The oldest mineralogical records in Iran are related to the Firouze Neyshabour mine and the Celtic Zara copper mine dating back to 4-5,000 years BC.
All activities of lead and zinc mines were almost antiquated before World War II. In the 1930s, German experts brought to Iran new mining methods, especially in the field of metal mines. At this time, the lead and zinc mines of the Nakhlak, the Black Sea, Anarak, Bibi Shahranoi and several other mines were active. Lead and Zinc mines were well-developed in the years 1946 to 1975. The first modern zinc-zinc concentrating plant was exploited in 1340 with the help of a French company in Lakan, Central Province. From 1962 to 1993, the mines on Iran were exported out of the country after processing as concentrates. After the imposed war, due to the existence of the Anguran mine, the views of domestic experts focused on the acquisition of Zinc metal technology. In this regard, extensive national research was conducted to obtain zinc ingot technology from Anguran concentrate and ore and lead to the production of the first zinc ingot On a pilot scale in 1371.
Since 1993, zinc ingot production has started at Iran Mining Processing Company (Zanjan Melting Unit), and since then, with the construction and commissioning of a new unit called Roein-e-Shams in Zanjan, zinc ingot production in the country has risen along the way. Made This unit has mainly been engaged in the production of zinc ingot by using internal acquisition technology. Currently, the Khosse Zazan Company on Zanjan, as the largest bullion manufacturing plant in the Middle East, is owned by the previous shareholders of Roein Sharms, a leading zinc industry in the country.
