Abstract

Language:

The distributions of precious metals (gold, silver, platinum, and palladium) between copper matte and silica-saturated FeOx-SiO2/FeOx-SiO2-Al2O3/FeOx-SiO2-Al2O3-CaO slags were investigated at 1300 °C and PSO2 = 0.5 atm. The experiments were performed in silica crucibles under a flowing CO-CO2-SO2-Ar gas atmosphere. The concentrations of precious metals in matte and slag were analyzed using Electron Probe X-ray Microanalysis and Laser Ablation-High-Resolution Inductively Coupled Plasma-Mass Spectrometry, respectively. The results displayed the precious metal concentrations in both matte and slag, as well as the distribution coefficients of these metals between the two phases, as a function of matte grade. The findings contribute to a better understanding of the separation and recovery of precious metals during the WEEE reprocessing process.
