A process for the production of calcium bromide from feed brines,
particularly from Dead Sea End Brine (EB), is described. The process
comprises extracting the feed brine in countercurrent with a composite
organic solvent; optionally, purifying the extract to increase the ratio
Br:Cl by contacting it with a part of the product; and washing the
purified extract with water to yield the product, that is an aqueous
solution of CaBr.sub.2. The composite solvent comprises an anionic
extractant, such as an amine or a mixture of amines; a cationic
extractant, such as a carboxylic phosphoric or sulphonic acid or a
mixtures of said acids; and diluent/modifier, which is an organic
solvent. An apparatus for the production of calcium bromide is also
described, which comprises: an extraction battery; optionally, a
purification battery; and a washing battery, wherein at least one of the
batteries comprises a plurality of stages.
