Abstract

One of the naturally abundant minerals with diverse industrial applications is the clay mineral. The choice of application depends on the characteristics of the clay. In this study, internal composition of the large and untapped Ogwuta clay deposit located in Afikpo, South Eastern Nigeria was further investigated as a guide to its applications. Scanning Electron Microscope (SEM), Thermogravimetric (TG), and X-ray diffraction (XRD) techniques were employed to access its composition. The scanning electron micrograph revealed that the clumping of the clay particles was due to edge-to-edge, edge-to-face or face-to-face flocculation. Thermogravimetric analysis revealed that at temperature range of 153-325°C, the observed weight percent loss (13.67%), consistent with kaolinitic clays, was due to the removal of water of crystallization of the interlayer cations. X-ray diffraction result further revealed kaolinite as the predominant mineral with the presence of quartz and polygorskite. This study has revealed the applicability of Ogwuta source clay in both industrial and manufacturing activities.

利用先进的分析工具表征Ogwuta源粘土

粘土矿物是一种天然丰富的矿物，具有多种工业用途。应用的选择取决于粘土的特性。在这项研究中，进一步调查了位于尼日利亚东南部Afikpo的大型未开发Ogwuta粘土矿床的内部组成，以指导其应用。采用扫描电镜(SEM)、热重(TG)和x射线衍射(XRD)等技术对其组成进行了表征。扫描电镜显示，粘土颗粒的结块是由于边对边、边对面或面对面的絮凝作用。热重分析表明，在153 ~ 325℃的温度范围内，由于层间阳离子的结晶水的去除，高岭石粘土的失重率为13.67%，与高岭石粘土一致。x射线衍射结果进一步揭示了高岭石为主要矿物，石英和多菱长石的存在。本研究揭示了小武太源粘土在工业和制造业活动中的适用性。
