Zinc processing - Ores Britannica

Ores. Zinc ores are widely distributed throughout the world, although more than 40 percent of the world’s output originates in North America and Australia. The common zinc-containing minerals are the zinc sulfide known as zinc blende or sphalerite (ZnS), a ferrous form of zinc blende known as marmatite [(ZnFe)S], and a zinc

Division of Geology and Mineral Resources - Zinc

Zinc is a bluish-white, lustrous metal with the chemical symbol Zn. Its main ore mineral is sphalerite (ZnS). Some of its uses are for galvanizing (plating thin layers of zinc onto iron or steel to protect from corrosion), production of brass (combination of zinc and copper), and coloring in rubber and paint.

The main zinc mineral is sphalerite ((Zn,Fe)S), which contains up to 67% zinc by mass. Smithsonite (ZnCO3, 52%), willemite (Zn2SiO4, 59%) and hemimorphite (Zn4Si2O7(OH)2 H2O, 54%) may occur in the near-surface weathered or oxidised zone of an orebody. In some cases, these secondary minerals are also zinc ores.

How do we extract minerals? - USGS

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 metal.
