Presentation Title Recovery of Valuable Metals from Flue Dust of Electronic Waste

On-Site Speaker (Planned) Hyunju Lee
Abstract Scope A flue dust of electronic waste (e-waste) is generated during smelting process from e-waste. However, recovery studies on flue dust from e-waste are not well known because of insufficient information about the components. In this study, the flue dust from e-waste was investigated as the potential metal resource in order to obtain valuable metals including copper, iron, gold, and silver using physical and chemical methods. In the physical process, size separation was performed and then each particle fraction weight and composition were measured. In the chemical process, a two-step process was performed for selective metal recovery. Three different solutions (HNO3, HCl, H2SO4) were used for recovery of base metals as a first leaching and second leaching process was performed for selective precious metals recovery. All experiments were conducted with a variation of time and temperature. The kinetic study was also calculated based on the shrinking core model.
