2016-11-1 Gold was recovered from waste electrical and electronic equipment (WEEE) by a novel methodology of substrate optimized oxidation with commercial grade ammonium persulfate ((NH 4) 2 S 2 O 8). The parameters that determined the substrate oxidation were studied through 2 3 full factorial experimental design. A methodology to recover gold from WEEE using ammonium persulfate is proposed. • Au recovery is investigated implementing response surface methodology. • Optimized quantities of ammonium persulfate were used to extract non leaching gold. • This methodology reduced reaction time and contaminant by A novel methodology, using ammonium persulfate ( (NH 4 ) 2 S 2 O 8 ), to recover gold from waste E-waste has been assayed. The findings presented by Alzate et al. (2016) This paper presents a novel methodology to recover gold from waste electrical and electronic equipment (WEEE) using ammonium persulfate ( (NH 4) 2 S 2 O 8 ). Gold was recovered as a fine coating using substrate oxidation without shredding or grinding process. This paper presents a systematic approach on gold recovery from electronic waste (e-waste) using ammonium persulfate. This process was developed as a response to the lack of hydrometallurgical systems capable of separating gold from its metallic substrate without material grinding, with minimum formation of pollutants, and achieving a lower reaction time. ammonium persulphate in gold recovery– Grinding Mill China.

AmmoniumPersulfateAPSJTT Chemical Sales ~ an interaction with an oxidizing agent such as ammonium persulfate (APS) would improve the adsorption of gold and silver on AC. Increasing the APS concentrations from 0.0 M to 0.01 M drastically improved the gold adsorption efficiency from 5% to 85% after only 10 min. Almost 95% of both metals Increasing the APS concentrations from 0.0 M to 0.01 M drastically improved the gold adsorption efficiency from 5% to 85% after only 10 min. Almost 95% of both metals was adsorbed after 90 min. EDXRF chart confirmed the adsorption of gold and silver on AC.
