Extraction of zinc from blast furnace dust in ammonia leaching system
In this research, the extraction of zinc from the blast furnace dust in the ammonia leaching system containing different leaching agents (NH3, (NH4)3AC, (NH4)2CO3, (NH4)2SO4, NH4Cl) was investigated. Meanwhile, the effects of different total ammonia concentrations, ammonia/ammonium ratios, solid-liq...

| description | In this research, the extraction of zinc from the blast furnace dust in the ammonia leaching system containing different leaching agents (NH3, (NH4)3AC, (NH4)2CO3, (NH4)2SO4, NH4Cl) was investigated. Meanwhile, the effects of different total ammonia concentrations, ammonia/ammonium ratios, solid-liquid ratios, stirring speeds, and leaching temperatures on the extraction of zinc were studied. The results showed that ammonium sulfate was particularly effective and the extraction efficiency of zinc is up to 86.48% under the following conditions: total ammonia concentration of 5.0 mol/l, ammonia/ammonium ratio of 1:1, solid-liquid ratio of 1:5, temperature of 45°C, leaching time of 60 min, and stirring speed of 350 rpm. |
