摘要
系统分析了研磨过程中影响石墨片上煤矸石矿物破坏的形态特征(球度、圆度和表面粗糙度)。结合 MS 和 SEM,球度分析表明,石墨呈片状,与黝帘石相似,但与粒状石英和白云石不同;四种矿物的圆度从高到低依次为石墨、石英、白云石和黝帘石。原子力显微镜分析表明,与石英和白云石相比,石墨和黝帘石的表面粗糙度非常低(高于石英)。在研磨过程中,石墨薄片的尺寸和晶体完整性都受到了甘石的破坏,石英和白云石的破坏程度比云母石严重。球度是影响破坏的主要因素:球度越大,破坏越严重,这也与圆度呈负相关,但与表面粗糙度呈正相关。
Innovative correlation relating the destruction of graphite flakes to the morphology characteristics of minerals
The morphology characteristics (sphericity, roundness, and surface roughness) affecting the destruction of gangue minerals on graphite flakes during the grinding process were systematically analyzed. Coupled with MS and SEM, sphericity analysis showed that graphite was flaky, which was similar to muscovite but different from granulous quartz and albite, and the roundness of the four minerals from high to low was graphite, quartz, albite, and muscovite. AFM analysis showed that the surface roughness of graphite and muscovite was very low compared to that of quartz and albite (higher than quartz). The size and crystal integrity of graphite flakes were both destroyed by gangues during the grinding process, and the destruction of quartz and albite was serious compared to that of muscovite. Sphericity dominantly affected the destruction: the larger the sphericity, the more serious the destruction, which was also negatively related to roundness but positively related to surface roughness.
