Au and Ag distribution in alloys produced from the smelting of printed circuit boards - an assessment using SEM-EDS, EPMA, and LA-ICP-MS analysis
2020
Journal of the Southern African Institute of Mining and Metallurgy
Synopsis Electronic waste such as printed circuit boards (PCBs) often contains important concentrations of precious metals such as Au and Ag, which are typically recovered using pyrometallurgical methods as a first step. Understanding the phase chemistry and distribution of precious metals in alloys is of value to the pyrometallurgist, as this gives information on phase partitioning in the furnace. In the present study we aimed at determining the contributions of different phases to the Au and
