煤气化灰渣差异性分析及浮选加工优化研究

煤气化灰渣差异性分析及浮选加工优化研究摘要

为了更好地探究煤气化灰渣的成分特征以及分析不同物化特性带来的浮选效率差异，本文从煤气化灰渣的结构特征、化学成分、物理性质入手，分析了不同性质煤气化灰渣的差异性，并在此基础上进行浮选加工优化研究。通过粒度分布、表面电荷等多种浮选工艺参数的调整，对煤气化灰渣进行浮选加工实验研究，并对其效果进行评估与分析。通过煤气化灰渣样品的XRF、XRD、TG-DTA等多种手段对其成分结构进行分析，探究其浮选加工效果的影响因素，并提出优化方案。研究结果表明，对于不同成分特征煤气化灰渣的浮选加工处理需要针对其不同的物化特性进行调整与优化，优化后可以明显提高灰渣的金属回收率与质量，具有一定的工程应用前景。
