Abstract

Un método para la recuperación de vanadio de una corriente de alimentación que contiene vanadio, comprendiendo el método: someter la corriente de alimentación que contiene vanadio a una etapa de lixiviación ácida para formar un lodo que incluye una solución de lixiviación cargada que comprende vanadio disuelto y un residuo sólido; pasar el producto de la etapa de lixiviación a una etapa de separación de sólidos/líquidos para producir una solución de lixiviación cargada que comprende vanadio disuelto; poner en contacto la solución de lixiviación cargada con un agente reductor para reducir una o más especies en la solución de lixiviación cargada; pasar la solución de lixiviación cargada a una etapa de precipitación en la que se aumenta el pH de la solución para precipitar un producto de vanadio; y recuperar el producto de vanadio de la solución.A method for the recovery of vanadium from a vanadium-containing feed stream, the method comprising: subjecting the vanadium-containing feed stream to an acid leaching step to form a slurry that includes a loaded leach solution comprising dissolved vanadium and a solid residue; passing the product from the leach step to a solid/liquid separation step to produce a charged leach solution comprising dissolved vanadium; contacting the loaded leach solution with a reducing agent to reduce one or more species in the loaded leach solution; passing the charged leach solution to a precipitation step in which the pH of the solution is increased to precipitate a vanadium product; and recovering the vanadium product from the solution.
