    Abstract: Provided are an apparatus and a method for ion-exchange extraction of lithium from natural or technological brine by using a lithium-selective inorganic sorbent operating on a principle of an ion sieve. The apparatus contains a plurality of ion-exchange columns arranged and interconnected in sequence. Flows of the brine, flush water, acidic desorption solution, and outputs, of the processed products are controlled via switchable shut-off valves. The method can be carried out by operating the apparatus in a parallel or a serial mode of column operations. In the parallel mode, all columns work simultaneously in the same manner. In the serial mode of operation, the columns work individually with a shift of the sorption-flushing-desorption-flushing cycles sequentially and with a transfer of the processed brined sequentially from the first column to the last column and from the last column to the first one thus providing continuity of the lithium-extraction process.

The diaphragm assembly comprises a main part (13) which has a passage (14) delimited by a passage edge. The aim of the invention is to design the diaphragm opening to be temporally and geometrically variable in situ. This is achieved in that the diaphragm assembly has at least one diaphragm plate (17, 17?, 17?) which is assembled on the main part (13) so as to be movable in front of the passage (14) and back. The diaphragm assembly additionally comprises a movement device which is operatively connected to the diaphragm plate (17, 17?, 17?) in order to carry out the movement thereof.
