Abstract

A process for obtaining dissolved salts and acids from other available ones, by means of ion exchanging resins, is done in two stages, placing the changing resin in columns 10, 20. In the first stage the resin 10 is charged with the cation corresponding to the salt which it is desired to obtain by passing a solution of a suitable salt through the resin. The resin thus charged is cyclically extracted from the column 10 at the same time that it is replaced by regenerated resin from the second stage of the process. Before making the resin used in the first stage 10 pass to the second 20, it is released from the salt solution with which it was charged (at 14), by means of draining and washing with water, or by shifting with another solution. In the second stage of the process, the resin 20 is regenerated by having it pass through a solution of a salt or an acid, the anion of which is the one corresponding to the salt which it is desired to obtain. <IMAGE>
