Journal ArticleDOI
The effects of Na2O/SiO2 molar ratio, curing temperature and age on compressive strength, morphology and microstructure of alkali-activated fly ash-based geopolymers
Alexandre Silva de Vargas,Denise Carpena Coitinho Dal Molin,Antonio Cezar Faria Vilela,Felipe José da Silva,Bruno Pavão,Hugo Marcelo Veit +5 more
TL;DR: In this paper, an analysis of fly ash paste morphology was performed using scanning electron microscopy (SEM/EDS) and microstructural properties with X-ray Diffraction (XRD) analysis.
Journal ArticleDOI
Recovery of copper from printed circuit boards scraps by mechanical processing and electrometallurgy.
Hugo Marcelo Veit,Andréa Moura Bernardes,Jane Zoppas Ferreira,Jorge Alberto Soares Tenório,Célia de Fraga Malfatti,Célia de Fraga Malfatti +5 more
TL;DR: The results demonstrate the technical viability of recovering copper using mechanical processing followed by an electrometallurgical technique and the copper obtained by electrowinning is above 98% in most of the tests.
Journal ArticleDOI
Utilization of magnetic and electrostatic separation in the recycling of printed circuit boards scrap
Hugo Marcelo Veit,T.R. Diehl,Anderson Paulo Salami,J.S. Rodrigues,Andréa Moura Bernardes,Jorge Alberto Soares Tenório +5 more
TL;DR: Printed circuit boards, which are used in personal computers, were studied in order to recover the metals in the circuit boards through mechanical processing, such as crushing, screening, as well as magnetic and electrostatic separation, to demonstrate the feasibility of using these processes to separate metal fractions from polymers and ceramics.
Journal ArticleDOI
Printed wiring boards for mobile phones: characterization and recycling of copper.
Angela Cristina Kasper,Guilherme B. Berselli,Bruno Dias Freitas,Jorge Alberto Soares Tenório,Andréa Moura Bernardes,Hugo Marcelo Veit +5 more
TL;DR: The printed wiring boards scrap of mobile phones were characterized in order to recycle some of the device components, using techniques of mechanical processing, hydrometallurgy and electrometallurgical to demonstrate the technical feasibility of recovery of copper.
Journal ArticleDOI
Evaluation of gold and silver leaching from printed circuit board of cellphones.
TL;DR: The results show that the digestion with aqua regia was efficient to characterize the metals present in the PCBs of mobile phones, and the best method to solubilize silver was by digesting the sample with nitric acid.
