Application of mineral processing methods in recycling the waste printed circuit board
(Bor : Mining and Metallurgy Institute, 2022)
Recycling of the waste printed circuit boards (PCBs) is necessary from both an economic and an
environmental point of view. Large amounts of waste contain significant amounts of valuable metals
used as the secondary ...
Cytotoxicity of the gold complex based on mercaptotriazole - A comparison with the conventional cyanide electrolyte
(Journal of the Indian Chemical Society, 2021)
The study presents the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay results on human erythroleukemia K562 cell line to compare the toxicity of electrolytes based on the mercaptotriazole gold ...
CHARACTERIZATION OF THE GOLD MERCAPTOTRIAZOLE COMPLEX USING THE TANDEM QUADRUPOLE MASS SPECTROMETRY (TQD)
(Bor : Mining and Metallurgy Institute, 2022)
This work is aimed to characterize the gold complexes using the electron spray ionization (ESI), and atmospheric solids analysis probe (ASAP), tandem quadrupole mass spectrometer (TQD). It is demonstrated here that the use ...

Electrochemical stability of gold complex based on mercaptotriazole at optimal condition
(Springer Science and Business Media Deutschland GmbH, 2022)
This study investigates the electrochemical stability of the gold complex based on mercaptotriazole at an optimum pH of nine in the electrolyte with a gold concentration of 2.5 g dm−3. The stability of the complex was ...
E-scrap processing: Theory and practice
(De Gruyter, 2021)
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 ...
Production of sub-micro sized silver particles by chemical reduction method in an environmentally-friendly manner
(Savez inženjera metalurgije Srbije, Beograd, 2020)
Silver nitrate in the solution was reduced in the presence of the dispersants by ascorbic acid, and silver particles were generated. The main goal was to examine the influence of different dispersants. The purpose was to ...
Complementary methods for characterization of the corrosion products on the surface of Ag60Cu26Zn14 and Ag58.5Cu31.5Pd10 brazing alloys
(Walter de Gruyter Gmbh, Berlin, 2020)
Corrosion products formed on the surface of two silver brazing alloys after the potentiostatic polarization in 3.5% sodium chloride solution were characterized by the standard methods such as, the X-ray diffraction, ...
Recovery of tungsten trioxide from waste diamond core drilling crowns by nitric acid leaching
(International Journal of Refractory Metals & Hard Materials, 2021)
A cost-effective and simple hydrometallurgy procedure for recycling the diamond core drilling crowns by nitric acid leaching, followed by the sodium hydroxide leaching, has been developed. The effect of temperature, nitric ...
