Zanjan Miad Samen Co. 


 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.

History and zinc industrial applications 

  • History

    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.
