英文摘要 | Phosphogypsum is the byproduct discharged from phosphate industry. A novel process was proposed for converting phosphogypsum into ammonium sulfate via phosphogypsum carbonation with ammonia. The effects of stirring speed, reaction time, initial temperature, CO2 partial pressure, liquid-solid ratio and excess ammonia ratio were evaluated. The main phases presented before and after the carbonation process were identified using X-ray fluorescence (XRF), X-ray diffraction (XRD), scanning electron microscopy with energy dispersive X-ray (SEM-EDX) and carbon-sulfur (CS) analytical techniques. The phosphogypsum was found to have the highest carbonation conversion of approximately 97% in 5 min. The product collected from the reaction was characterized as calcite with the average particle size smaller than the raw phosphogypsum. (C) 2014 Elsevier Ltd. All rights reserved. |
