- Zinc is a metallic
chemical element with the symbol Zn and atomic number 30. In
nonscientific context it is sometimes called spelter.
- Commercially pure
zinc is known as Special High Grade, often abbreviated SHG, and is
99.995% pure.
- Zinc is a moderately
reactive bluish grey metal that tarnishes in moist air and burns in air
with a bright bluish-green flame, giving off fumes of zinc oxide. It
reacts with acids, alkalis and other non-metals.
- Zinc is present in a
wide variety of foods, particularly in association with protein
foods.
- Zinc coatings are
widely used to protect finished products ranging from structural
steelwork for buildings and bridges, to nuts, bolts, strip, sheet, wire
and tube.
- High purity grades
of zinc oxide are used in specialised applications such as ferrites and
in varistors to protect sensitive equipment from electrical power
surges.
- Zinc concentration
is usually done at the mine site, prior to reaching the zinc processing
plant. The concentration includes crushing and flotation
techniques.
- Electrowinning uses
an electrolytic cell to reduce the zinc. An electric current is run from
a lead-silver anode through a zinc solution. The zinc deposits on an
aluminum cathode and is harvested. The zinc is then melted and cast into
ingots.
- Zinc smelting is the
process of recovering and refining zinc metal out of zinc-containing
feed material such as zinc-containing concentrates or zinc oxides.
- Globally, two main
zinc-smelting processes are in use:
(i) a pyrometallurgical process
run at high temperatures to produce liquid zinc.
(ii) a
hydrometallurgical or electrolytic process using aqueous solution in
combination with electrolysis to produce a solid zinc
deposit.
- Zinc metal is
extracted from the purified solution by means of
electrolysis.
- Despite its
declining share of world consumption, the U.S. economy still plays an
important role in the world zinc markets, mainly because many countries
depend on exports of zinc and zinc-containing products to the United
States.
- At 270,000 t/yr,
CEZinc is one of the largest zinc processing facilities in the world;
Noranda estimated that it supplied about 15% of zinc demand in the
United States and about 35% of demand in Canada.
- The USA’s dominance
of the global zinc market has increased with mines in Alaska accounting
for more than 50% of the USA’s zinc and lead.
Zinc prices increased
sharply from a low of US$0.33/lb in 2002 to a high of US$2.09 on Nov.
24, 2006.
- Zinc demand in China
was forecast to exceed mine production by 540,000 tonnes annually;
however, destocking led to an actual deficit of 320,000
tonnes.
- Zinc metal exports
from China declined to 465,900 tonnes in 2003 and 223,900 tonnes in
2004. With these declines, China became a significant net importer of
zinc
