Ores The three most common ore minerals are galena sphalerite and pyrite What are ores give example Ores are minerals that have a high concentration of a certain element typically a metal Examples are cinnabar (HgS) an ore of mercury sphalerite (ZnS) an ore of zinc or cassiterite (SnO2) an ore of tin (Mineral).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.
