Abstract

The present invention relates to a method for selectively extracting a salt to be extracted from a brine to be treated containing the salt to be extracted, characterized in that: the brine to be treated (S1) is sent to what is referred to as a first extraction mixing agitator (1a) to which a liquid hydrophobic organic phase is also added; the brine and the liquid hydrophobic organic phase are mixed in the extraction mixing agitator (1a); and the mixture is sent to what is referred to as a first separating decanter (1d, 1dc), to obtain: a brine from which salt to be extracted has been removed; and an organic phase loaded with salt to be extracted; the brine from which the salt to be extracted has been removed is recovered; the organic phase loaded with salt to be extracted is sent to an initial washing mixing agitator/separating decanter centrifuge (5a, 5dc or 7a, 7dc), to obtain a purified organic phase loaded with salt to be extracted which is sent to what is referred to as an "organic" heat exchanger (1e) in which it is heated before being sent to what is referred to as an initial regeneration column (1c; 2c) in which countercurrent exchange with hot water is carried out, this hot water being at a temperature higher than that of the starting brine, to obtain: water containing the salt to be extracted; and a regenerated organic phase, which has lost the salt to be extracted; the regenerated organic phase is recirculated to the initial extraction mixing agitator (1a).
