Document Type and Number:
WIPO Patent Application WO/2014/098357
Kind Code:
A1
Abstract:
The present invention relates to a method for extracting lithium from a solution containing lithium, and more particularly, to a method for extracting lithium from a solution containing lithium, comprising the steps of: preparing a solution containing lithium including carbonate ions; obtaining a first precipitate by concentrating the solution containing lithium in order to allow the lithium concentration to be 2.481 g/L or less; performing solid-liquid separation of the concentrated solution containing lithium and the first precipitate; precipitating dissolved lithium as lithium phosphate by inputting a phosphor supplying material into the concentrated solution containing lithium; obtaining a second precipitate by re-concentrating a filtrate with the precipitated lithium phosphate in order to allow the lithium concentration to be 2.481 g/L or less; performing solid-liquid separation of the re-concentrated filtrate and the second precipitate; and precipitating the dissolved lithium as lithium phosphate by inputting nuclear particles into the re-concentrated filtrate.
