AB  - This study presents the results of the theoretical assessment and a preliminary experimental investigation of technology metals (TM) recovery from magnetic fraction obtained after mechanical treatment of waste printed circuit boards (WPCBs). Experimental work included physical and chemical characterization, thermodynamic analysis, and pyrometallurgical tests corresponding to secondary lead, copper, and steel metallurgy. Technology metals recyclability and recovery potential were evaluated with respect to their distribution between metal and slag phase (difficult for recovering) versus the dust phase (easy for recovering). According to obtained results, it was determined that high-temperature processing of magnetic fraction in the electric arc furnace promotes volatilization of the TM and their pre-concentration in the filter as a dust product from which they could be valorized using further hydrometallurgical methods. © 2019, Association of Metallurgical Engineers of Serbia.

AB  - Silver fine powder with different shapes and sizes were prepared by chemical
reduction and characterized by scanning electron microscope. In this paper was
presented the method for the preparation of the fine Ag powder with particles size
smaller than 2.5 μm with suitability for the mass-production scale. Reduction was
performed from nitrate solution directly by vigorous stirring at room temperature by
three different reduction agents, with and without presence of two dispersants. Scanning
electron microscopy revealed the preferred size of the particles obtained in all
experiments with aim of the protecting agent. Larger particles and wider size
distribution were obtained without surfactants although with average size of about 1 μm
and small quantity of larger clusters of primary particles that is out of the fine powder
classification. High purity, 99.999%, of silver was obtained in every experiment.
