anodic copper) was 98.4% and is suitable for further electro-refining process. In addition, over 94% of Au was concentrated in metallic phase, suggesting that a high Au yield could be attained. However, owing to the distribution between slag phase and filter product, only 60% of Ag was collected in the metal phase. In-between metal and slag is the metal-oxide phase, containing Cu with metals impurities, such as Sn and Pb, which was obtained as well, and could be further treated using conventional processes for additional metal valorization. The investigated concept would allow substitution of the long-lasting oxygen blowing process and application of complicated pyrometallurgical reactors and create a feasible alternative for lower operating capacities.

AB  - Wide application of hard metals requires increased consumption of their constituents. Their high cost and scarcity impose the need for finding new, both ecologically and economically justified ways for their production. In presented research, on the basis of previous research, a review of an integrated technological procedure of recycling and valorization of useful components from hard metals secondary raw materials is given. Integrated procedure for processing of hard metal's waste enables the preparation of a wide range of powders with required properties, a high efficiency and reducing the duration of individual stages of procedures for their processing. Therefore, besides conservation of natural resources there are also significant economic and energetic benefits. The developed technological procedure is in service of sustainable development.

AB  - This paper presents investigation of possibility of heavy metals contaminated solid wastes treatment form Bor Site, Serbia. Presented remediation technology is stabilization, which can effectively reduce content of contaminants in the environment. As a representative of solid waste from investigated site Dam from the Bor copper sulphide ore flotation tailings was chosen. For stabilization of solid waste as stabilizing agenses foundry sand and lime were used. Experiments were conducted by leaching of mixture of solid samples and stabilizing agens or their mixture with sulphuric acid. Change of Cu, Fe, Pb and Zn concentration and change of pH and Eh value were followed during 4 cycles of leaching. Laboratory results of stabilization show that used stabilizing agenses are very effective in stabilization of heavy metals in investigated waste samples.
