Zinc is primarily extracted from ore containing zinc sulfide, zinc blende, or sphalerite. The countries mining and producing the most refined zinc, in descending order, are China, Peru, Australia, the United States, and Canada.
How do you identify zinc?
Without an analyzer, a simple way to sort zinc and lead is to check their hardness. Use a knife to cut — or side cutters to squeeze — the material. If it is soft it is lead; if it is hard it is zinc.
What are 3 uses of zinc?
Zinc is also used in alloys such as brass, nickel silver and aluminium solder. Zinc oxide is widely used in the manufacture of very many products such as paints, rubber, cosmetics, pharmaceuticals, plastics, inks, soaps, batteries, textiles and electrical equipment.

How many isotopes does zinc have?
With the middling atomic number 30, it has five stable isotopes of atomic weight from the dominant zinc 64 to zinc 70, plus an extra 25 radioisotopes. Because of its hazy origins, it's difficult to pin down one person as the discoverer of the element.
What is zinc used for?
Uses. Most zinc is used to galvanise other metals, such as iron, to prevent rusting. Galvanised steel is used for car bodies, street lamp posts, safety barriers and suspension bridges. Large quantities of zinc are used to produce die-castings, which are important in the automobile, electrical and hardware industries.
How much zinc is in the human body?
Zinc is essential for all living things, forming the active site in over 20 metallo-enzymes. The average human body contains about 2.5 grams and takes in about 15 milligrams per day. Some foods have above average levels of zinc, including herring, beef, lamb, sunflower seeds and cheese.
What is density in science?
Density is the mass of a substance that would fill 1 cm 3 at room temperature. Relative atomic mass. The mass of an atom relative to that of carbon-12. This is approximately the sum of the number of protons and neutrons in the nucleus.
Where was zinc first used?
Zinc was known to the Romans but rarely used. It was first recognised as a metal in its own right in India and the waste from a zinc smelter at Zawar, in Rajasthan, testifies to the large scale on which it was refined during the period 1100 to the 1500.
How are elements organized into blocks?
Elements are organised into blocks by the orbital type in which the outer electrons are found. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). The number of protons in an atom.

Occurrence
Physical Characteristics
Chemical Characteristics
- Zinc is a reactive metal. The surface of zinc metal is quickly tarnished as it reacts with the carbon dioxide present in the air and forms a layer of zinc carbonate. It is a strong reducing agent . Zinc readily reacts with non-metals, acids and alkalis. In the presence of concentrated sulfuric acid, the upper passivating layer of zinc carbonate is dissolved and lead to the release of hydrogen gas. T…
