Lithium-forward osmosis concentration step of the solution containing the salt are disclosed. Lithium-osmotic pressure difference between the contained salt solution and than the second salt solution having a high osmotic pressure, the semi-permeable forward osmosis membrane than the lithium of low osmotic pressure through - a drive force for passing the water with a salt solution of higher osmotic pressure from the contained salt solution It is used. In addition, the reverse osmosis process technology and forward osmosis process technology is used at the same time, the lithium-containing salt is to concentrate the solution, and the recovery of water that can be recycled to the process, a two-part operation is described. Forward osmosis process, the forward osmosis use of (i) at atmospheric pressure exceeds the pressure to help cause the flow of water through the membrane or (ii) the use of sub-atmospheric pressure, or (iii) the use of all of the pressure, or (iv) one or more additives It does not require the use is carried out.
