摘要

Procedure for the recovery of zinc from solutions containing it, especially those obtained in the wet treatment of different minerals and pyritic products, such as pyrite ashes, natural pyrite wash waters and those from of the drainages of the mines of said mineral, characterized in that it is added to the cyclic solution, if it does not previously contain it, chloride ion up to a concentration of at least 2m, so that the zinc forms a complex of anionic character cl4zn, in the form of which it comes in contact with a strongly basic anion exchange resin, which retains it and from which it is then eluted with water, the resin being simultaneously regenerated.
