This study presents an evaluation of arsenic and other trace metals in the Hrazdan Iron-Ore project in Armenia using a methodology typically associated with Geometallurgical characterization. The principal host of the trace elements is pyrite and oxidized equivalents, which are concerning due to their potential to generate acidic pH in contacting water and mobilize metals. In the Hrazdan deposit, a general excess of neutralizing carbonate minerals provides adequate buffering against generated acid, limiting the mobility of metallic cations in solution. However, metalloids forming oxyanion species, such as arsenic and chromium, exhibit increased mobility in neutral to alkaline mine drainage. The geometallurgical assessment of the mine waste allows for the explanation of geochemical testwork results, aiding in the evaluation of potential issues related to mine waste storage and timing of metal release. This research serves as a foundational framework for developing mitigation strategies to address environmental concerns associated with mine waste management.
