LCA of metal recovery from waste incineration bottom ash
The important role gained by waste incineration in European waste management systems is recently clashing with increasing concerns about loss of resources in waste, i.e. metals. Even though the recovery of valuable resources in residues from waste incineration is becoming a widespread practice, a significant portions of valuables resources remains in the ash and ends up in disposal sites. The g...
متن کاملElectrolytic recovery of silver from low concentrated silver cyanide spent plating solutions
Cyanide silver solution containing 200 to 1000 mg L silver ions were used for recovery studies. The nature of the silver deposit was studied using a Hull cell, and the current density range was selected for electrolysis to recover silver. A batch electrochemical reactor, consisting of a planar stainless steel cathode and platinum anode was used and silver was recovered at 0?04 to 0?2 A dm. The ...
متن کاملApplication of Pulse Plating - Amorphous Alloys
Amorphous alloys can be electrodeposited by direct or pulsed current. According to electrocrystallization theory, a high crystallization overpotential produces microcrystalline structure in the deposits. Thus if the amorphous phase consists of microcrystals, pulsed current is preferable for preparing amorphous alloys. However, another newly proposed theory holds that the amorphous phase structu...
متن کاملHydrometallurgical Recovery of Metals from Large Printed Circuit Board Pieces
The recovery of precious metals from waste printed circuit boards (PCBs) is an effective recycling process. This paper presents a promising hydrometallurgical process to recover precious metals from waste PCBs. To simplify the metal leaching process, large pieces of PCBs were used instead of a pulverized sample. The chemical coating present on the PCBs was removed by sodium hydroxide (NaOH) tre...
متن کاملHydrometallurgical Recovery of Nano-Palladium from Spent Catalyst
Hydrometallurgical recovery of nano-palladium (Pd) from spent Pd/Al2O3 catalyst has been investigated. The Pd content in the spent catalyst sample was assayed to be 0.42% while the remainder was mainly aluminum oxide. Mixture of HCl and AlCl3 was studied as leaching agent for the sample. The Pd was deposited with formic acid. Different parameters affecting leaching and deposition processes such...
