Abstract
<p>Método para extraer litio de un material que contiene litio. Por ejemplo, el método puede comprender lixiviar un material tostado que contiene litio bajo condiciones adecuadas para obtener una composición acuosa que comprende un compuesto de litio como sulfato de litio y/o bisulfato de litio. La composición acuosa que comprende sulfato de litio y/o bisulfato de litio puede ser usada opcionalmente, por ejemplo, en un método para preparar hidróxido de litio que comprende un proceso de electromembrana. El material tostado que contiene litio puede ser preparado, por ejemplo por un método el cual usa una composición acuosa que comprende opcionalmente sulfato de litio y/o bisulfato de litio el cual puede ser obtenido de un método para preparar hidróxido de litio que comprende un proceso de electromembrana como un proceso de electrólisis monopolar o bipolar de dos compartimientos.</p>
