AB  - The importance of recycling the waste electrical and electronic equipment (WEEE), in recent years, has been taken into increasing concern and consideration not only by the government, but also by their hazardous material contents. Electronic waste can be defined as a mixture of various metals, particularly copper, aluminum and steel, with various types of plastics and ceramics. Recycling of electronic waste is an important subject not only from the point of waste treatment, but also from the recovery aspect of valuable materials. Pyrometallurgical processing has been a traditional technology for recovery of the precious metals from waste electronic equipment. In the past two decades, the most active research area on recovery of metals from electronic scraps is recovering the precious metals using the hydrometallurgical techniques. Compared with the pyrometallurgical processing, the hydrometallurgical method is more exact, more predictable and more easily controlled. In the last decade, the recovery of metals by biotechnology has been one of the most promising technologies. Biometallurgy has the potential for a major technology breakthrough for the materials and minerals industry due to a great interest shown by the major international companies for this new technology. Understanding the biochemical processes, involved in treatments of metals, has been the subject to growing investigations for the last 20 years. At present, the research and development are in progress for a number of metals such as copper, nickel, cobalt, zinc, gold and silver. However, the activity of leaching bacteria is applied for recovery of gold and silver only to remove the interfering metal sulfides from ore bearing the precious metals prior to the cyanidation treatment. Recent research trend is to use the combined methods for optimal results.

AB  - The aim of this study was a characterization of the crystals of gold complexes based on mercaptotrazole, obtained from solutions with different pH values (2, 4, 7, and 9), using the methods of infrared (IR) and Raman spectroscopy. Both methods provided very useful information on the investigated systems and signalized existence of the Au-S bond in the complexes obtained at pH = 2 and 9. Recorded spectra clearly illustrated the changes that occur in the systems as a consequence of pH change. At the same time, the results also showed that the pyrrole nitrogen atoms stay protonated at pH = 9, which is not in favor of the assumption evolved from the previous UV-vis analysis of possible additional coordination between Au and possible deprotonated nitrogen atoms at this particular pH.

AB  - This paper presents the method for preparation the fine Ag powder with a particles size smaller than 2 μm. Reduction was performed from the nitrate solution directly by the vigorous stirring at the room temperature by the use of ascorbic acid as the reducing agent and polyvinylpyridine as the protecting agent. Silver powder with nearly spherical particles and size of micrometers were prepared by the chemical reduction and characterized by the scanning electron microscope (SEM). The SEM analysis has shown that preferred size, less than 2 μm was obtained. Silver with purity of 99.9% or more was obtained.

AB  - The objective of this work was to investigate the stability of the gold complex based on
mercaptotriazole in slightly acid media, at pH=4. The gold complex complex was studied by the visual monitoring and electrochemical characterization of electrolytes in the period of three months.
Electrochemical characterization was performed by the open circuit potential measurement, cycling
voltammetry method and recording the polarization curves, with pH of the electrolyte measurement
before and after each electrochemical experiment. These tests, performed at pH=4 and optimal
concentration of gold in the electrolyte of 2.5 g/dm3, for a period three months, did not show any visual or other essential changes of investigated electrolyte characteristics.

AB  - This paper presents investigations of the influence of silicon addition on the mechanical and corrosion characteristics of the sterling silver Ag-Cu-Zn alloys. The procedure for obtaining Ag-Cu-Zn-Si alloys in small ranges of composition was also presented Vickers hardness tests and three electrochemical tests were performed on the samples in this study. Open circuit potential measurements, linear polarization resistance method, and potentiodynamic polarization tests were employed to determine corrosion characteristics of the alloys. The materials were tested in 0.9% Nacl solution, artificial sweat, 0.1 and 0.01 M sodium sulfide solutions. It was shown that addition of silicone increases hardness and generally improves sulfidation resistance and corrosion characteristics in near-neutral chloride solutions of the Ag-Cu-Zn alloys.

AB  - The aim of this work was to investigate the stability of the gold complex based on mercaptotriazole at optimum pH value of nine in the electrolyte with gold concentration of 1.5 g/dm3. Investigations were performed by visual monitoring and electrochemical characterization of electrolytes over the period of four months. The first visible signs of the decomposition of the complex were appeared one month after synthesis. Electrochemical characterization of gold complex base on mercaptotriazole performed by the open circuit potential measurement, cycling voltammetry method, and recording the polarization curves, with pH of the electrolyte measurement before and after each electrochemical experiment, showed that all the recorded characteristics remained almost unchanged for a period of four months.

AB  - The aim of this work was to investigate the effects of current density, temperature, pH and concentration of ethyl-hexilsulfonate additive on the microhardness of electrochemically deposited gold decorative coatings obtained from a conventional cyanide electrolyte and gold complex based on mercaptotriazole. Mechanically and chemically prepared brass samples were first nickeled from acidic electrolyte. Nickel was a substrate deposit, and then decorative gold coatings were deposited from two types of electrolytes at different current densities and temperatures. Decorative gold coatings were deposited from auri-mercaptotrizole at different pH values and from electrolyte with and without the ethylhexilsulfonate additive. The microhardness of the gold coating was measured using the Knoop method. The highest values of microhardness were obtained at a current density of 1 A dm(-2) at room temperature for both electrolytes. The microhardness of the gold coatings from cyanide electrolytes was HK = 740 MPa, and the coatings obtained from auri-mercaptotriazole HK = 660 MPa. This difference is not relevant for decorative purposes. The highest values of microhardness, HK = 660 MPa, were obtained at pH = 9 from the gold complex based on mercaptotriazole without the additive.

AB  - In this work, the possibilities of a mass spectrometry approach towards the characterizations of the electrolyte for decorative gold plating based on mercaptotriazole were studied. All mass spectra were obtained using laser desorption ionization (LDI) method on a commercial matrix assisted laser desorption ionization – time of flight (MALDI-TOF) mass spectrometer. The LDI MS spectra of chloroauric acid gave evidence of the presence of a variety of monomeric and polymeric complexes. LDI MS spectra of the electrolyte obtained from chloroauric acid, glycine and mercaptotriazole revealed existence of the ion at m/z 472 which indicated that the complex [Au(NH2CH2COOH)(C2H2N3S)2]- has been formed.

Investigations were performed by immersion the previously prepared boards in electrolytes with different pH values (pH=2, 4, 7, 9 and 12) at gold concentration of 2.5 g/dm3 and in gold complexes with different gold concentrations (1.5; 2.0; 2.5; 3.0 and 3.5 g/dm(3)) at pH value of pH=9. Investigations showed that photoresist layers on boards are the most resistant at optimal operating conditions, pH=9 and concentration of gold of 2.5 g/dm(3).

AB  - The aim of this work was to investigate the effect of temperature on the thickness, surface roughness, visual appearance and morphology of electrochemically deposited gold decorative coatings obtained from conventional cyanide electrolyte (AUROCIN DPB) and electrolyte based on mercaptotriazole (Au-MT). Heating of cyanide electrolyte does not significantly affect the thickness (b) of gold coatings (at 20 degrees C b = 0.08 mu m, at 30 degrees C b = 0.07 mu m and at 40 degrees C b = 0.08 mu m) and, for this reason, the decorative coating processes were carried out at room temperature. Temperature increase has a positive effect on thickness of decorative gold coatings obtained from electrolyte based on mercaptotriazole, but this effect is very small, so the heating of electrolyte is not recommended for this type of electrolyte (at 20 degrees C b = 0.08 mu m, at 40 degrees C b = 0.12 mu m and at 60 degrees C b = 0.13 mu m). The best coating roughness profiles are obtained at a temperature of 20 degrees C for both types of electrolyte. The morphology of gold deposits, obtained from both electrolytes, was studied using scanning electron microscopy.

AB  - Recovery of gold and other valuable metals from electronic scrap involves a complex metallurgical flow sheet and requires state-of-the-art recovery technologies that are available in large-scale, integrated smelter and refinery operations. At the end of their use, electronic and other electrical product scrap offer an important recycling potential for the secondary supply of gold and silver into the market. With gold concentrations reaching 200-250 g/t for computer circuit boards, this scrap is an 'urban mine' that is significantly richer in gold than the sources of the primary ores today. This paper gives methods of gold and silver recovery from printed circular board. The methods of purification are given and they separate gold from the impurities (tin, copper and nickel). The obtained gold and silver have 99.99% quality.
