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%.
