Sphalerite, zinc sulfide, is and has been the principal ore mineral in the world. Zinc uses range from metal products to rubber and medicines. Zinc alloys readily with other metals and is chemically active. On exposure to air, it develops a thin gray oxide film (patina), which inhibits deeper oxidation (corrosion) of the ... The most significant chalcopyrite deposits to be mined are hydrothermal in origin. In these, some chalcopyrite occurs in veins and some replaces country rock.

Mineral characteristics Textures: Mineral grains are typically medium to coarse grained (0.5 to >1 cm), and range in texture from euhedral to massive interlocking grains. Trace element contents: In many deposits, sphalerite typically has very high iron contents (5-20 mol percent) and Sphalerite from the sediment-hosted Dolostone Ore Formation (DOF) Cu-Co-Zn deposit, in northwestern Namibia, has previously been shown to contain extremely high concentrations of the critical metal Co (up to 1 wt%). These concentrations are the highest reported in sphalerite to date, and the how and why of sphalerite being able to incorporate such high concentrations of Co are poorly ...These are followed by consideration of the paragenesis, formation conditions, and fluid inclusion geothermometry, and by two chapters on the ore mineral assemblages of igneous rocks and vein ...Uses of Arsenopyrite and Arsenic. Arsenopyrite is the primary ore of arsenic metal. The mineral contains approximately 46% arsenic by weight. Arsenic metal is used to produce a variety of alloys. It was historically used to harden lead in ammunition, but this use was nearly eliminated by the late 1900s.
