Résumé
The not transformed solid rejection by accumulated storage atfree air of ZnO leaching operation in zinc refineries constitutes a threat for the natural environment. Muds contain more than twenty four chemical elements to variable proportions, The most significant are iron and zinc.In this work we consider residues treatment as the technical solution for residues accumulation problems. Delocalization or buried storage even under insulated membrane cannot constitute environmental protection, Zinc was recoveredfrom the solid residue more than rate of J 3 % by setting in acid solution and iron elimination by jarosite precipitation under insoluble complexform.
