Abstract
Characterization and identification of Maitara Island clay have been carried out. This study aims to determine the types of minerals contained in the Maitara Island clay. The analytical methods used include X-Ray Fluorescence (XRF) to determine the chemical composition of Maitara Island clay, X-Ray Diffraction (XRD) for mineralogical analysis of Maitara Island clay, Fourier Transmission Infra Red (FTIR) to determine the types of vibrations that exist between the atoms in clay minerals from Maitara Island, and Scanning Electron Microscopy (SEM) to determine the morphology of clay minerals. XRF analysis showed that silica was the element found to dominate the clay minerals with a percentage of 40.79%. Moreover, the highest oxide component found was SiO2 with a percentage of 87.25%. XRD analysis indicated that the Maitara Island clay minerals are composed of montmorillonite, magmatite, aluminum oxide colondrum, cristobalite, lime, titanium oxide, and hematite. The results of FTIR analysis denoted the presence of silica as silanol and siloxane. SEM images showed angular grains which signified silica as the main component in the clay minerals of Maitara Island
Highlights
Indonesia has abundant natural mineral resources ranging enclosed within its grounds such as clay
In addition to Bacan Island, an area ought to be explored for its clay minerals is the Maitara Island
x-ray fluorescence (XRF) and x-ray diffraction (XRD) analyses were carried out by placing clay powder sample on a sample holder, whereby the sample would be exposed to x-rays beam on its surface
Summary
Indonesia has abundant natural mineral resources ranging enclosed within its grounds such as clay. One of its areas that contains abundant mineral content is North Maluku province. The North Maluku Province possesses tremendous potential in producing minerals such as gold, copper, manganese, iron, iron sand, coal, nickel ore, natural gas, limestone and marble [1,2,3,4]. Within the province the largest geological resource content was found on Bacan Island at around 70 million tons. It holds minerals such as manganese, chromite, limestone, calcite, bentonite, diatomaceous, talc, kaolin, pearlite, magnesite, andesite, sandstone, pumice, diorite, and other various precious rocks [5]. In addition to Bacan Island, an area ought to be explored for its clay minerals is the Maitara Island
