Zanjan Miad Samen Co. established in 1990 in the field of zinc ingot and zinc sulfate production, located in expertise zinc zone. At first phase, the company started powder zinc sulfate through spray on air alloy Zn=34% and nominal capacity 4000 tons annually which is the first private sector company in Zanjan province.
At second phase, the company attempted to set up powder Manganese sulfate via spray on air Mn=30% alloy and nominal capacity 1000 tons annually which is unique through the country (only Chinese example exists) and producing the product has been continued to supply domestic consumption of plant. And at thirds phase, zinc ingot production with Zn=99.96 ~ 99.98 and annually nominal capacity 4000 tons was exploited in February 2016.
In this section concentrates with different zinc alloys, different proportions which determined earlier and weighted by balance, provided to operator.
This unit is the greatest sector of the company which includes pulping tank, leach acid tank, neutralization tank, leach solution press filter, purification
This unit which is called electrolyze, provides quasi-complete product sheet. This unit includes trans and rectifier in order to provide proper power, cooling
Zinc sheets that obtained from sheet separating unit, melt in higher temperature then poured in Miad Samen molds and finally separated as ingot bundles
Zinc alloys have been used since many centuries ago. Brass goods referred 1000-1400 years ago, were found in Palestine and zincc things with 87% found
in Transylvania. Because of low boiling point and chemical reaction of the metal (separated zinc turned into smoke and inaccessible), real characteristics of the metal were not clear in ancient era.
Atomic weight 65.38, density 7.133, melting point 419.83 C, mohs unit 2.5, capacity 2 located in IIB periodic table, natural isotopes 68,66,64,70 and
radioactive isotopes 72ٰ,71,69,65,63,60 zinc is a soft metal hammer dining with gray luster bluish in acids, bases, indissoluble.
Zinc is ctucial element of human life which is necessary for his life and survive. Zinc loss between animals losses weight significantly. Based on many
authors, zinc contained drugs immunes cold and flue. However, there are disagreement in this issue.
Zinc is used for metals` electrical plating, to prevent corrode, zinc are used in alloys such as Nickel Silver, different formulas , silver brazing …/
Brass has more applications due to corrode and corrosion resistant. Zinc is used in die casting of automobile industry widely. And its used on pipes as a part of battery contents.
