Abstract

Sulphide ore is one of the most abundant minerals in nature. Indonesia has a very diverse potential for minerals, ranging from iron ore, laterite iron ore, iron sand to iron sulphide ore. Sulphide ore is one of the minerals that has the potential to become the parent mineral for gold. One area that has sulfide ore is Wanggameti Village, Matawai Lapawu District, East Sumba Regency. This condition encourages research to be carried out with the aim of knowing the types of minerals in sulfide ores by XRD analysis and to identify the content of elements in sulfide ores by XRF analysis. The results showed that the results of XRD analysis of sulfide ore samples taken from Wanggameti Village, Matawai Lapawu District, East Sumba Regency contained minerals of the types Quartz (SiO2), Calsite (CaCO3), Corundum (Al2O3), Iron Aluminum Silicon (Fe3Al2Si3) and Muscovite 2M1 ( KAl2Si3AlO10(OH)2). And the results of the analysis of the content of elements in the sulfide ore with XRF is 36.6% Si; S 1.2%; K 5.0%; Ca 27.8%; Ti 1.98%; V 0.23%; Cr 0.09%; Mn 0.77%; Fe 19.3%; Ni 2.99%; Cu 0.43%; Zn 0.1%; Mo 2.8%; Ba 0.2%; Eu 0.2% and Re 0.3%. Keywords:sulfide ore, mineral type and chemical composition

东松巴县马塔外拉帕乌区王格梅蒂村硫化物矿石特征及化学成分

硫化物矿是自然界中储量最丰富的矿物之一。印度尼西亚的矿产潜力非常多样化，从铁矿石、红土铁矿石、铁砂到硫化铁矿石。硫化铁矿石是有可能成为黄金母矿的矿物之一。一个有硫化物矿的地区是东松巴县Matawai Lapawu区的Wanggameti村。这种情况鼓励开展研究，目的是通过XRD分析了解硫化矿石中的矿物类型，并通过XRF分析确定硫化矿石中的元素含量。结果表明:在东松巴县Matawai Lapawu区Wanggameti村采集的硫化矿样品XRD分析结果中，矿物类型为石英(SiO2)、方解石(CaCO3)、刚玉(Al2O3)、铁铝硅(Fe3Al2Si3)和白云母2M1 (KAl2Si3AlO10(OH)2)。XRF分析结果表明，该硫化矿石中Si含量为36.6%;年代的1.2%;K 5.0%;Ca 27.8%;Ti 1.98%;V 0.23%;Cr 0.09%;Mn 0.77%;铁19.3%;倪2.99%;铜0.43%;锌0.1%;密苏里州的2.8%;英航0.2%;欧盟0.2%，巴西0.3%。关键词:硫化矿，矿物类型，化学成分
