Abstract

Un método para la fabricación de cloruro de litio y un método para la fabricación de carbonato de litio. El método para la fabricación de una solución acuosa de cloruro de litio incluye mezclar uniformemente una sal de fosfato que contiene litio con cloruro de calcio para preparar una mezcla, calentar la mezcla a una temperatura elevada de más de o igual a 450ºC para preparar un producto que incluye cloroapatita y cloruro de litio mezclados, añadir agua al producto para obtener una suspensión que incluye una mezcla de cloroapatita escasamente soluble (CAp) y cloruro de litio hidrosoluble, y separar sólido-líquido la suspensión para obtener cloroapatita y una solución acuosa de cloruro de litio. La presente también proporciona un método para la fabricación de carbonato de litio mediante la adición de carbonato de sodio a la solución acuosa de cloruro de litio. En el método para la fabricación de carbonato de litio de la presente, la concentración de iones de litio en la solución acuosa es mayor de o igual a 10.000 ppm.A method for the manufacture of lithium chloride and a method for the manufacture of lithium carbonate. The method for manufacturing an aqueous solution of lithium chloride includes uniformly mixing a phosphate salt containing lithium with calcium chloride to prepare a mixture, heating the mixture at an elevated temperature of more than or equal to 450 ° C to prepare a product which includes mixed chloropatite and lithium chloride, add water to the product to obtain a suspension that includes a mixture of sparingly soluble chloropatite (CAp) and water-soluble lithium chloride, and separate the solid-liquid suspension to obtain chloropatite and an aqueous chloride solution lithium The present also provides a method for the manufacture of lithium carbonate by adding sodium carbonate to the aqueous lithium chloride solution. In the method for manufacturing lithium carbonate herein, the concentration of lithium ions in the aqueous solution is greater than or equal to 10,000 ppm.
