3. Zinc - Wikipedia

   en.wikipedia.org/wiki/Zinc

   About 70% of the world's zinc originates from mining, while the remaining 30% comes from recycling secondary zinc. [109] Commercially pure zinc is known as Special High Grade, often abbreviated SHG, and is 99.995% pure. [110] Worldwide, 95% of new zinc is mined from sulfidic ore deposits, in which sphalerite (ZnS) is nearly always mixed with ...

   Zinc is a strong reducing agent with a standard redox potential of −0.76 V. Pure zinc tarnishes rapidly in air, rapidly forming a passive layer. The composition of this layer can be complex, but one constituent is probably basic zinc carbonate, Zn 5 (OH) 6 CO 3. [8] The reaction of zinc with water is slowed by this passive layer.
