Study on Recovery of Metals from Printed Circuit Board Using a Gas-Liquid Fluidized Bed

Article Preview

Abstract:

Comminuting and enrichment are the key technology to recycle waste printed circuit boards (WPCBs), in this paper the mechanical separation of WPCBs, comminuting by bang comminute and enrichment by air-solid fluidized bed, was studied. Experiments were designed to examine the impact of the airflow velocity and particle diameter to the air separation process, in order to optimize the operation condition. The results illustrated that it is feasible and very effective to apply gas-solid fluidized bed to recycle WPCBs.
