Galena is a mineral composed primarily of lead (II) sulfide (PbS). It has been used for thousands of years as a source of lead, silver, and sometimes as a semiprecious stone. Here are some of the chemical, physical, and optical properties of galena:The concentration of Fe in sphalerite decreases, whereas the concentration of Zn increases gradually from Z-Sp to X-Sp2b (Fig. 6 a, b). The concentration of Fe in sphalerite is closely related to the color of the studied sphalerite crystals. The brown sphalerite (X-Sp2b) found in XOB has the lowest Fe concentration (av. (average) = 4.19 wt%).the sample consisted of 69% sphalerite, 17% galena, and 14% silicate. The XRD spectrum of the sphalerite sample is shown in Figure 1. Method The sample was crushed by a series of jaw, cone, and roll crushers, then ground in a 5200 cm3 volume ceramic cylindrical ball mill with alumina balls to prevent possible contamination from grinding media.Sphalerite. Purchased with funds from the Tiffany & Co. Foundation in 2011. Sphalerite is zinc sulfide, an ore of zinc.

Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. Although this mineral is usually black because of various impurities, the pure material is white, and it is widely used as a pigment.

Sphalerite, which is a form of zinc sulfide, is the most heavily mined zinc-containing ore because its concentrate contains 60–62% zinc. Other source minerals for zinc include smithsonite (zinc carbonate), hemimorphite (zinc silicate), wurtzite (another zinc sulfide), and sometimes hydrozincite (basic zinc carbonate).
