Zinc (Zn) In the Earth's crust, zinc is the 23rd most plentiful element. Zinc blende, commonly known as sphalerite (ZnS 2), is the most common ore (ZnS). Wurtzite, smithsonite, and hemimorphite are three more major zinc ores. Canada, Russia, Australia, the United States, and Peru are the primary zinc-mining countries.
