2021-4-21  The US has few uranium resources. Global reserves of uranium are expected to decrease starting in 2040 and become depleted by 2100. Zinc has a moderate abundance in many soils and is commonly found in ore deposits called sphalerite. Zinc was discovered around 3000 BCE in the Middle East and was later used as a component of brass.

2021-11-20  Sphalerite, zinc sulfide, is and has been the principal ore mineral in the world. Zinc uses range from metal products to rubber and medicines. Zinc alloys readily with other metals and is chemically active. On exposure to air, it develops a thin gray oxide film (patina), which inhibits deeper oxidation (corrosion) of the metal.

2008-10-30  e-mail address: [email protected] Abstract Mine exploitation of zinc-lead ore deposits within the Triassic Bytom Trough lasted from the 12th century until 1989. Its zinc and lead ore depos-its are related to the so-called ore-bearing dolomites series of the Middle Triassic. In the mid-seventies of the 20th century, five zinc and lead ore
