Hydrochemical analysis of surface water flow from an abandoned iron ore mine
| Deskripsi | The purpose of this research is to investigate the potential formation of contaminants in abandoned mining areas due to the interaction between rocks, water, and air, as well as their impact on surface water quality around the mine area.Methods. Mineralogical analysis using an optical microscope and X-ray diffraction (XRD) on iron ore samples obtained from the stockpiles and chemical analysis of water obtained from the mining site and downstream river.Findings. Iron ore at the study site is dominated by iron oxide minerals such as magnetite, hematite, and goethite. Additionally, quartz, birnessite, pyrite, and chalcopyrite minerals were also found. The mineral content indicates the presence of two sulfide minerals that have the potential to form acid mine drainage, namely; pyrite (FeS2) and chalcopyrite (CuFeS2). The pH measurement results of the water flowing from the iron ore stockpile have a pH of 2.9, while the void and surrounding river vary from 6.4 to 8.2. |
