Abstract

La presente invención describe un proceso para tratar un residuo de lixiviación generado en una lixiviación de un concentrado de metal que contiene azufre. En este, el residuo de lixiviación es alimentado dentro de un reactor, en donde se inyecta un gas de fluidización dentro del reactor para formar una cama fluidizada que contiene cuando menos una porción del residuo de lixiviación. De este modo, el residuo de lixiviación es calentado en la presencia de partículas inertes a una temperatura de entre 600 y 900 ºC en una atmosfera oxidante para producir partículas calcinadas y SO2. Cuando menos 60% en peso de las partículas inertes son removidas de la cama fluidizada mientras que cuando menos 60% en peso de las partículas calcinadas son removidas junto con un flujo de gas que contiene gases de escape y el gas de fluidización.
