Abstract

The famous Um-Gheig area bearing Zn-Pb deposit have a great economic importance in Egypt, this is due the high economic potentiality. The current work is design to recover of Zn and Pb which assays 17.16% of ZnO and 1.6% Pb. Galena, sphalerite, and pyrite are the primary minerals, while oxides and carbonates of lead, zinc, manganese, and iron are the secondary. Zn and Pb dissolving are controlled by chemical reactions. The activation energy (Ea) were obtained to be 28.956 and 24.618 kJ/mole respectively. Shifting the focus to extract 99.7% zinc (Zn) using acetic acid, followed by lead (Pb) precipitation .
