Zinc ore refers to naturally occurring rocks and minerals that contain significant amounts of zinc (Zn), a bluish-white metal known for its corrosion resistance and versatility in various industrial applications. The most commonly mined zinc ore is sphalerite (ZnS).
Composition:
Primary Mineral: Sphalerite (zinc sulfide - ZnS)
Other Zinc-bearing Minerals:
Smithsonite (zinc carbonate â?? ZnCOâ??)
Hemimorphite (zinc silicate â?? Znâ??Siâ??Oâ??(OH)â??�·Hâ??O)
Zincite (zinc oxide â?? ZnO)
Associated Elements: Often found with lead (Pb), silver (Ag), iron (Fe), and cadmium (Cd)
Geological Occurrence: Found in sedimentary, hydrothermal, and metamorphic deposits worldwide, with large reserves in Australia, China, Peru, the U.S., and India
Uses of Zinc:
Galvanization
The primary use of zinc is in galvanizing iron and steel to prevent rust and corrosion.
Alloy Production
Used to create brass (zinc + copper) and zamak (zinc + aluminum + magnesium), commonly used in hardware, tools, and automotive parts.
Batteries
Essential in alkaline batteries and zinc-carbon batteries, and gaining interest in zinc-air and zinc-ion battery technologies.
Die Casting
Due to its excellent castability, zinc is widely used in automotive, electrical, and consumer product manufacturing.
Chemicals and Pigments
Used in the production of zinc oxide (ZnO) for rubber manufacturing, sunscreens, paints, and ceramics.
Agriculture
Zinc compounds (like zinc sulfate) are used in fertilizers and animal feed supplements to correct zinc deficiencies in crops and livestock.
Pharmaceutical and Health Products
Zinc is an essential trace element in the human body and is used in dietary supplements, lozenges, and topical creams.
