Abstract

Improvements introduced in the object of the main patent no. 304.601, granted on October 15, 1964, by: A procedure for the recovery of zinc from the ferrites, characterized in that the leaching of the residues is carried out, at least, in two stages, attacking the residues in the first stage with a weakly concentrated acid, sufficient so that at the end of this stage its concentration is not less than 5 g/liter, the residues of this first stage are then attacked in a second stage with acid whose concentration is approximately 300 grams/liter.
