Mecanism and kinetics of pyrite transformation at elevated temperatures

Trabajo de investigación desarrollado por el profesor Óscar Jerez del GEA-UdeC en conjunto con el profesor Álvaro Aracena del Laboratorio de Investigación Aplicada del Área de la Metalurgia Extractiva (LIAM). Publicado en la revista Physicochemical Problems of Minerals Processing

Abstract: Pyrite (FeS2) is known as a sulfide that provides energy for various pyrometallurgical processes (fusion and conversion). There are several studies related to the evaluation of pyrite oxidation mechanisms at high temperatures, obtaining discrepancies in the products generated.
