The Chahmir zinc-lead deposit (1.5 Mt @ 6 % Zn + 2 % Pb) in Central Iran is one among several sedimentary-exhalative Zn-Pb deposits in the Early Cambrian Zarigan-Chahmir basin (e.g., Koushk, Darreh-Dehu, and Zarigan). The deposit is hosted by carbonaceous, fine-grained black siltstones, and shales interlayered with volcaniclastic sandstone beds.

The reason of this research is to identify the favorable areas for copper, zinc, and lead mineralization in the western part of the 1:100,000 Tafresh geological Sheet in the Urmia-Dokhtar structural zone of Iran. Effective data layers for mineralization, such as geology, geochemistry, structures, and satellite images, were analyzed and then integrated using the AHP-OWA …

ZINC & LEAD. Iran has over 220 million tons of proven zinc and lead ore reserves, and the country has 5% of the world's constituent reserves. In 2009, 165,000 tons of zinc and lead were produced, 77,000 tons of which were exported. Iran Zinc Mines Development Group is the largest producer, accounting for up to 80% of production.

The scope of this study was to recover oxide lead and zinc minerals from Aladağ Region (KayseriTurkey) ores. Primary studies carried out with this ore have shown that flotation of oxidized lead and zinc minerals, in particular zinc minerals was difficult (Engin and Önal, 2003).
