    Mar 21, 2017 Analyses of sphalerite minerals from the characteristic brecciated Zn–Pb ores of the main ore body in the giant Dongshengmiao deposit have revealed variations in δ 66 Zn from 0.17 to 0.40‰ and in δ 56 Fe from −1.78 to −0.35‰. Further, the investigated pyrrhotite samples have iron that is isotopically similar to that of associated sphalerite minerals.

    Apr 17, 2020 Abstract: The present work reports the direct leaching of zinc from a sphalerite concentrate in acid media. Lab-scale and pilot-scale experiments were conducted in atmospheric-pressure and low-pressure reactors, respectively. Leaching of zinc and precipitation of iron was achieved in the same stage using di erent reagents like Fe3+, O 2, O3, and Fe

    Sphalerite: Meanings, Properties and Powers

    Sphalerite Properties. Sphalerite is a zinc ore, and its name pertains to the Greek word that means ‘treacherous’. This is because it looks a lot like Galena, only it does not contain lead, much to the disappointment of early miners.. Sphalerite is a significant zinc ore which is usually found in hydrothermal veins.
