Novel fluxing strategy of copper matte smelting and trace metals in E-Waste recycling

The distribution behavior of trace metals between copper matte and spinel-saturated iron silicate slags was investigated at 1250 °C pSO2 0.25 atm low silica concentrations. experiments were conducted in magnetite (Fe3O4) spinel crucibles controlled CO-CO2-SO2-Ar gas mixtures using a high-temperature equilibration-quenching technique. concentrations elements matte, spinel, slag quantified by electron probe X-ray microanalysis laser ablation-inductively coupled plasma-mass spectrometry. (Ag, Ni, Co, Sn) all phases their coefficients calculated as function grade. Results show that silver nickel can be effectively recovered into whereas cobalt tin are predominantly deported phases, respectively. These results augment the fundamental thermodynamic data metal distributions smelting processes low-silica fluxing practices.
