Abstract

<p>LA PRESENTE INVENCIÓN SE REFIERE A UN MÉTODO PARA CONTROLAR LA FORMACIÓN DE ESPUMA DURANTE LA LIXIVIACIÓN ATMOSFÉRICA O SUSTANCIALMENTE ATMOSFÉRICA DE UN SULFURO DE METAL. EN ALGUNAS MODALIDADES, EL MÉTODO PUEDE COMPRENDER LAS ETAPAS DE (A) PRODUCIR UN CONCENTRADO DE SULFURO DE METAL MEDIANTE FLOTACIÓN; (B) PRODUCIR UNA CORRIENTE DE COLAS MEDIANTE FLOTACIÓN; Y, (C) DESVIAR UNA PORCIÓN O TODA DE TAL CORRIENTE DE COLAS PRODUCIDAS A UN CIRCUITO DE LIXIVIACIÓN ATMOSFÉRICA O SUSTANCIALMENTE ATMOSFÉRICA DE SULFURO. UN DIAGRAMA DE FLUJO DE RECUPERACIÓN DE METAL TAMBIÉN SE DESCRIBE. EN ALGUNAS MODALIDADES, EL DIAGRAMA DE FLUJO DE RECUPERACIÓN DE METAL PUEDE COMPRENDER UNA OPERACIÓN UNITARIA QUE COMPRENDE: (A) UN CONCENTRADOR DE SULFURO QUE COMPRENDE UN CIRCUITO DE FLOTACIÓN, EL CIRCUITO DE FLOTACIÓN PRODUCE UN CORRIENTE DE CONCENTRADO DE SULFURO DE METAL, Y UNA CORRIENTE DE COLAS; Y, (B) UN CIRCUITO DE LIXIVIACIÓN ATMOSFÉRICA O SUSTANCIALMENTE ATMOSFÉRICA DE SULFURO DE METAL. EL CONCENTRADOR DE SULFURO PUEDE SER OPERATIVAMENTE CONECTADO AL CIRCUITO DE LIXIVIACIÓN ATMOSFÉRICA O SUSTANCIALMENTE ATMOSFÉRICA DE SULFURO DE METAL MEDIANTE AMBAS DE TAL CORRIENTE DE CONCENTRADO DE SULFURO DE METAL, Y TAL CORRIENTE DE COLAS.</p>
