煤氣化灰渣差異性分析及浮選加工優化研究摘要

為了更好地探究煤氣化灰渣的成分特征以及分析不同物化特性帶來的浮選效率差異，本文從煤氣化灰渣的結構特征、化學成分、物理性質入手，分析了不同性質煤氣化灰渣的差異性，并在此基礎上進行浮選加工優化研究。通過粒度分布、表面電荷等多種浮選工藝參數的調整，對煤氣化灰渣進行浮選加工實驗研究，并對其效果進行評估與分析。通過煤氣化灰渣樣品的XRF、XRD、TG-DTA等多種手段對其成分結構進行分析，探究其浮選加工效果的影響因素，并提出優化方案。研究結果表明，對于不同成分特征煤氣化灰渣的浮選加工處理需要針對其不同的物化特性進行調整與優化，優化后可以明顯提高灰渣的金屬回收率與質量，具有一定的工程應用前景。
