Zinc is one of the basic metals that has many benefits in addition to
other non-ferrous metals such as copper, lead, aluminum, and nickel. In
general in Indonesian it is better known as zinc. Zinc itself is the
fourth most common type of metal produced after steel, aluminum and
copper. The melting point can reach 450 degrees Celsius. As one of the
base metals, zinc has many different applications and is very much
needed in modern life today. Among others, it is used to fabricate steel
components in the form of die casting alloys and as brass which is an
alloy of zinc and copper.
Meanwhile, the majority of zinc is
applied for corrosion protection or galvanizing in steel by forming a
barrier surface on steel so that it is resistant to corrosion. Zinc is
also applied in the form of oxide (zinc oxide) which has benefits in the
formulation and vulcanization of rubber and tires, zinc oxide is also
used as fertilizers and a small portion is used in the field of pharmacy
and use in the pharmaceutical field and use in the medical field. World
zinc consumption continues to grow, from around 5 million tons per year
in 1970 to more than 8 million tons per year in the late 20th century,
and to 9.7 million tons per year in 2003. World demand for zinc has
increased by 2% per year .
According to fact research, the fact is
that the galvanic process consumes around 3 million tons of zinc per
year or shows about 30 million tons of steel per year which has been
through hot dip galvanized processes and is used in all forms, or other
data that says 40% of all zinc products in the world. This proves that
corrosion protection through galvanizing is a method favored by
practitioners who are engaged in corrosion because it has steel.
In
Indonesia alone, zinc processing plants still don't exist. Besides
because there is not always a lot of raw material available in the form
of zinc core (the potential for minerals in Indonesia is large, among
others, bauxite, copper and nickel), also processing technology that
requires large investments, but Indonesia has a large potential for
resources zinc. Because of that, there are mostly zinc imports from
Korea, Australia and Japan.
