ABSTRACT: Method for the recovery of zinc, copper and lead of oxidized and/or sulfurized ores and materials from various feedstocks by lixiviation with a concentrated solution of sal ammoniac, resulting in the formation of the corresponding amines, and separation of those metals fromt he fertile solution obtained by means of organic acid extractants (cationic extractants and/or cholators) which are neutralized by the amine regenerating the original solution of sal ammoniac. The copper and zinc which separately have passed the corresponding organic phase are reextracted therefrom taking advantage of the sulphuric acid obtained in the electrolysis of the corresponding solution. The lead is separated by crystallization and obtained in the form of chloride.
