Abstract
Elimination procedure for aluminium in electro-chemical roughening baths, particularly for the manufacture of dies, including one or more columns containing resins with ion exchange (in which a treatment liquid is made to pass), inorganic and/or organic acids, and a variable quantity of aluminium in ionic form (in general between 0.1 and 1 g/l). During the passage of the treatment liquid the aluminium is retained from the resin and the bath which emerges is restored to its functionality.
