Zinc - Simple English Wikipedia, the free encyclopediaZinc is not found as a metal in the earth's crust. Zinc is only found as zinc compounds. Sphalerite, a mineral that is made of zinc sulfide, is a main ore of zinc. Very little zinc is in the ocean. Zinc ore is normally found with copper and lead ores. There are some other zinc ores, such as smithsonite (zinc carbonate) and a zinc silicate ...
