摘要: 通过光学显微镜、X射线衍射（XRD）、X射线荧光光谱（XRF）、电子探针和扫描电镜（SEM）等手段，对广东某高岭土进行了系统研究。研究表明，该高岭土淘洗率为71%。石英和钾长石在+0.045 mm粒级中富集；白云母在+0.030 mm粒级富集；高岭石（埃洛石）在-0.045 mm粒级中富集。各粒级烧成白度较高，-0.010+0.005 mm粒级烧成白度最高，达到85.69%。目的矿物高岭石为片状和叠片状，埃洛石为管状。高岭土中Ti含量较低，为0.051%，Fe含量较高，为1.009%，主要以表面铁和晶格铁形式存在。Abstract: This paper made systematic studies on kaolin by means of optical microscope, X-ray diffraction (XRD), X-ray fluorescence spectrum(XRF), electron probe and scanning electron microscope (SEM). Results show that the elutriation rate of kaolin is 71%.Quartz and potash feldspar were enriched as -0.045mm size; Muscovite and kaolinite (halloysite) were enriched as +0.030 mm and -0.045mm size, respectively.After calcinations, the whiteness of each particle size is high, especially in -0.010+0.005mm, with the whiteness reached to 85.69%. Kaolinite, the objective mineral, shows patchy and overlapping shape. Halloysiteshows tubular form. The titanium content of kaolin is 0.051%. However, itsiron content is higher,which reaches 1.009% and mainly exists as the forms of surface iron and lattice iron.
