Abstract

La descripción se refiere a métodos para preparar hidróxido de litio. Por ejemplo, tales métodos pueden Comprender mezclar un material que contiene litio con una composición acuosa acídica que comprende opcionalmente sulfato de litio y obtener de ese modo una mezcla; tostar la mezcla en condiciones adecuadas para obtener materiales tostados que contienen litio; lixiviar el material tostado en condiciones adecuadas para obtener una primera composición acuosa que comprende sulfato de litio para un proceso de electromembrana en condiciones adecuadas para la conversión al menos parcial del sulfato de litio en hidróxido de litio y para obtener una segunda composición acuosa que comprende sulfato de litio, el proceso de electromembrana que involucra un ánodo despolarizado de hidrógeno; aumentar opcionalmente la concentración de ácido en la segunda composición acuosa; y usar la segunda composición acuosa que comprende sulfato de litio como la composición acuosa acídica que comprende opcionalmente sulfato de litio para mezclar con el material que contiene litio y para obtenerla mezcla.
