Hydrothermal Production of Highly Pure Nano Pyrite in a Stirred Reactor

Abstract

<em>In this study, pyrite was produced by hydrothermal precipitation from the reaction between FeSO₄ and Na₂S₂O₃ at high pressure and high temperature in a stirred reactor. The solid product was purified by means of solvent extraction to remove sulfur. Powder was characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and thermal analyses. Results indicated that pyrite was produced as nanostructure with high purity.</em>
