Abstract:A pilot test was carried out to recover valuable metals from WEEEs in an oxygen-enriched side-blown smelting furnace with total bed area of 3.6 m2. Content of Cu, Au and Ag in slag is 0.11%, 0.20 g/t and 1.00 g/t respectively with recovery rate of Cu, Au and Ag of 98.43%, 97.58% and 99.27%, respectively under the conditions including feed rate of solid of 1.04-2.30 t/h, concentration of oxygen gas in smelting zone of 65.80%-66.11%, and concentration of oxygen gas in fuming zone of 31.96%-36.32%. CaO-SiO2-Al2O3 slag system containing some FeO for smelting process is appropriate under the conditions of CaO/SiO2=0.33-0.41, Fe/SiO2=0.07-0.14, and Al2O3 content of 11.33%-12.77%. The test results demonstrate that WEEEs can be processed effectively by oxygen-enriched side-blown smelting technology.
