Abstract

This study investigates geochemical and mineralogical property of kaolin in Isan Ekiti state, using X-Ray fluorescence and X-Ray diffractometer. The X – Ray Fluorescence of Samples is the major indicator, shows that the percentage Silicon oxide (SiO2) for both samples ranges from 50.35% to 49.76% with an average of 50.055%, Aluminum oxide (Al2O3) ranges from 24.02% to 27.25% with an average of 25.6%, Ferric Oxide (Fe2O3) ranges from 3.42% to 5.14%, with an average of 4.28%, Magnesium Oxide (MgO) ranges from 4.54% to 4.24% with an average of 4.38%, Calcium oxide from 0.67% to 0.63% with an average of 0.65%, and Potassium Oxide range from 3.97 to 2.47, with an average of 3.22%. The Results of X – Ray diffractometer for samples shows that Quartz has its peak at (34.65, 2.70, 2.01 and 2.75) 2Ө values for a sample while a sample was also identified at (32.57, 3.81, 2.23 and 1.65) 2Ө values. Kaolinite has its peak at (8.82, 4.13, 4.01, 2.84, 4.22, 4.52and 1.43) 2Ө values for a sample while another sample was also identified at (8.78,4.61, 4.42, 3.63, 6.29, 4.84 and 1.52) 2Ө values. The Anatase also has its at (4.76 and 2.32) 2Ө values for a sample while a sample was also identified at (3.64 and 3.75) 2Ө values. The Kaolinite in the samples ranges from 29.97% to 34.09% with an average of 32.03%, when compared with standard parameter, its suitable and can be used in coated paper, and when properly beneficiated, will be applicable in grades of ceramic production.

尼日利亚 Isan Ekiti 地区高岭土的地球化学、矿物学特性和工业适用性

本研究使用 X 射线荧光和 X 射线衍射仪对伊桑-埃基蒂州高岭土的地球化学和矿物学性质进行了调查。样品的主要指标 X 射线荧光显示，两种样品中氧化硅（SiO2）的百分比从 50.35% 到 49.76%不等，平均为 50.055%；氧化铝（Al2O3）的百分比从 24.02% 到 27.25%不等，平均为 25.6%；氧化铁（Fe2O3）的百分比从 24.02% 到 27.25%不等，平均为 25.6%。氧化铁（Fe2O3）从 3.42% 到 5.14%，平均为 4.28%；氧化镁（MgO）从 4.54% 到 4.24%，平均为 4.38%；氧化钙从 0.67% 到 0.63%，平均为 0.65%；氧化钾从 3.97% 到 2.47%，平均为 3.22%。样品的 X 射线衍射仪结果显示，石英在一个样品中的峰值为（34.65、2.70、2.01 和 2.75）2Ө，而另一个样品的峰值为（32.57、3.81、2.23 和 1.65）2Ө。一个样品的高岭石峰值为 (8.82, 4.13, 4.01, 2.84, 4.22, 4.52 和 1.43) 2Ө，另一个样品的峰值为 (8.78,4.61, 4.42, 3.63, 6.29, 4.84 和 1.52) 2Ө。一个样品中的铝黄铁矿的 2Ө 值为（4.76 和 2.32），另一个样品中的铝黄铁矿的 2Ө 值为（3.64 和 3.75）。样品中的高岭石含量在 29.97% 到 34.09% 之间，平均值为 32.03%，与标准参数相比，高岭石适用于铜版纸，经适当选矿后可用于陶瓷生产。
