Abstract

Sistemas y metodos que usan evaporacion solar para preconcentrar salmueras que contienen litio a o cerca de una saturacion de litio, seguida por procesos de separacion para separar el litio de las impurezas. Una corriente de impureza separada se recicla a un punto en la secuencia de evaporacion donde las condiciones son favorables para su precipitacion y remocion o se coloca en un estanque de evaporacion separado o se reinyecta bajo tierra, en tanto que una corriente de impureza inferior se transfiere a una o mas de la ubicacion de remocion, a un estanque posterior en la secuencia, o a una planta de litio o instalacion de concentracion. Entonces puede tener lugar una concentracion adicional de litio por evaporacion debido a que se remueven las impurezas, eliminando de este modo las perdidas de litio debido a la coprecipitacion y logrando concentraciones significativamente mayores de litio.
