Abstract
Un procedimiento para fundir un mineral de sulfuro de cobre con alto contenido de arsénico. En el presente documento se proporciona un procedimiento para fundir un concentrado de sulfuro de cobre con alto contenido de arsénico, que comprende las etapas de: mezclar el concentrado de sulfuro de cobre con alto contenido de arsénico con arena de cuarzo y un material que contiene CaO para obtener un material mezclado; mezclar el material mezclado con un gas reactivo que contiene oxígeno y calentar para su reacción para obtener mata, escoria y gases de combustión que contienen SO2. Mediante la adición de CaO y SiO2 en el procedimiento de fundición, el material de concentrado, el CaO y el SiO2 se dejan reaccionar en el horno a alta temperatura. Los sulfuros de arsénico en el concentrado se oxidan en primer lugar y, entonces, reaccionan químicamente con el CaO del flujo de escorificación para introducirse en la fase de escoria en forma de compuestos basados en calcio de arseniatos de hierro, arsénico, etc., reduciendo de esta manera el contenido de arsénico en la mata de cobre.
