Environment | ZINC. International Zinc Association
Zinc is Natural. Zinc is the 24th most abundant element in the Earth's crust and has been present since the formation of earth. All life on earth is developed in the presence of zinc. Through natural erosion processes, a small part of the zinc in soil, rock and sediment is constantly moved and transported through the environment.

Traditionally, zinc dust 1 has been employed as a reducing agent in organic synthesis. Notably, zinc dust or an amal-gam thereof has been used to reduce carbonyls2 (Clem-mensen reduction), carbon–oxygen bonds,3 carbon– halide bonds,4 alkynes,5 heteroatom bonds (N–N and N– O bonds),6 and to prepare numerous organozinc reagents.
A global life cycle assessment for primary zinc production
A common limitation across all zinc-mining and zinc-smelting companies who reported data for this study was a lack of data surrounding water treatment and discharge. For many mines, water leaks into the site and must be collected. Some of this water is used for cooling machinery, but generally, much of it is sent to treatment or …
Development of the Technology for the Extraction of Zinc …
The input of dust and sludge into the sinter charge of metallurgical plants is limited, since the secondary use of zinc-containing materials leads to the accumulation of zinc in the furnace lining and its destruction [15, 16]. The iron content in dust and sludge depends on the content of zinc and reaches 30–50%.
Zinc
Zinc is a metal that is normally found in small amounts in nature. It is used in many commercial industries and can be released into the environment during mining and smelting (metal processing) activities. People living near smelters or industries using zinc could be exposed to higher levels of zinc by drinking water, breathing air and touching …
