The current study presents an effort to develop a sustainable hydrometallurgical process for the recovery of copper from waste printed circuit boards (PCBs) be applied at local small medium industrial units. aims separate and recover filter dust produced during crushing PCBs using hammer mill in recycling facility. Due high plastic content (approximately 30% w/w), metal fraction was separated g...

Abstract Brass melting slag is a valuable secondary resource for the recovery of copper and zinc. The hydrometallurgical process this material challenge, because its limited dissolution in sulfuric acid. present study aimed at studying combined pyro-hydrometallurgical treatment processes involving high temperature oxidation acid leaching to industrial brass recover effect on performance efficie...

Thin films of tin (II) sulfide (SnS) were deposited onto a 500 µm thick copper substrate by chemical bath method. The effect sodium (Na) doping in these was studied. synthesis the performed at temperatures 60, 70, and 80 °C for 5 min. microstructure SnS analyzed scanning electron microscopy (SEM) showed compact morphology °C. edges grains rounded off with addition commercial surfactant. thickne...

Electronic waste (e-waste) is an emerging health and environmental burden due to the toxic substances present within e-wastes. To address this burden, e-wastes contain various base, rare earth noble metals, which can be recovered from these substances, thus serving as secondary sources of metals. Pyrometallurgical hydrometallurgical processes have been developed extract metals e-waste. However,...

Laboratory studies have been carried out on the processing of gold-bearing concentrate from “Jamgyr” deposit using JIN CHAN reagent. The influence concentration CHAN, duration leaching, temperature solution were studied. As a result research, extraction gold and silver into cyanide-free technology was 97,5% 96%, respectively. obtained solutions by method sorption MA940BG (gold) ion-exchange res...

Hydrometallurgical leaching solutions are often rich in iron, which was traditionally considered a major impurity. However, iron can be selectively separated and recovered by applying appropriate solvent extraction stripping techniques, the resulting valorized for synthesis of high-added-value products, such as magnetic oxide nanoparticles (mIONPs). The aim this study to synthesize high-quality...
